This question already has an answer here:
I think a netbook I'm tasked with getting back into shape might have the Vundo/Virtumonde virus. I've run MS Security Essentials, Malwarebytes and Spybot but it's not spotting it.
I know this is a hard one to detect (and harder to remove). Before I go through the hassle of ordering system restore CDs (or just putting Ubuntu on this thing and being done with it) I wanted to be sure it, indeed, has this virus. Is there a spyware/anti-virus/malware app that is known to be able to detect the Vundo virus?
