Hello. The only program that is able to access internet is internet explorer. Mozilla is completely blank when i start it, it won't even try to open the home page. Opera can't access internet, but it will try to do so. Bittorrent won't download anything. Before i was able to use it by reinstalling it, every time i shut my computer down. That does not work anymore. AVG is unable to download updates. Spybot can't be installed, as the installation program is unable to access internet. iTunes can't access internet. I've tried reseting the TCP/IP settings, and i've disabeled all firewalls. I also uninstalled the Norton antivirus software that came with the computer. I would be very grateful if someone could find the solution to my problems.
