My internet network connection is weird

Ok i have internet connetion and all and internet explorer works fine. Any other programs i try to use says i dont have any internet connection at all. Here are a couple of examples. I recently brought starcraft 2 and when i try to install it, it said that im not currently connected to the internet. I downloaded Firefox. Same problems, it says unable to connect when clearly internet explorer works. Even my network setting says that im currently conneted to the internet. I tried allowing programs through my firewall and that didnt work. Firefox says that there's something wrong with my firewall or proxy. I tried alot of thing but i hope you guys have an answer.

whats your Anti virus software?

I uninstalled norton but i still see it around. So yea norton is my Anti virus software

When Norton is uninstalled improperly or the installation becomes corrupted, somehow the program can completely disable certain services and registry values on your computer. I had a customer come in one time and his installation of Norton was corrupted and could not be removed via Programs and features. It would not allow him to connect to the internet, disabled his onboard NIC almost completely and was causing havoc as seen in the event viewer.

I used this tool: Download and run the Norton Removal Tool to uninstall your Norton product | Norton Support and solved all his issues. I've never cared for Norton much, especially the systemworks program.

Hope this helps.

Plus 1 for Devoldo! Notron removal Tool is a must for inunstalling Norton.
