LOL!!!!
I love it when people think the only way to get rid of malware is a re-format...
If you have a better way of getting rid this nasty bit of work, i gladly nominate you to try..
The Virut family of viruses uses polymorphism to hide from all anti-virus protection and then it infects executable files. File infection makes it very hard to repair a system that has been infected. The win32:vitro virus injects code in running processes and it hooks the following functions in ntdll.dll which transfers control to the virus every time these function are called:
* NtCreateFile
* NtCreateProcess
* NtCreateProcessEx
* NtOpenFile
* NtQueryInformationProcess
I've tried every AV on this SOB and it just keep coming back. Its spreads like wild fire through your machine. I've given up with Windows, using Ubuntu Live boot to get my docs, etc off it. Then going "Scorched Earth" on this machine
