Your computer will lag behind and you want to give it a boost? Add them to memory.
By increasing the RAM on your computer's hard drive, which is slower, be less stressed when you open multiple windows or tabs at the same time,
when you manipulate large files when you launch your software when you play, etc. .
In the end, then you will reap improved performance of your computer and a greater working comfort. Whether to improve the performance of a desktop,
a laptop or netbook, adding memory is accessible to everyone.
Just as a first step to check the type and characteristics of the memory used by your computer to see which modules you must buy (DDR, DDR2, DDR3 SO-DIMM, ...) and how much memory you can add. The number of memory connector on the laptop is indeed limited. The manufacturer is Crucial to this analysis tool free online that will automatically give you this information.
Then, by a simple trapdoor under your laptop and your netbook and directly into the housing of your computer, you can easily add your new module and extend
the capacity of RAM your computer.
All you need to finally verify that the module is properly recognized by your computer and Windows.
Find memory compatible with your computer:
With the Crucial manufacturer's online scan tool, you can easily find the type of memory your computer's speed, but also the quantity that you can add.
~So open Crucial site and click the Scan button on my system under Tools Crucial System Scanner.
~Check the box By checking this box and clicking ... and click Scan my system.
~In the dialog box that appears, click Run.
~Allow the program to then make changes to your computer by clicking Yes.
~Your browser is then open to a page showing the results of the analysis. The amount of memory installed, the type and number of free sites are listed. Here,
two memory locations are present which is already used by a module 2GB
~Information on the system manufacturer and model of motherboard are also shown.
~Fill out the form with the information: the manufacturer of your computer or your motherboard in the case of a PC assembler, the range and the model name.
Click Search.
~The service presents you with the recommended memory module for your computer.
~Below, the characteristics of your computer or your motherboard are shown. We learn here that the maximum amount of memory is 4GB
~In our case, we have a site made by 2GB of memory, 1 free slot and 4 GB may not be exceeded. The 2GB module is therefore proposed.
Windows, Linux and the limit of 3 GB:
Most operating systems like Windows or Linux are available in two versions: 32-bit and 64 bit. The difference between the two? The 32-bit Windows or
Linux knows how to use a maximum between 3 and 3.5 GB of memory (depending on your device: graphics card, sound card ... which require a memory area).
The 64-bit version has virtually no limit (Family Premium Windows 7 handles for example up to 16GB of memory).
Note that to use a 64 bit system, only the processor must be compatible 64-bit. Currently, almost all processors on the market are 64-bit,
32-bit processors is at least anecdotal. The Intel Core 2 Duo, Core 2 Quad, Core i7, Core i5, i3 Core, or AMD Athlon 64 X2, AMD Phenom X2/X3/X4/X6
are all built on a 64-bit architecture.
If you have a 32bit system, so there is virtually no interest in going beyond 3 GB of memory.
If you want to go beyond, turn to a 64 bit system. Note that the box of Windows 7 offers two versions: 32 and 64 bit and you can install the one you want. Also,
be aware that it is not possible to update a 32-bit Windows for 64-bit version. You will need to perform a full installation.
Adding memory to your Desktop:
Installing a new memory module in a computer is fairly simple and accessible to everyone. Here is how:
~ Unplug all cables and open the box.
~ Locate the slots for memory cards.
~ Spread the lugs memory locations.
~ Insert the memory module in an open location (right next to one used), making sure to align the notches on the card with the connector.
Keyed to two thirds of the bar and the connector allows you to put the card in the right direction.
~ Firmly press the memory module: the lugs just block the card. Make sure they are well adjusted.
~ Your memory modules are properly placed. Close the PC case and reconnect all cables.
~ Turn on your computer. From the start, the new strip and detected and the overall amount of memory your computer is updated.
~ Windows also recognizes the new amount of memory available.
~ Windows Vista and Windows 7, Windows Experience Index should also be updated.
Add memory to your laptop:
To add your new memory module in your laptop, it's very simple.
~ Turn off your first laptop, unplug it and remove the battery.

the memory modules.
~ If you replace a memory module, spread carefully and clamps at each end of the connector of the memory module until the module so.
Then remove the module from the connector.
~ Then install the new memory module. Align the notch on the edge of the module with the guide pin located in the connector slot.
Slide the module firmly into the slot at an angle of 45 degrees, then slide it down until you hear click.
~ Then store the cache memory and screws. Insert the battery in its bay, connect the adapter to your computer and restart your computer.
~ At startup, the computer detects the additional memory and automatically updates the system configuration information. Press any key (F1 in our case)
to continue booting.
~ To check the amount of memory installed, click the right mouse button on the My Computer icon on the desktop and choose the Properties command.
~ In the window that appears, the amount of memory recognized by Windows is displayed.
Add memory to its netbook:
Installing the new memory module is very simple and will take about ten minutes. At first, you must remove the memory module already installed,
which occupies this unique position in the netbook.
~ Shut down your Netbook.
~ Unplug it and disconnect all USB devices connected to it.
