Welcome to Safer Networking, I wish to be sure you have viewed and understand this information.
"BEFORE you POST" (READ this Procedure before Requesting Assistance) http://forums.spybot.info/showthread.php?t=288
All advice given is taken at your own risk.
Please make sure you have read this information so we are on the same page.

This machine needs to be formatted.

This system is infected with a polymorphic file infector called Virut. Virut is capable of infecting all the machine's executable files (.exe) and screensaver files (.scr). However, the problem is that the virus has a number of bugs in its code, and as a result, it may misinfect a proportion of executable files and therefore, the files are corrupted beyond repair. As of now, security experts suggest that a format and clean install, or destructive recovery if you have an OEM recovery partition, is the best way to clean the infection and it is the best and safest way to return the machine to its normal working state.

Backup all your documents and important items (personal data, work documents, etc) only. DO NOT backup any executable files (softwares) and screensavers (*.scr). It attempts to infect any accessed .exe or .scr files by appending itself to the executable.

Also, avoid backing up compressed files (zip/cab/rar) files that have .exe or .scr files inside them. Virut can penetrate and infect .exe files inside compressed files too.

Recent variants also modify htm, html, asp and php files.

Do not back up to another machine, as it may become compromised. Burn to DVD/CD, or to an external drive which has nothing else on it, and which you can format should it happen to become infected from the backups.
