I have determined that a computer I am working on is infected w/ gophersearch. I have removed the changed registry entries and deleted the "c:\windows\system\tb22.dll." I would appreciate any help on determining any more threats to this system. I have run 3 or 4 spyware removal programs before this and they have never found or fully removed all of gopgher search. Thanks ahead of time for any help given.
