Hello Barry,
We will help you sort it out. I request you to change AVG Firewall network profile to private (open AVG Internet Security > menu > settings > components > firewall > customize > network profile > change all the network public to private), please go to Firewall customize settings again > scroll down > click on system rules > enable all the system rules if it's not configured, click OK and check if you can access network (KVM software) with enabled AVG Internet Security.
There is an exception set for all networks for TCP/UDP on all ports (out) and the default 31234 (in). This worked fine until I upgraded to AVG Ultimate (exceptions are in Windows 10 Firewall for Input Director) - now it cannot find the slave pc which has AVG Firewall on. If I turn off AVG Firewall, it works ok. For info: when AVG Firewall is turned off, is Win 10 Firewall enabled?
