Hi there
I suggest you uninstall About Buster for the time being. You can discuss it's merits with one of the technical guys here if you like but I don't recall seeing a large number of folks in this forum using it. Everyone around here pretty much uses Spybot, Spyguard, Adaware etc. If you don't have CWShredder and Hijack this, click on the link below and download them. Run CWShredder and Hijack this. Come back and post the log from Hijack this in here. I'm sure one of the Techies will analyse it and get you sorted out.

Let me know if you get sorted out
