How to do stop the popup message for upgrading to pro version? It's so annoying that i am about to uninstall agv and use a different AV.
When I launched the AVG Protection, I get a message saying  "Your PRO trial version has expired" and I cannot access any of the AVG settings.
Did a bit a search online and came across this article:

I went for Option 1 and after installing the free version on top of my already expired PRO version , I got the same annoying message.
Can anyone help?
