Hello!
Where you add/modify the application of Firewall rules in Avast Internet Security ?
at bottom, there are only buttons for sistem rules and rules of the package.
What explains this page:
https://www.avast.com/no-no/faq.php?article=AVKB25
does not correspond with the options shows the firewall settings.
I have installed the latest version, Avast Internet Security v. 12/01/2272 in Windows 10 64b.
Greetings
Jose
