Have recently renewed AVG on 2 computers. Have tried to install Adobe Flash Player on both and keep getting message "Note your antivirus software must allow you to install software" What do I have to change in AVG to allow software installation?

Anthony, Try disabling AVG to allow the Adobe install… Have a look @ this article (https://support.avg.com/SupportArticleView?urlname=How-to-disable-AVG). Don't see a problem with Community webpage.

Both computers are coming up with this issue with loading Flash Player.

Also both computers cannot display the https://community.avg.com/homepage and come up with the "Internet explorer cannot display the webpage" "Diagnose connection problems" so I actually have to use a different computer to logon and use the AVG help.

Any Ideas
