You have configured in your Group Policy that your firewall should be disabled.
However, after installing several Avira products you find that the Windows operating system still loads the default Windows Firewall configuration.
This is because it takes too long to start the service “NLA (Network Location Awareness)” service. As a result, Windows loads the default firewall configuration instead of the settings you define.
Modify the configuration
- Go to Windows Service app: Start → Run → services.msc
- Locate the service “NLA (Network Location Awareness)” or “Network Location Awareness (NLA).” Right-click the service name and click Properties, then set the startup type to “Automatic”.
- After restarting Windows, the firewall should work correctly.
