The DSO Exploit vulnerability can be corrected in the registry fairly easily, but I don't have time to put up instructions right now. I have to go to work.
If anyone wants I can post instructions this afternoon. I would need to know the exact registry keys that are flagged by SpyBot (and there may be multiple entries).
The slightly less common "Possible Browser Hijack" flag in SpyBot that it can't fix can also be corrected in the registry.
