Avira Antivir - Error loading system components

After launching an update of AntiVir, you get this message:
Error loading system components: update process has been completed. 


The main reason is that the Avira update sub-processes can not run properly. It's rarely due to the fact that Avira servers have failed.


Check your firewall

For those using a firewall such as ZoneAlarm or COMODO, the Update.exe process is sometimes badly identified

update.exe is known to have four other instance:
  • Spyware Doctor Smart Update
    • update.exe is a process belonging to Spyware Doctor Internet Security ...
  • AntiVir Security Antivirus Updater
    • update.exe is a process belonging to Avira Internet Security Suite
  • Adware.W32.RapidBlaster
    • update.exe is a process belonging to an advertising program.
  • Adware.W32.BargainBuddy
    • update.exe is a process belonging to an advertising program.

So you must go into the configuration page of your firewall and allow the program to modify the registry and/or write files.

Conflict with ither Antivirus

In fact, if you have other antivirus installed, then the update.exe may have been detected as being a virus, thus preventing the proper functioning of Avira. It is very dangerous to use multiple antivirus.
