How to Remove a Boot Sector Virus
Has your computer been acting strange lately? Has it been running slow, or telling you that your computer needs a certain program? If so it may have a virus. This article deals with ones called Boot Sector Viruses. These reside in the sectors that are used to start your Operating System. A simple operating system replacement may leave the virus to continue its evil ways.
Steps

Remove any important files and shut down the infected computer. You can not begin to remove the virus if it is in the RAM in your computer.

Option 1: Take the drive to a pro. UNPLUG the computer, and all monitors, etc. Remove the HDD (hard disk drive or hard drive) from the infected computer. Be sure to remove all of the static electricity from your self by touching the metal case.

Option 2: Use software on a CD-ROM or floppy (yes, you can still download recovery tools as floppy images) to scan the drive and fix the MBR. Start with the OS install CD. Use the Windows Recovery Console option if you are using Windows XP.

To change the boot order: Enter BIOS via appropriate startup key for your computer. When the BIOS setup page shows, set the CD or floppy drive to boot first.

Sources of that software: Find out which company manufactures your HDD and see if they have a utility that will do a low-level format. This part is important because it deletes everything from your hard drive so that no one can get it back, including the virus. Some common HDD manufacturers' tools for doing this can be found here.

Run the formatting utility provided by your HDD manufacturer.

If you have errors booting the OS, reinstall your operating system of choice however you want to.

And the most important thing is that you use trusted software to remove the virus or else you will be in more trouble (if that software is infected). Some software will show many virus 'hits' in order to sell the full version, so read reviews first.

What's your reaction?
