The people who write these virus programs are just plain ol' evil!!!
I got a trojan on my work computer yesterday that couldn't be deleted or cleaned. I contacted my virus software support & they ran a Dos cleaning utility & I'm good to go now. I never had that happen before!
I hate 'em, too! I got to antivirus.com and find their DOS based cleaners to use. Knock on wood, I basically have to clean other folks computers. I keep anti-virus, firewall, and spyware software running all the time on mine to block the suckers.
