Try a-Squared, Housecall, AVG, CWShredder, and try posting a Hijack-This! log here and at their forums for assistance. If all else fails, you'll just have to DBAN your computer. //kidding// Also, try CCleaning your computer of all temp files.
What do you use as a browser? What Norton are you using? Up to date? Etc.
EDIT: Oh I already gave this advice. Where is the Hijack-This log? What are you doing online that is giving you all these viruses?
