How do you get rid of a computer virus which does not allow the computer to start pass f8 and keeps restarting itself?

Answer 1

These steps will correct most infections, it may not correct all of them. Use this at your own risk. First step is to locate a Windows XP CD that matches your computer, either Home or Professional, depending on what is installed on your computer. The first technique is to boot from the CD, select the option of Repair. If you get the choice of the recovery console or the emergency repair, select the recovery console. Newer versions do not include emercency repair and will only offer the recovery console. It will then show you the OS you wish to repair, most computers will only show you one option. Select the OS. It will ask for the Administrator password. In all likelyhood, it is blank, so just press enter. If someone has set up a SAFE MODE administrator password, you will need to know it or this will not work. Once the command prompt is present, enter the following command. chkdsk /p This will check the volume for errors and force it to fix any errors it finds. When complete, read the report and look for the statement "One or more errors were found" statement. If this statement is not present, your disk is healthy. If one or more errors were found, repeat the chkdsk /p command. If errors are found the second time through, try chkdsk /r to try to salvate the disk. If errors are reported on three consecutive chkdsk commands, the disk is failing. Replace it or seek the help of a professional. Provided the disk is now clean, from the command prompt, type FIXBOOT, and answer yes to the prompt, then FIXMBR and answer the promt yes. Now try to reboot. If it still fails, follow the procedure below. Boot from the CD. When the main menu appears, select to install windows. Accept the user agreement. (F8), now listen carefully to this advice. Windows will examine the drive and try to find a valid OS installation. If it finds a valid Windows, it will give you the option to REPAIR the installation. If this is the case, go ahead and repair it. Most of the time this will work and you will simply have to re-install all Windows Updates, as it will have reverted to the patch state of the CD. Make sure to run Windows Updates till there are no more updates. If the installation does NOT FIND A VALID OS, you need to pull the plug and get help from a pro. If you ignore this advice, you will erase your old hard drive and lose whatever you had saved there. Good luck
