My computer has suddenly started to block random web pages, like ign.com, walmart.com etc ( it will say Error: Unable to find Server). When I search for something on Google, some links works, other's don't. But when I use a proxy (like unlockmyspace.com and others) i can visit all the web pages that were being blocked. This only happens on one of my desktop, the laptop works perfectly. It seems like more web pages are being blocked everyday. I'm using
-Windows XP Pro SP2
-Firefox browser,
-ATT Yahoo DSL.
I tried running an Anti-virus. I use Norton Protection Center, and it hasn't found anything except tracking cookies.