~ Close it and return it.
~ Locate the small door giving access to memory. This usually involves a small token of memory or memory includes an indication.
~ Remove the screws using a small screwdriver.
~ Remove the lid of the trap. The memory module appears.
~ Remove the clips at both ends of the memory module.
~ It rises.
~ Carefully remove the memory module.
~ Now that the site is free, you can install your new memory module. Take your new memory module.
~ I ntroduce him to his location, taking care to coding.
~ Push the memory module, while leaving the ramp.

~ Enter 10002 in the Value data field. Click OK.
~ Finally close the registry editor, then restart your computer for the change to take effect.
Saving the memory in case of crash:
When your system fails, you can create an image of the memory of your system that you can use to find the cause of the error.
You can choose between several types of memory dumps. Complete memory: The full memory dump records the entire contents of memory before the system shuts down without explanation. Its size is equivalent to the amount of RAM installed on your computer, which you must add 1 Mo. It is therefore worth a lot of disk space to store this image. So if you have 512 MB of RAM, will dump a 512 + MB or 513 MB Kernel memory: The kernel memory dump records only the memory allocated to the kernel of Windows XP, hardware, operating systems and programs executed by the system. It therefore excludes the memory allocated to software executed by users. The backup process on the hard disk and is accelerated in the event of a crash. The size of the kernel memory dump is approximately one third of the total amount of RAM installed on your computer. This type of image is most interesting, since it is much smaller than the complete memory dump, and it neglects only the memory areas that do not appear to have any relation with the problem. Memory Dump: Finally, the memory dump records the minimum information necessary to identify the cause of the crash. The memory dump saves in less than 64 KB: the stop message and parameters, the list of drivers loaded, the process context, information on the process stopped, the information on thread that stopped.
The memory dump can be useful if you have limited disk space. But you have less chance of finding the cause of errors in the examination, because of the lack of information retrieved.
To set the type to create memory dump during a crash, you must change the system settings.
~ Click the right mouse button on My Computer, then choose Properties.
~ In the System Properties dialog box that opens, click the Advanced tab.
~ Then click the Settings button under Startup and Recovery.
~ Pull down list then Writing debug information, then select the type of image you want to create in a crash, Kernel memory, for example, and click OK.

Insert your Windows XP CD in your drive.
~Then click the Start button, then Run.
~Then enter in the Open text box the following command: E: \ i386 \ winnt32.exe / cmdcons where E: is the drive letter in which your Windows XP CD.
~Confirm the installation of the Recovery Console by clicking the Yes button in the dialog box that appears.
~If you are connected to the Internet, the installer tries to download the Recovery Console from the Microsoft website. Press ESC to install directly from your Windows XP CD.
~After a few seconds, a message appears to indicate that the Recovery Console is installed. Click OK, then restart your computer.
~When you next start the computer, Recovery Console will be added to Windows startup menu.
Improving the functionality of the Recovery Console:
By default, access to all drives and all folders on your hard drive and the diskette are not allowed in the Recovery Console. Only the folder where Windows is available.
To change this and allow you to access all folders on your hard drive and all your readers, which is convenient to perform a backup last minute of your sensitive documents, you need to change local security setting.
~Open the Control Panel by clicking Start, Settings, then Control Panel.

Linux provides a DD command which is the powerful UNIX utility. It makes use of Linux kernel makefiles to make boot images.
DD can be used to copy data from one device to another or from one location to another.
Administrator is the only person having rights to execute DD command. You can use the below DD command in Linux operating
system which will help you in various ways.
The uses of DD command are as follows:
~ If you want to take the backup data from one hard disk to another hard disk within the same system. The command is given below:
Code:
# dd if=/dev/sda of=/dev/sdb
~ In this “if” specifies input file name and “of” specifies the file where the data has to be copied. If you mention source device in target device and vice versa then you might loss all your data.
~ If you want to restore the hard disk with the image file of another hard disk then use the following command:
Code:
# dd if=hdadisk.img of=/dev/hdb
~ To copy the data from the floppy into the image format you need to type the following command:
Code:
# dd if=/dev/fd0 of=myfloppy.img
In the input file specify the name of floppy location and in output give the name of floppy image file.
~Type the below command to read data from one location and write it to another location. The command is given below:
Code:
dd if= of= bs= ("USUALLY" some power of 2, and usually not less than 512 bytes (ie, 512, 1024, 2048, 4096, 8192, 16384, but can be any reasonable whole integer value.) skip= seek= conv=< conversion >
~ If you want to remove CD, DVD or USB from the system then type the below command. This command will rescue it from the system.
Code:
~ You can backup a partition. For taking the backup you need to specify the partition name in input file and then specify the path or image file where you want to take backup. The dd command for taking backup is given below:
Code:
# dd if=/dev/hda1 of=~/partition1.img
~You can create an iso file from the source file. So we can enter the CD or DVD and create an iso file from the data contained in them. The dd command for creating iso is given below:
Code:
# dd if=/dev/cdrom of=tgsservice.iso bs=2048
Thus dd command reads one block at time, executes it and writes to the targeted output file.

