Sounds like a nested virus.
Give these a shot:
FREE One-Care Safety Scanner (Online mode, might not delete the viruses, but it tells you where they're located at, so you can go delete them yourself.)

AVG Anti-Rootkit Free:

I recommend you use all these scanners, in order as posted. The two at the top are both Anti-Virus scanners, however one of the two might find something the other hasn't. Just remember, don't run two scans at the same time. Make sure to let the previous scanner finish before launching the next one.
The two scanners at the bottom are anti-spyware/malware and anti-rootkit scanners. The reason for using them both is obvious. Firstly, spyware and malware can sometimes open the door for downloading more malicious files, such as viruses or trojans. Secondly, rootkits are typically the file that downloaded the infectious files to your system. These nasty hidden files will re-download the virus after it has been eliminated. And since not all anti-virus scanners can detect them, they're free to roam your computer as they please.
So, once again. Run the scans in order as posted here remembering to run the scans one at a time. Hopefully this solves some of your problems, if not all of them.
