Norton is being blocked by a virus (suspicious.vundo.2 detected)

Norton will not run, neither will malwarbytes.  The last message I got was threat detected from Norton suspicious.vundo.2.  I was trying to download a program and I am assuming that I downloaded a virus.  I had a virus before and was told it was a root kit.  I still have the program that I was given to scan the computer (GMER).  I will run a scan with it and post here.
