Getting rid of Shazaa.com hijacking?

I downloaded a Matrix screensaver from download.com (http://download.com.com/3000-2390-10264600.html?tag=lst-0-1) When I installed it my homepage was changed to shazaa.com. I ran spybot and Adaware and neither did anything.

Now, I admit I'm not exactly knowledgable about windows registry but I did find the values with Shazaa in them. However, when I deleted them and clicked IE to change my browser back I was sent to a website that opened my cd drives and redownloaded what I'd deleted.

I don't have any *.hta files coming up when I search. I deleted the .exe off of my computer. It all seems to be in the registry now, and I just don't know what to remove and what not to remove. Thanks for any help in advance.
