Adware.generic

I've got a machine that I "inherited" from a previous admin and it has apparently never been updated with virtually any Windows Updates, much less service packs. I have scanned it with AVG Anti-Spyware and about all it comes up with is "adware.generic" which I tell it to clean. Unfortunately it doesn't remove it permanently, because I can then do another scan and it'll pop right back up in the scan results.

Here's my HJT log:

I'm wondering if there is spyware or something blocking service pack updates because I can't even install service packs. :-(
