Cannot access Internet Explorer, iTunes Store, Windows Updates. Why?


Have reinstalled IE8 & iTunes but cannot access IE. 2 phone calls to Webroot support have not resolved the problem. Only Firefox' firewall is on. Any ideas?

Firefox does not contain a firewall and can not block other programs. You may have a firewall running that is blocking access. You could run the free enumprocess application which aims to detect if any firewalls are running, it is available from http://www.trolly.homepage.t-online.de/tools.html

Thanks Tony,

It was my error; I should have listed the firewall as Webroot (not Firefox). I'll check to see if another firewall is running.
