Smart Scan not running

Hello Owen.
We're here to help.
We'd request you to repair AVG to resolve this issue.

Owen, we appreciate your efforts but regret to hear that the issue persists.
Please make sure you do not have any 3rd party antivirus installed on your PC.
Then, uninstall and install AVG AntiVirus free again to resolve the issue.
I had no other Antivirus software installed on my PC but I uninstalled AVG and reinstalled it anyway and it made no difference. The same problem occurs.

Whenever I press the Smart Scan option on my AVG antivirus, the avg screen just goes to a blank background. The bar at the top shows the AVG Antivirus Free logo and the notifications and meu options still show but it doesn't scan.

Sorry for the inconvenience caused.
As a last part of the basic troubleshooting steps, please run AVG Clear tool to remove and install AVG AntiVirus free again and verify the issue.
