Since a recent Avast upgrade to Premier, the Avast firewall is blocking access to my 192.168.1.xxx addresses. I can't access my network printer and my network server for backups. After a day of debugging, I traced the problem to PORT SCAN DETECTION in advanced settings for the firewall being turned on. If I tun it off everything runs normally. This is new behavior. I am on Premier version 17.3.2291 (build 17.3.3443.0) and Windows 10 Version 1607 (build 14393.969).
Is anyone else seeing this. I did a search and did not get any useful hits.
