First thing to try is CWShredder
http://www.spywareinfo.com/~merijn/files/CWShredder.exe
If that fails use HijackThis
http://www.spychecker.com/program/hijackthis.html
If you can't figure out HJT then post the log from it and I'll tell you
what to checkmark and delete.
Be fast though I ain't gonna hang around here all day.
