You defined in your group policy that your firewall should be disabled.
However, after installing several Avira products the Windows operating system loads the default configuration of Windows Firewall.
The reason, therefore, is that the start of the service "NLA (Network Location Awareness)" takes too long. In that case, Windows loads the default firewall configuration instead of the settings you define.
- To fix this, go to the Windows service management: Start → Run → services.msc
- Locate the service "NLA (Network Location Awareness)" or "Network Location Awareness (NLA)." Go with a right mouse click on the Properties of the service and then set the startup type to "Automatic".
- After a restart of the Windows operating system, the firewall should work properly.
