Instructions for manual uninstallation

A manual uninstallation of the Avira Antivirus should be performed only if a conventional uninstallation via the Windows Control Panel is no longer possible.

  2. Start your computer in Safe Mode. Therefore, reboot your computer and press continuously during restart the F8 key until the “Advanced Boot Options” screen appears. Select Safe Mode and confirm this with Enter

  3. Open the Windows Explorer with the keyboard shortcut Win + E and delete manually all Avira directories available under the program and application files
