Repeating antivirus message

System got infected  and I ran a full scan along with the Norton Eraser tool but nothing seems to work. Norton antivirus indicates that the virus was "quarantined" but it seems like it keeps installing the file in different location.

Trojan.Gen ,  Trojan.Gen.2, and Trojan.zeroaccess.B are the files.

 

I have a Vista, 32-bit w/ SP2.

 

Thanks for the help.
