Win32 Vundo Removal

I have a virus/trojan on my computer called “Trojan Vundo” and my Norton anti-virus can’t seem to get rid of it! I’ve tried downloading the patch from symantec but it doesn’t seem to pick up the virus. I think thats because its meant for Windows XP, not vista.
Its $189 to get it done by a pro where i am and i can’t afford it! Anyone had this virus/has suggestions on how to get rid of it?
