Avira Antivir - Error loading system components

Ask a question

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.

Windows Defender

According to Avira, Windows Defender is now inconsistent with Avira (for Vista users and Seven). Nevertheless, this program isn't responsible for this error. You are free to disable it or not, it's up to you
