Hotbar and DSO exploit

i've ben working on a PC installed with XP Home. There is something on it that exploit the DSO exploit in Internet Explorer. I can find it with Spybot Search and Destroy but I can't seem to get rid of it. Every time I use Spybot, the problem goes away and I can launch Internet Explorer. But if i reboot the computer, I can't launch IE. If I run Spybot again, the DSO is found again. Strange. I tried turning off System Restore and updating everything but no luck. As long as the computer is on, IE works fine.

Also I can't get rid of the Hotbar folder in c:\program files. Launching IE will always create the folder.

Any help is appreciated.
