I've been hijacked and need expert advice!?

When I open the baseball website MLB.com, it switches to a "questionable" website. This only happens with this website. I've downloaded and runa bunch of antispyware stuff and removed a bunch of viruses etc, but the problem remains. Any advice would be gratefully received.

ditto and be sure to add Haute Secure to your browser. Once you clean your hard drive, you don't want to visit those sites that will add spyware. Haute Secure will warn you of those sites.
hey it sure does sound like a hi jack just clean out your cache and remove all that downloaded crap. it sounds like from my experience the site is putting all kinds of Malware into your system. Merry Christmas
