I think I may have some sort of virus on my computer, but not sure. Anytime I try to look up something on Google or Yahoo, any link I click send me to "Yellow Pages" site and if I hit the back button it send me to some weird search engine site. This is happening on both Firefox and IE. Also, on Google it doesn't let me change my preferences or anything. I've run a couple anti-virus and spyware programs but no luck. Anyone have any ideas? With this and my 360 going belly up I'm having a banner of a weekend!
