Why is the Avira Firewall temporarily disabled on my computer?

We are aware that a recent update of Avira has caused an issue for some Windows 10 and Windows 11 users. The issue is caused by the Avira internal Firewall under a rare condition. It results in new Windows processes not being started.

The issue was automatically fixed by an update deployed on Monday, Dec 11, 11:30 AM (CET). This update will temporarily turn off the Avira firewall until a complete fix is ready.

There is no impact on security as Avira Antivirus is enabled to provide protection.
