How do I remove a computer virus?

This question is a very simple question for you, go through this articles,

This information applies to Windows Internet Explorer 7 and Windows Internet Explorer 8.

Here are a few things you can try to remove a computer virus:

Keep your antivirus program up to date. If you have already installed an antivirus program on your computer, it's important that you keep it up to date. Because new viruses are being written all the time, most antivirus programs are updated frequently. Check your antivirus program's documentation or visit their website to learn how to receive updates. Be aware that some viruses block common antivirus websites, making it so you cannot go to the website to download antivirus updates. If this happens, check with your antivirus vendor to see if they have a disc you can use to install the latest updates. It might be possible for you to create this disc on a computer that is not infected (for example, on a friend's computer).

Use an online scanner. If you don't have antivirus software installed, visit the Windows Vista Security Software Providers website for more information about security and virus prevention. Some of the partner sites offer free online scanners which will search your computer for the latest viruses. These scanners will not protect you from getting a virus, but they can help find and remove viruses your computer already has.

Stop a runaway virus. Viruses are often created specifically to take control of your computer and send copies of themselves from your computer to other computers. You can usually tell this is happening if your computer is performing slowly and accessing the network more frequently than normal. If this is happening, you should disconnect from the Internet and network (if you're on one). If you are connected to the Internet through a physical connection, disconnect the network or phone cable from your computer. If you're connected to the Internet through a wireless connection on a laptop, turn off the wireless adapter on the computer (either by turning off a switch or removing your wireless adapter card). Once your computer is disconnected from the Internet, run your antivirus software (from a disc or software on your computer) to remove the virus.

Manually remove viruses. Sometimes a virus must be removed manually. This is often a technical process and should only be attempted by computer users who have experience with the Windows registry and who know how to view and delete system and program files in Windows.

The first step is to identify the virus. Run your antivirus software to identify the name of the virus. If you don't have an antivirus program, or if your program does not detect the virus, you can still identify the virus by looking for clues about how it behaves. Write down the text in any messages displayed by the virus or, if you received the virus in e‑mail, write down the subject line or name of the file attached to the message. Search the antivirus vendor's website for references to those specific things you wrote down to try to find the name of the virus and instructions for how to remove it.

Ok, my virus is gone, now what? Once a virus is removed, you might have to reinstall some software, or restore lost information. Doing regular backups can go a long way toward easing the pain of a virus attack. If you haven't kept backups, start now.
