Virus re-post?

I use Mozilla Firefox and I have gotten The Trojan horseDownloader.delf.12.ag virus. Spybot doesn't seem to take care of it, and I think I got it from using AVG,BECAUSE SPYBOT ACTUALLY REMOVED BAD THINGS FROM AVG! Does anyone know a site that has free software that can get this crap off my p.c. without downloading more of it that's hidden in a anti-virus file?

instead of half removing a virus why not just reinstall windows? its alot quicker and you know for a fact you have no remaining virus'
