After new upgrade (4/21/2017), some previous apps that can access internet are blocked out.  When try to add a new app via the application rule, AVG pretends to add the app, but really does not add.  At least, when I try to follow the displays on the screen, no apps are added via application rule.
What are the real steps?  Why it not works?  I can also not able to delete app group.
If I can not get apps to access the internet, then eventually, I would need to shut down AVG firewall component, and use another firewall, which is cumbersome, because there are a bunch of rules already defined.
Really, with this last AVG update, computer slow down considerably, up till a point that it is not productive at all.
Please help
