Sounds like some of the fake antivirus ones that don't let you log into major websites.
All other websites work, just facebook doesn't work, at first it brings me to some fake facebook page and when you login, it shows you some random stuff. After a while, when i type facebook.com, it comes out a warning saying that there is a virus thing on it. Now when i type facebook.com, a blank screen comes out.
Anyone bored? Verify my paypal for me, just add me on msn