Sebelumnya, bagi yang belum tahu apa itu Torrent, koneksi Peer To Peer, mari kita baca terlebih dahulu pengertian dasar dibawah ini.
* P2P : Komunikasi dua arah antara PC yang satu dengan PC yang lain yang terhubung secara langsung. Biasanya digunakan untuk sarana transfer file dimana antar keduanya terdapat aktifivas download dan upload, dan saling berbagi file.
* Torrent: adalah protokol peer2peer. untuk membagi sebuah file, tapi tidak hanya menggunakan satu pihak sebagai server (yang melayani). pihak-pihak lain (client) akan ikut berbagi file yang telah mereka download. Intinya ini adalh protokol berbagi, anda yang sudah kelar mendownload harus berbagi dengan pihak-pihak yang masih mendownload.
* Seed: adalah pihak yang memiliki bagian file yang lengkap. semakin banyak seeder, semakin tinggi kecepatan download anda.
* Peer: adalah pihak yang tidak memiliki bagian file yang penuh. para peer ini akan terus saling berbagi bagian file yang mereka miliki.
* Ratio: adalah perbandingan antara berapa banyak anda mendownload dan berbagi dengan pihak lain (upload). Ratio yang normal biasanya adalah 1, artinya untuk tiap byte yang anda download, anda juga sudah mengupload satu byte (berbagi dengan pihak lain sebanyak satu byte).
* Leecher: ada dua pengertian. Pertama peer yang belum memiliki bagian file sedikitpun, sehingga tidak dapat ikut berbagi. Kedua adalah pihak dengan ratio yang sangat buruk.
Nah kesimpulannya adalah torrent merupakan salah satu cara untuk berbagi file dengan memanfaatkan protokol peer to peer yaitu satu kesatuan komputer majemuk yang saling berbagi. Semakin banyak seed(pembagi file) semakin cepat hasil download yang akan anda terima dan semakin sedikit pembagian file ke Peer (penerima file atau komputer yang belum memiliki file secara utuh) semakin kecil bandwidth yang akan anda habiskan.
secara default, setting Download dan Upload adalah “0″ atau Unlimited
masuk ke Options – Preferences – Bandwidth

You plug as usual your external hard drive to your computer to retrieve its contents or to add files when Windows offers to format it. Your hard drive has serious problems you'll have to try to solve in order to, most importantly, recover your files, and repair your hard drive to it again as usual.
* Immediately click the Cancel button.
* Right-click the Computer icon on the Start menu or desktop and click Manage.
* In the window of Computer Management, scroll down to Storage and click Disk Management.
* The list of drives connected to your computer appears. Among them, your hard disk is now reluctant. This means that it works and is recognized by the system.
* However, its file system is shown as RAW, is to say raw data unreadable by Windows.
Download and run TestDisk:
TestDisk is a free software that will allow you to help recover lost partitions and repair the partition table corrupt your hard drive. You can download TestDisk from here.
* Once the download is complete, click the Open button.

* Open the folder testdisk-****.
* Then open the folder win.
* Double click on the file so testdisk_win.exe.
Analyse your hard drive:
TestDisk can check the structure of the partition table of your hard drive to locate all partitions, even those who have disappeared.
* With the arrow keys, select Create and press the Enter key.
* Your hard drives are then detected and listed. With arrows, select the disk that you are unable to access and press Enter.
* Testdisk automatically detects the type of the partition table of your hard drive. Press Enter.
* Select the scan option and press the Enter key to verify the structure of the partition table.
* Press Enter.
* If the partitions have been created on Windows Vista, Windows 7 or if in doubt, press the Y button.
* The partitions found on the disk are displayed.
* Select Write to write the new partition table.
* Select the partition which has disappeared from Windows and press the p key. The list of folders and files on the disc is displayed.
Recover files:
With TestDisk, you can easily access the contents of a RAW partition even if it is not available under Windows. It is thus possible to recover all your files and put them in a safe place on another hard drive.
* To save a folder and all its contents to another hard disk, select it and press the c button.
* Select a folder on another drive and press the Y button. Note that the file .. you will get into the folder tree.
* Press the Y button.
* The selected folder and all its content is copied and placed in secure location on another disk drive. Copy the message thus indicates that the copy is complete.
* Repeat for other folders and files to backup and then press the Esc key or Q.
* If all the partitions appear to be much missing from the list, select Write to rewrite the partition table.
* Press the Y button to confirm.
Recreate the boot sector:
The problem may be your server's boot partition is corrupted. TestDisk will allow you to repair it.
* Select Advanced and press Enter.
* Select the partition RAW, move the slider to boot and press Enter.
* Select Rebuild BS and press the Enter key.
* Confirm the restoration of the backup boot sector by pressing the Y button.
* At the end of the transaction, your boot sector is repaired. Select Quit and press Enter.
