Quoting a topic that is three years old isn’t wise, too many things have changed not only with avast but more so with the OS versions. So the advice is invalid.
The case now I would say you should disable the windows firewall. I don’t know if win10 would actually disable the windows firewall when another firewall is installed. This could be similar to windows disabling windows defender when a 3rd party antivirus is installed.
