If a firewall or proxy is active in the network and there are problems updating Avira Antivirus Pro or Avira Antivirus Server, as well as the Avira Mirror, certain exceptions should be set.

Please set the following exceptions:

  • prod.update-bridge.avira.net with Port 443
  • *.avira.com
  • *.avira-update.com
  • *.cloudfront.net
  • api.mixpanel.com

The update servers are accessible via port 80.

IP addresses cannot be added for the update due to the CDN used having different, changing IP addresses.
