Outside of the actual browser, under your settings file, there should be an Internet Settings button. It should look identical to the one in your browser, but it works outside of it. I had a similiar problem about a month ago, and was spitting nails trying to change it. I finally uncovered that, and it allowed me to reset my home page. The downside is that my settings in the browser still won't work.

Run ad-aware 6.0 by Lava Soft, as well as Spybot. Both are free, and will nix just about anything out there. What one doesn't catch, the other often does. I usually run mine about twice a week. Even with a pop up killer, I still get crap that sneaks through.
