Hi, this past few weeks the internet has been giving me troubles beyond my knowledge.

I am connected to the internet, and am able to use many programs on the internet including iexplorer and skype (only 2 I use frequently). My firefox, which is my preferred web browser, stopped working about a week ago. And since patching World of Warcraft today I haven't been able to connect to their servers. I have checked windows firewall, tried running as an administrator and reset my winsock.

The only thing I can think that might be bugging my PC out is, I recently uninstalled an inactive Norton Anti Virus and replaced it with AVG free (a temporary solution!).

Any help would be lovely! Thank you in advance
