I just won a hard fought battle with a virus or two, and the best I mean BEST advice I can give you is go to www.geekstogo.com, look for "hijack logs go here " or something similar, listen to what these people tell you to do, it may take a while for someone gets to your thread but someone will answer you and will absoultly clean your computer of all the problems and fix a bunch of things that you didnt know were broken...
geekstogo.com....accept no substitutes
you will need to download "hijackthis" and post the log it produces..look on GTG to find it
