I am using XP SP2, and everything where working fine. Somehow I can go to some web pages, but I can't login to them, for example
www.buzzerbeater.com, I can't access my Hotmail / Windows Live, Outlook doesn't work either, also
www.realgm.com, I can't access the forums too. I have tried with IE7 / Firefox / Chrome, but same result. I was using avast free edition that I removed, and I don't have any other security software installed.
My laptop from the same network works perfectly. Any ideas?
