DSO Exploit

I would appreciate some help on this.

I have Spybot on my PC and it found something it called a "DSO Exploit". The problem is when I tell it to fix it it is unable to remove the five objects they always are there again when I reboot. The five objects are registry changes of some sort that I can tell.

The reason I ran this when I boot up my PC now the "Search Assistant" for the taskbar now always is checked and active. I also have a new tab in my IE called "Main Links". I am trying to find out why this is happening and remove/fix it.

I have Hijackthis and ran a scan. Here is the log file:
