It’s more essential to update anti-virus utilities than most software. However, some users have stated on forums that their AVG anti-virus utilities don’t update.

That leaves them with outdated AVG anti-virus software. Here are a few resolutions that might fix an AVG utility that isn’t updating.

What can I do if AVG fails to update?

  1. Manually Update AVG
  2. Change your antivirus solution
  3. Delete Temporary Update Files
  4. Scan for Malware
  5. Turn Off the Windows Firewall
  6. Reinstall AVG Antivirus

1. Manually Update AVG

First, try updating AVG manually. That’s not exactly a fix for AVG‘s automatic updates, but at least you might then get the software updated. This is how you can manually update AVG.

  • First, open this page in your browser.
  • Select your AVG version on the page, and then click update to save to HDD or USB drive.

  • If you’re utilizing the freeware AVG, you can get the July 2018 updates from this webpage.
  • Open your AVG utility in Windows.
  • Click Options at the top right of the AVG window.
  • Then select Update from directory to open a Browse for Folder window.
  • Select the folder that includes the AVG update, and press the OK button.

2. Change your antivirus solution

If AVG does not make the cut, it might be a good idea to consider replacing your antivirus with a more well-balanced security solution that benefits from regular updates.

3. Delete Temporary Update Files

Deleting the software’s temporary update files might fix AVG updates if AVG returns an update or general error message when updating. To do that, open the AVG window.

  • Click Options and select Advanced Settings on the menu.
  • Click the + to expand Update, and press the Manage button.
  • Then you can select a Delete temporary update files option.
  • Click Yes to confirm and erase temporary update files.

4. Scan for Malware

Malware can block AVG updates. As such, purging malware might fix the utility’s updates. You can do that with Malwarebytes.

Press the Free Download button on this page to add the freeware Malwarebytes to Windows. Then you can run a scan with that software by pressing its Scan Now button.

5. Turn Off the Windows Firewall

The Windows Firewall might be blocking AVG from updating. To ensure that isn’t the case, you can temporarily switch that firewall off. This is how you can turn the firewall off in Windows 10.

  • Open the Cortana search box by pressing the Type here to search button on the taskbar.
  • Input the keyword ‘Windows Defender’ in Cortana’s search box, and select to open Windows Defender Firewall.
