Hey man.. I had that shit a whilE back and it took me about 2 days too get rid of it.
start here...
http://www.symantec.com/business/sec...112210-3747-99
run both tools (unless you know which vundo you have)
reboot in safe mode, run the tool again
reboot in safe mode run Windows Defender...
http://www.microsoft.com/windows/pro...r/default.mspx
reboot in safe mode run spybot search and destroy.
reboot in safe mode and go through each item that runs on start up, run each item 1 at a time, if you dont know the process, do not allow it to run
Run the symantec program again
reboot normal and run all 3 programs again
Cross your fingers and good luck. I had to repeat this process several times until I found all files that were auto running and reinstalling the malware
