Latest Avast Internet Security not working with Windows 10 Creator

I have an up-to-date subscription to Avast Internet Security and in the past few days I have upgraded to Windows 10 Creator. I notice that when I boot up after about 30 sec to 1 minute the internet will disconnect. In order to fix it I have found if I turn off Avast Internet Security Firewall it will return to normal. Everything was working fine before the upgrade.

Has anyone experienced this? Is there a known permanent fix?

I’m having this exact same problem on all three PC’s I have it installed on. 2 connect via wireless and one wired.
Beyond frustrating.

As already has been told in many other threads, there is a bug in the port scanner.
Disable it till have avast has rolled out a fix for it.
