Trojan.GrandStreet

I've run spybot S & D, NAV, and AdAware but can't seem to remove Trojan.GrandStreet. Teatimer blocks Trojan.GrandStreet from modifying the registry but it does not kill this malware. Every time I start IE Trojan.GrandStreet is triggered and tries to download more malware. Any suggestions on how to proceed?