* Then restart your computer to verify that your score is no longer blocked in RAW.
Recreate the partition:
If, despite the previous manipulations, your hard disk is locked in RAW, the last solution is to delete the partition and recreate recalcitrant. Well, so be sure to get all the files you need by following the instructions of his step Recover files. Once you've backed up your files in a safe place, you can use the freeware GParted partitioning to recreate the partition.
At first, create a bootable CD GParted, following the explanations of our file, partitioning a hard drive with Windows XP (it works of course with all versions of Windows). You will need to download GParted Live , Burn the ISO of GParted Live on a CD and Booting the Live CD of GParted .
* In GParted, click the right mouse button on the recalcitrant partition and click Delete.
* The partition is removed. Then click the right mouse button on the unallocated space that appears at the site and click New.
* Scroll File System and select NTFS.
* Reduce if necessary the size of the partition (for leaving the unallocated space to create a second) and click the Add button.
* Then click the Apply button.
* All data on the partition will be deleted. You must be sure that I saved your important files with testdisk. Confirm the operation by clicking Apply.
* Finally, click on Close. The partition of your hard drive is no longer in RAW, is a virgin and is usable again.
* Then press Enter and restart your computer.

Did you know you can drag & drop files and folders to the command prompt windows (and to any open window in the task bar)?
For example, a trick that I use is this:
Suppose you want to run a DOS command on a particular folder (ex: "C:\Winnt\system32\drivers\etc")
1 - Open the command prompt (Start->Run->cmd.exe) or use the shortcut
2 - Open a Windows Explorer window and go to the parent folder (ex: "C:\System32\Drivers")
3 - On the DOS windows type CD " (leave the quote!)
4 - From the Explorer window, drag the folder (you'll see a small square with a PLUS sign) to the taskbar over the Command Prompt window until it pops up again, then release the mouse over the command prompt.
5 - The full path to the folder is written in the command prompt. Just add the closing quote and away you go! It is faster that writing the whole path if the directory is various levels deep!
When you use CMD.EXE, there are various extensions which are enabled by default. To enable/disable perform the following
1.Start the registry editor (regedit.exe)
2.Move to HKEY_CURRENT_USER\Software\Microsoft\Command Processor
3.Double click on EnableExtensions
4.Set to 1 for them to be enabled, or set to 0 for extensions to be disabled
5.Click OK
You can also enable/disable them for a specific command session by using the appropriate qualifier to cmd.exe
cmd /y disables command extensions for this cmd session
cmd /x enables command extensions for this cmd session
In this post I will provide 5 tips for using memory efficiently in kernel-mode drivers for the Microsoft Windows family of operating systems.
Using memory wisely can help improve driver performance. Here are 5 tips for efficient memory use.
1.Lay out data structures efficiently and reuse them when possible
When designing your driver, plan your memory allocations according to type of memory, size, and lifetime. Combine allocations of similar lifetimes, so that you can free unused memory as soon as it is no longer needed. Don’t mix structures of greatly different sizes in the same allocation unless you can be sure that they will be aligned appropriately.
Reuse structures instead of freeing them and later reallocating memory for other uses. Reusing structures avoids additional reallocations and can help prevent fragmentation of the memory pool.
Drivers often require additional memory while handling I/O requests. A driver might allocate a memory descriptor list (MDL) or internal buffer to use for a specific I/O request or might need to allocate an IRP to send to lower drivers. The size of these structures varies depending on the request. The size of an MDL, for example, depends on the size of the buffer it describes.
If your driver has a technique to limit I/O size or to split up a large I/O request, you could make the buffer a fixed size, thus fixing the size of the MDL and making the buffer reusable.
Keep in mind that all performance issues involve tuning and balance. As a general rule, you should optimize for the most frequent operations, and not for unusually large or small requests that rarely occur.
2.Allocate nonpaged pool memory for long-term use at start-up
Drivers normally use nonpaged pool memory for long-term I/O buffers. Because nonpaged pool becomes fragmented as the system runs, drivers should preallocate memory that they will require for long-term structures and deallocate it when the device is removed. For example, a driver that always performs DMA, creates several events, and uses a lookaside list should allocate memory for those objects at startup in a DriverEntry or AddDevice routine and free the memory as part of handling the device removal request.
The driver should not, however, preallocate excessively large blocks of memory (several megabytes, for example) and try to manage its own allocations within that block.
Appropriate memory allocation routines include ExAllocatePoolWithTag, ExAllocatePoolWithQuotaTag, ExAllocatePoolWithTagPriority and AllocateCommonBuffer (if the driver's device uses bus-master DMA or a system DMA controller's auto-initialize mode).
Drivers should use the tagged versions of the pool allocation routines instead of the nontagged versions, which are obsolete. WinDbg and numerous testing tools use the tags to track memory allocation. Tagging pool allocations can help you more easily find memory-related bugs.
