Fix AVG Anti-Virus Update failed – The update control file is missing

We had a customer’s Windows 7 computer running AVG 2015 Anti-virus, managed by AVG Cloudcare, that was refusing to update its virus definitions database.

Update failed.

The update control file is missing.

Note: This error has been reported on non-Cloudcare versions and earlier versions too.

Even getting tough and uninstalling the software with the AVG Removal Tool, rebooting and reinstalling .. left me with exactly the same problem. Other computers at the site were unaffected.

Kudos to Bryson from AVG Support who suggested this process. It worked perfectly, first time!

  1. Disable AVG Self Protection (options > advanced settings > AVG Self Protection)
  2. Delete the file C:\ProgramData\AVG2015\cfg\update.cfg
  3. Restart the PC and enable AVG Self Protection. The cfg file is automatically recreated with default settings.
  4. Update

 

Leaving here for posterity, in the hope it helps someone else who’s turned to searching Google!

  1. Thanks for this – had exactly the same issue on a brand new, totally clean Cloudcare install today. My patience really is running out with AVG. Had so many problems with their products recently.

    Cheers

  2. Didn’t work EXACTLY as explained but it did work!!! Had been chasing my tail for three days trying to get a virus update. Many thanks.

  3. This worked great for me, too. Being an old DOS guy, I opted to use a COMMAND prompt and RENAME UPDATE.CFG to UPDATE.SAV just in case. In order to do that, I had to right-click the Command Prompt icon and RUN AS ADMINISTRATOR. Thanks for the solution!!
