My friend accidently opened the Virtumonde trojan onto my laptop. I have tried Spy Sweeper, Norton Internet Security, and a FixVundo dowload. But none have worked. The download says that the virus isn't on my computer. Spy Sweeper and Norton Internet Security find the virus, restart my computer, delete it. But if I run one of the programs again it finds it again. How do I really get rid of this virus?