3.Use memory economically
Nonpaged pool memory is a limited system resource. Drivers should allocate I/O buffers as economically as possible. In general, avoid calling the memory allocation support routines repeatedly to request allocations of less than PAGE_SIZE. If your driver normally uses several related structures together, consider bundling those structures into a single allocation. For example, the SCSI port driver bundles an IRP, a SCSI request block (SRB), and an MDL into a single allocation.
Drivers that use DMA are an exception. If a driver that performs DMA needs several one-page buffers, but the buffers need not be contiguous, it should call AllocateCommonBuffer once for each such buffer. This approach conserves contiguous address space and improves the chances that the memory allocations will succeed.
In addition, consider whether the memory allocation routines you plan to use round the allocation request up to the next page boundary.
If the driver requests fewer than PAGE_SIZE bytes, ExAllocatePoolWithTag allocates the number of bytes requested. If the driver requests PAGE_SIZE or greater bytes, ExAllocatePoolWithTag allocates a page-aligned buffer that is an integral multiple of PAGE_SIZE bytes. Memory allocations of less than PAGE_SIZE do not cross page boundaries and are not necessarily page-aligned; instead, they are aligned on an 8-byte boundary.
AllocateCommonBuffer always allocates at least a page of memory. If the driver requests less than an integral multiple of PAGE_SIZE bytes, the remaining bytes on the last page are inaccessible to the driver.
4.Use lookaside lists
Lookaside lists provide fixed-size, reusable buffers. They are designed for structures that a driver might need to allocate dynamically and in unpredictable numbers.
Lookaside lists can be allocated from paged pool or nonpaged pool. The driver defines the layout and contents of the entries in the list to suit its requirements, and the system maintains list status and adjusts the number of available entries according to demand.
A driver calls ExInitialize[N]PagedLookasideList to set up a lookaside list, ExAllocateFrom[N]PagedLookasideList to allocate an entry in the list, and ExFreeTo[N]PagedLookasideList to free an entry in the list. The head of the list must be allocated from nonpaged memory, even if the list entries themselves are in paged memory.
5.Avoid frequently mapping and unmapping the virtual address space
Frequently mapping and unmapping the virtual address space can decrease performance system-wide because it can result in frequent flushes of the translation lookaside buffer (TLB), a per-processor cache of virtual-to-physical address translations. Each entry in the TLB contains a page table entry (PTE).
Every time the system translates a virtual address that references a new page, it adds an entry to the TLB. Once the TLB is full, the system must drop an existing entry every time it must add a new entry. Subsequently, each time a caller remaps or unmaps the address space, thus changing a PTE, the system must interrupt all CPUs so that it can update any TLB entries that contain the PTE.
Internally, the I/O manager avoids this problem for the MDL in Irp->MdlAddress . The first time a kernel-mode component calls MmGetSystemAddressForMdlSafe , the I/O manager stores the system address in the MDL along with the corresponding physical address. When the IRP returns to the I/O manager after completion,, the I/O manager unmaps the MDL. Thus, the I/O manager requires only a single mapping (and a single virtual to physical address translation) for each I/O request.
The browser hijacking is one of the most commonly used type of online attack in which the attacker or the hacker tried to gain full access of your Internet browser which ever you may be using including the internet Explorer , Mozilla Firefox or even Opera. The attacker tried to change the form and the content while you surf the web. If you keep your computer up to date by installing software and updates with the latest safety and surfing rules respecting the essential security you're already doing much to prevent such attacks. However, if your browser has been hijacked, you can free the pirates and restore its settings in several ways.
How to Identify whether the browser has been hijacked
Among the indices browser hijacking include the following unusual behaviors:
1.The home page or other settings of your computer have been modified.
Example: links to sites that you tend to avoid have been added.
2.When some of the web pages become inaccessible
Including sites of antispyware and other security software.
3.The pop open cascade
The pop open continuously on your screen.
4.New toolbars and favorites have been installed
Displaying icons and links to Web pages side.
5.The computer is slower
Malicious software can slow the operation of your computer.
By following a few simple guidelines you can ensure the proper operation of your computer:
Be extremely careful when you download or installation on your computer
When you download a new program on your computer, a warning message appears, as in the following screenshot. Take this warning seriously. Games and multimedia services dubious online can hide spyware and other malicious software "free" needed to use their services. If you are unsure of the reliability of a program or a software component, do not download and do not install it on your computer. In addition, if you are prompted to allow installation of the program via a popup window, click No, unless you really want to install this program on your new computer.
Download and install protection software
1.Install automatic updates . In Windows 2000 and Windows XP, Updates will get installed automatically installed on your computer. However if you have disabled automatic updates in your computer and hence try it manually, So simply logon to the website Microsoft Update and install the service packs and updates for Windows, especially Windows SP2.
2.Ensure that you are using the newest version of the browser. If you are using Internet Explorer, make sure you use the latest version of the software and download and install all available security updates available.
3.Use antivirus software and antispyware updated. Set them to run automatically. Many browser hijacking attempts are linked to viruses or spyware.
