|Your best bet, is try booting with the Kaspersky Rescue CD found here, which will allow you to scan the infected system without having to boot into Windows: http://support.kaspersky.com/viruse...|
You'll need a blank CD/DVD though, and then will have to burn it with CDburnerXP: http://cdburnerxp.se/en/home. Once it's burned, just restart your computer and tap "F-10", or whichever key it is to take you to the Boot menu, from that menu select your CD drive and press "Enter".
Another option, if you have a Vista install disc, is to try the Recovery console: http://windows.microsoft.com/en-US/... and of course the last is to backup all data using a live Linux CD (and USB flash drive), and then formating your hard drive and reinstalling Vista... To use a live Linux CD, follow the steps below:
To use a live Linux CD, simply, download the .Iso from here: http://www.linuxmint.com/edition.ph...
Burn it to a blank CD if you have one using CDburnerXP: http://cdburnerxp.se/en/home
Once burned, load the disc into your CD-ROM drive and boot the PC, then select "F10" (or whichever key it says to get to the boot menu)
Once at the boot menu, select your CD-Drive, and press "Enter".
It will then pop-up with a few options.. Please let the CD boot itself(Do not click "Install" or anything else), once at the desktop, click on "Menu", then select "Computer". Look for your disk drive in the panel and left click on it. If that doesn't work, try right clicking the drive, and selecting "Mount".
Once mounted you'll see your Windows partition. To get to your Documents/Pictures and other files to back them up click on "Documents & Settings", then whichever your name is (example "Owner".
Then simply back up all your data, and then trying using the recovery disc that came with your PC (if any).
