The other option is to reset your browser to the default settings.
Assuming you're using IE, go to Tools, then Internet Options, then click the Advanced tab. Next go ahead and hit the Reset button (Reset Internet Explorer Settings.) This will wipe away any changes (postive or negative) and will reset your browser as if it were Day 1 again. You will have to reset your settings as you go, but the redirect should stop.
If it's worth doing, it's worth doing right.