Have a toolkit anti-diversion provision. A tool kit should include anti-diversion programs such as Microsoft Windows AntiSpyware (Beta) (available in English only) and Spybot , which, if misused, will help you to regain control of your browser and your computer. Furthermore, reliable antivirus programs can detect some diversion, sometimes marked as Trojans , and help eradicate them.
Configure the security settings of your browser
1.In the Tools menu, click Internet Options, then click the Security tab.
2.Click the Internet icon on the Custom Level button, then select Medium in the Reset menu.
3.Click the Reset button.
4.Click OK.
Restoring a hijacked browser
To try to restore the settings of your browser, follow the six tips below.
1 - Stop the continued opening of pop
When the pop open continuously on the screen of your computer, you probably want to stop the deluge first. Microsoft Windows XP or Windows 2000 with Internet Explorer, follow these steps:
1.Press CTRL + ALT + DEL, click Task Manager, then click the Processes tab.
2.Click IEXPLORE.EXE, then click the End Process button.
This closes all instances of Internet Explorer. You can then open the program again and surf as usual. To prevent future attacks, activate a program to block pop-ups. To enable the blocking of pop-ups from Internet Explorer:
1.In the Tools menu, click Internet Options, then click the Privacy tab.
2.In the window Pop-up Blocker, click the check box Block pop-ups. Click OK.
If other symptoms persist web browser hijacking, do the following:
2 - Install a program of prevention
As one of those mentioned in the paragraph entitled Skip browser hijacking. Many browser hijacking programs can be detected and removed by running these programs, once downloaded and installed on your computer.
3 - Run the removal tool for malicious software .
It can detect certain types of diversion program, but not all. I recommend you to download the Microsoft Security Essential
4 - Manually restore your settings. If you are using the Internet Explorer browser and your homepage has been changed, you can restore yourself.
1.In the Tools menu, click Internet Options, then click the General tab.
2.In the Start page, enter the desired Internet address in the Address bar, or click the Back button to restore the default setting of the original manufacturer.
3.Click OK.
5 - Remove unwanted programs using the Add or Remove Programs.
If you want to try to eradicate advanced methods, see the article titled Unexplained computer behavior 'may be Caused by deceptive software on the support site and Microsoft support. You can find additional steps, including activities at the Add / Remove programs, delete program integrated, and the search function in Windows Explorer program.
6 - Empty the trash
After all these steps, especially if you have removed an unwanted program. Restart your computer.
Google memperkenalkan fitur baru dalam mesin pencarian. Google menyebutnya sebagai Instant Search. Perubahan ini diperkenalkan untuk membuat pencarian cepat dan interaktif dengan menunjukkan hasil yang seketika saat Anda mengetik. Dengan Google Instan, yang Anda cari telah berubah dari sebuah halaman HTML statis ke aplikasi AJAX, mirip dengan Google Maps dan Gmail. Tapi tidak semua pengguna internet menyukai fitur ini. Banyak alasan mengapa sebagian besar dari Anda ingin menonaktifkannya tetapi yang sangat umum biasanya masalah "kecepatan koneksi internet".
Jadi, jika Anda tidak ingin fitur ini dan ingin mematikannya, cukup membuat perubahan yang diperlukan dengan mengklik link di samping kotak pencarian pada setiap halaman hasil pencarian.
Sebagai contoh, pencarian untuk "Apple" di google dan Anda seharusnya mendapatkan beberapa hasil. Berikutnya Setelah pencarian, Anda akan melihat sebuah link dengan judul "Instan Is On". Klik "Instan Is On" dan kemudian pilih "Off (tekan Enter untuk pencarian)".
During data processing some operating systems use the hard disk as memory, called virtual memory. During processing, operating system transfers some data and programs from RAM to hard disk and reloads again when required. The data or programs are stored in hard disk in temporary file called the swap file. This technique of swapping data between memory and hard disk is called paging. Operating system spends a lot of time in paging process, instead of executing the application software. But the problem is that while working you use different software programs on computer and page file may contain your confidential information or stored in non encrypted format. To reduce this risk, you can set your computer to clear out page file automatically each time you shutdown your computer.
Perform the given steps to set your system clear page file automatically:
To enable this feature, you will need to be logged into your computer with administrative rights.
First click on start button to open control panel and then click here on "Administrative Tools" option.
Now "Local Security Settings" panel will appear, on lift side of this panel click on "Local Policies".
Here click on "Security Options" then double click on "Shutdown: Clear virtual memory pagefile" option.
Now small dialog box will appear with options, "Enabled or Disabled" the page file.
Press Apply button to save settings and then click on Ok button to finish.

Recently, mobile technology has become increasingly sophisticated with the new components, the better chips, and a faster processors. But there’s one part of Laptop or Netbook which is the “Achilles heel” – the battery. Operating systems, modern graphics, and various other advanced application rapacious spend your laptop battery every day. The average laptop battery life remains in the range of 3 – 4 hours. Of course, this is still a problem for workers who often travel long distance.Most effective way at this time is to bring some spare batteries in your trip. But, beside this there are at least a few tricks that can help you to save laptop batteries a long time.
