3 viruses (looking for Quads!)

So...  I managed to get three at a time.

 

patchep!sys

Trojan.Gen.2.

Trojan.zeroaccess.B.

 

Gen2 is the once causing the most trouble right now (Crashing every so often).

 

I am running Windows 7 Home Premium 64 Bit and I have a flashdrive. 

 

Thanks for your help!
