I have set up my Avast to notify me when a new automatic firewall rule is created in Avast Firewall. I've been using this since I bought AIS 5 and it worked fine in earlier versions. But since v5.0.677 it keeps popping up all the time with a new rule has been created, for eg. Microsoft Outlook.
I really doubt Avast needs to create 20 rules for Outlook all the time.
