Problem after Avast upgrade
Today I upgraded Avast to the paid Avast Internet Security version. After installation Firefox browser won't open. Actually Firefox opens but can't load any pages. Just a message saying can't load page, check spelling, firewall settings, network connection, etc. I did a system restore and am back to the free Avast and all is fine. It is probably a setting but I can't find what changed or needs to be changed. Any ideas? Thank you.