1. Laptop HD defragmentation – Regular defragmentation can help you manage the data to be more efficient and make the hard drive (HD) a little faster to access the data. When HD works quickly, the more you can spare of laptop battery energy.
2. Turn off High Power Applications – Immediately turn off the background process that is not important. Watch energy use through the Windows Task Manager [Ctrl + Alt + Del]. If you are not using the internet, then your laptop is safe to turn off programs that are not that important to work on the taskbar, such as antivirus and firewall. Run – msconfig – Tab: Startup and remove n the programs that you do not want to launch your laptop and reboot once.
3. Suspend the Scheduled Tasks – This process can be defragmentation or virus scan, but make sure you schedule an activity at the time you are near the power source. If not, delay or combine alternately between them, to find the time and place to fill the battery.
4. Unplug External Tools – Tools that use the USB can spent battery power. After use, do notforget to pull out all the external equipment such as mouse, PC card, Wi-Fi, an external speaker, Bluetooth, and even an iPod or iPhone.
5. Clear Drive CD / DVD – Do not leave a CD / DVD any left in the laptop if it is not used.
6. Use Local Hardware Equipment – Try not to use an external DVD or other equipment
7. Remove lights – LCD laptop screen is also one of a battery waster. Configure light level to the lowest level that you can still see by using the Function or use the Display Settings in Control Panel.
8. Turn off Voters – Turn off the speaker and avoid the use of multimedia software. Sound scheme also spent laptop battery.
9. Do not Use a Screensaver
10. Visit the Power Options – Know energy management / power through the application “Power Options” in Control Panel. Both XP and Vista have this advanced feature to turn off components such as monitors and / or HD after specific intervals. “Max Battery” in the Power schemes can be chosen to maximize battery life time.
11. Use classic style GUI – On Vista, click on the “Desktop – Preferences – Color View – Appearance – Appearance Classic and Basic Windows graphical interface.” On XP, “Display Properties – Theme – Windows Classic”. Linux and Mac have a better system in this case to maintain the battery.
12. Hibernate is Better of Sleep – On the Stand By mode (or Sleep Mode), the computer will shut off and the HD display but the memory remains active while the CPU slowed. This is of course the battery. Meanwhile, hibernate is better because laptop save all of the conditions and the last off the total to save energy.
13. Do not run a lot of programs simultaneously – Working with many programs, of course, require more energy. We recommend using only one or two programs you really need at the same time.
14. Use More RAM – A large capacity RAM can reduce the burden of virtual memory that directly lead to effects on the HD and also lead to spent laptop battery life.
15. Maintain Hygiene of Your Laptop – Laptops with the dirty air ventilation will be greater heat and with that spent battery (ventilator always work). Clean the air vents on a regular basis to maintain the temperature remains the minimum. Leave the area around the ventilation as much as possible open or empty for easy air circulation.
16. Avoid Places with High Temperature – As much as possible avoid direct sunlight or other heat places.
17. Avoid Memory Effect – The battery type Li-Ion does not have this problem. This problem may increase for the battery type Ni-MH. This can be prevented with a charge when the battery is completely empty.
18. Update Software and Drivers – Usually, the drivers and the latest software is designed to work more efficiently than the previous version.
19. Use the Right Adapter – Make sure that you use to adapter for your of the original specification or match. The wrong type can lead to overload and damage the battery and your laptop.
20. Trim Laptops – If you don’t use laptop some time, make sure that the laptop is 40% filled, pull the battery, and store in some dark place.
1. First – click Start then Run and type “regedit” without quotes and press Enter
2. Go to My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify. In this location delete the folder “WgaLogon” and all content with name WgaLogon. If there is no WgaLogon folder continue with next steps.
3. Restart your computer. After restart WGA will not be active and you can remove it completely following the next steps:
4. Set your folders options to show hidden and protected Windows files – go to My Computer/Tools/Folder Options and then choose View. From the View tab choose “Show hidden files and folders” and uncheck “Hide protected operating system files” and click OK
5. Now, Go to folder Windows\System32\dllcache, find and delete “WgaTray.exe”. Also, check for “WgaTray.exe” in Windows\System32\, and if you find it delete it, and search for “Wga*.*” with Start-Search-All files and folders and delete everything that starts with “Wga” (Wgatray.exe; Wgalogon.dll, Wgasetup; etc..)
6. Restart your computer again and live happy and free.
A wireless network is one that enables the connection of two or more computers together without cables involved. Wi-Fi, was published under the IEEE 802.11 standard, it has been updates, which work at different speeds. The Wireless Local Area Networks, allows highly mobile users, allowing them to minimize the cable connections, using radio frequency technology.
Some Points to Check Before setting up a Wi-Fi :
The wireless devices are sold with all the security turned off, so anyone can connect to the latch and / or damage to: need user intervention to activate the protection.
The security of wireless networks is much weaker than allow the manufacturers of these wireless devices.
The real performance is far lower than those advertised.
