I use ZA free firewall v10.2.078.000 +Win7-64 + Avira Free Antivirus. After some programs update attempts ZA blocks their work without any alarm notification, despite of all components of the programs have supertrust level. For example, Skype or VLC player. It looks like ZA training mode doesn't work. I have next settings: Public Zones security - high, Trusted - Medium; Apps. Control: Network Firewall screens all program (Max), DefenseNet - Manual; Microsoft Catalog Utilization Enabled (checkbox - yes)
