I have the free version of Avast One installed on a desktop running Windows 7; is there a way to close individual ports? it seems strange that the Avast One firewall wouldn’t have such a basic feature but I don’t see how it. There generally appear to be very few customization options; I can block apps and devices and that seems to be it. Am I missing something? If not, is there some way I can turn off the Avast One firewall and use the Windows firewall with Avast instead?
