Just want to confirm that, in the Network Inspector, when you go to the status/settings of a Network you’re connected to, that the Firewall profile simply mirrors what the Windows setting is for your network. So, if I have a network set to Public on Windows (meaning it treats the network as public and makes your device undiscoverable), that Avast will then mark the network as Untrusted. Likewise, if it’s marked as Private in Windows, Avast will mark it as Trusted.
I don’t use Avast’s Firewall or have it installed.
