OK, Now I'm MORE Pissed

Somehow, some bastard program changed my homepage to a f&$^ing search page titled "The Best SE." OK fine, I fixed that, and put back my original home page. But now every time I try to access Google.com I get that goddammed page, and it shows "http://google.com" in the address window. I cannot get to Google from my machine, and I don't know how to get rid of the f*%^ing program that isn't allowing me to get there.

Anybody know how to defeat this?
