I have been using PrivateFirewall for a long time and it works perfectly for me.
When I recently changed my AV from AVG 2015 Free to Avast Free, the number of FW logs increased enormously. On checking the Local IP`s they are all private addresses to do with the Internet. My FW blocks them. If I rate these IP`s as "trusted", it reduces the number of logs, but as the Remote IP`s often differ for the same Local IP`s, the logs keep coming.
Why did this happen when I changed my AV to Avast and how can I stop it ?
