I would like to suggest that AVG implement a means of blocking all international ip traffic with the firewall. Yeah, I know I can block a range of ip addresses, but, this is tedious and the international ip addresses won't change much. Thus, it should be a simple means to block ip addresses from specific countries by a simple selection/check box means. I can do this with the firewall on my Synology Nas, so, know that it is feasible.
Also, they could implement a means of importing a ip addresses or address ranges to block from a simple text file. With this I could simply make one text file of all address ranges I want to block and import them into the firewall settings. Again, I can do this with my Synology NAS, so, it is possible to implement.
