Why does my Avira Antivirus no longer perform updates?

On rare occasions, Avira Antivirus may no longer update manually nor automatically. This is caused by the RebootPending.txt file which remains permanently in the installation directory of Avira Antivirus even after a computer restart.

Consequently, the computer expects to restart again after the startup and therefore blocks the automatic updates of the antivirus program.

Deleting the RebootPending.txt file allows the Avia antivirus to perform automatic updates as expected.

1. Click the Avira icon in the system tray to open the Avira user interface.
2. Click Security in the left menu.
3. Click the module Protection options.
4. Click the settings icon of the System protection.
5. Click General → Security.
6. Disable the option Protect files and registry entries from manipulation.
   
   
7. Confirm the change by clicking Apply and OK.
8. Delete the RebootPending.txt file from the following Avira Directory:
   
   
   • Windows 10:C:\ProgramData\Avira\Antivirus\CONFIG\RebootPending.txt
   • Windows 8/8.1:C:\ProgramData\Avira\Antivirus\CONFIG\RebootPending.txt
   • Windows 7:C:\ProgramData\Avira\AntiVir Desktop\CONFIG\RebootPending.txt
   
   

   Note
   If the "Application Data" or "ProgramData" folder is not visible, activate the option “Show hidden files, folders and drives” in File explorer.
