Hijacked--Need Help

Unknown

I have tried everything. I have run Spybot, Ad-Aware, etc. I DLed FireFox and am using that now instead of IE. I also followed the "Home Search Assistant Removal Guide" and it didn't entirely work--a lot of files are gone now...but crazywinnings and IST just don't want to leave...what should I do? Here is my HJT log:
