Rollingthunder,
Did you run Ad-Aware?
It will let you remove Malware on the next bootup of your system. (If files are in use, they cannot be removed and that is why it will remove them on the next bootup.)
Take Care,
Richard
P.S. 100+ Viruses/Worms is not good. If any of them are destructive, it might be time to get a friend that knows about computers to do a fresh install of WinXP for you.
