What ports need to be open for NOD32 to download updates automatically. I added a program rule under windows 7 firewall to allow all ports for egui.exe, but the thing still won't update for me. I have to restore windows 7 default firewall rules, then run update manually. I also set my windows firewall to block all outbound rules except ones with rules created. The only two programs that I need to give access to is firefox (done - 80,443) and nod32 for web scanning (never updates for some reason).