I realized my wireless network using devices that follow the 802.11g standard, so these notes are limited to devices that meet this standard. I do not have the actual time to write a treaty is valid for all possible variants of wireless connections. Most of the information given here is independent of the operating system. It is therefore whether you are using Windows, whether you are using Linux, whether you are using Mac or any other computer and operating system.
What you Need
To create a wireless network usually uses a configuration called star. In this each computer connects to a central point, called the access point. There are other trinkets as wireless routers and bridges, which have similar functions, but all will point to simplify them generically as an access point (the experts do not send me too many accidents). The access point is then connected to the wired network and / or the Internet. There are several other ways to connect computers with wireless cards, but I am here.
You can not separate the wired from the wireless network, interposing between the two networks is a hardware or software firewall. The firewall then allows wireless access to the machines to those of the wired network only under certain conditions, you can set to your liking, for example, you can allow access to the Internet via wireless or wired network in your Web server, but not the resources shared (disks and printers).
You can use a standard range of IP addresses. Normally, local networks using addresses in the range 192.168.1.x, where x is between 0 and 254 (there would also be the 255, but it is reserved). The intruder knows, and set your wireless card to use the same range. But if you use another range, the intruder is displaced (not forever, but enough to make his life difficult.) Warning: If your local network is connected to the Internet, you can not use a range of addresses any, why would you go into conflict with the addresses used by the rest of the Internet. The options allowed are 192.168.xx, 10.xxx, and 172.16.0.0 to 172.31.255.255.
Setup
Connect your computer to a local network (Ethernet) or internet either through the use of a standard network card (external or integrated into your motherboard) or using a wireless network card or wireless (WiFi). Must have the data connection if necessary as in other operating systems (IP, DNS, network password, etc..). Create different configuration profiles designed for portable computers that usually connect from different connections.
Connect your PC to phone cable internet through a standard internal or external modem, configuring the connection data (user, password, telephone access, etc..).
Wi-Fi : Each PC you want to use in a wireless network of computers need a wireless network card or a wireless connection. The laptops include more modern wireless connection. As mentioned above, there are several standards for speed and usually are downwards compatible, ie a computer with fast connection can communicate with slower components at the speed of the latter.
Access point (Access point) : Type access points bridge act as switches, allowing users to access the wireless network while establishing connection to wired computer. These are connected with cable to a router or a switch.
Router with access point : These routers perform the same function as the router wired and include a WAN port (Internet) to RJ45, several LAN ports with RJ45 cable to connect to other computers or peripherals and an integrated wireless access point.
Some Points to Take Care :
When installing a wireless network must take certain steps to minimize the risk of a security incident occurs. Thus, access to company information by outsiders, the use of the network for malicious or consumption of bandwidth (with the consequent drop in performance of the company) are possible scenarios in the context of a wireless network.
1. Every network card (wireless or not) has its own serial number, which is called MAC address. The access points can be set to accept connections only from cards that have a certain MAC address. This makes it very difficult to penetrate the intruder in the network, because it must first discover a MAC address allowed. It is not impossible, but it is a hassle that discourages most of the attackers.
2. DHCP is a system that simplifies network management by automatically assigning an IP address to every machine connected to the network. This is handy in a wired environment, but it is dangerous in a wireless environment, because it assigns an IP address automatically even an intruder.
3. The wireless network has its own identifier, called the SSID, the wireless cards are able themselves to know to connect. Even the intruder needs to know to do his dirty work. The trouble is that I know is simple: most wireless devices is set at the factory to use, such as SSID, the name of the manufacturer. Another nice tricks. Since manufacturers are not so, it's trivial for an intruder to one.
4. WEP is a sieve, but is still in its little more to interpose a barrier between your network and intruders. It should therefore be operated with all other countermeasures, and the highest possible level (usually 128 bits), but beware: do not use any predefined keys.
Many times when our computer is affected by malicious files or virus files, they tend to affect document files such as excel, word, powerpoint etc. At such situation, we don't have any other alternative but to delete or remove infected files from the computer hard disk drive. There is no possible way to recover corrupt file of Microsoft PowerPoint. The PowerPoint open files also tends to get corrupted while trying to save or while working on it and also during PowerPoint application or as when windows operating system gets crashed due to some unavoidable reasons. At such senario, Windows operating system try to save a duplicate copy of work file like a temporary version. In this type there is no requirement of installation of a third party software in order to arrange corrupt files, as you are able to recover it from TEMP folder.
Steps To Recover Corrupt Microsoft PowerPoint Files:
* Initailly click on Start button and then click on Search option to start search process.
* Inside the search text box, type *.TMP and then select the Local Hard Drives option in "Look in" box option available.
* Then just click on Search button in order to start the search process of temporary files available inside your system local drives.
* As search finishes taking some time, windows system will display a list to temporary files available.
* Try to manage all the temp files as per Date modified pattern.
* As you are able to view that file, open it with the PowerPoint application and open the temp files by double clicking on file in order to run in PowerPoint.
