yea......try bazooka. It works wonders on removing crap that infects IE. I was able to help me remove a couple tihngs off my IE that other programs couldn't find.
the problem with some of these spywares is that it changes/adds certain registry keys so that most detectors think its part of the program. Its mosk likely u have a bunch of .DLLs floating around infecting your IE.
Also, if u have win XP, and you havent done much worh with your computer recently, just do a system restore to a date when u think your comp was clean. I think a lot of people here know that im a full supporter of system restore and everynoe whould know about it =P
