I fail to see how starting a messager program randomly, when VPN is not running, hence revealing your actual IP address to Microsoft and potentially to all your Skype contacts, may contribute to ones security.
Updating programs without allowing selection, therefore running them without user's knowledge, appears to be a default Avast's Free behaviour. Please consider that this may be a serious security risk for everyone running Avast without a firewall and defined firewall rules which explicitely prohibit application access to the Internet behind the VPN.
I expect a comprehensive reply to this post rather than wordless removing of my message from the forum.
