Firewall prevents internet access

Hi Matt, we are really sorry to hear that. Please try these steps to restore internet connectivity ( http://avgread.me/1Fqdu9a ) in your computer. We also request you to reinstall AVG ( http://avgread.me/1bsCjtC ) in your computer to fix the update issue. Thanks.

I have the firewall disabled at the moment, but whenever I have it activated, it will not let me access the internet at all. It won't even let me update avg. 
It's super annoying, can anyone help?
