Hello, Bert.
I apologize for the inconvenience caused. I'd request you to remove the existing schedule scan and add a new schedule as per the instructions provided in this article http://support.avg.com/SupportArticleView?urlname=How-to-start-or-plan-a-computer-scan.
The update to version 18.4.3056 dated 5/10/18 has apparently broken the software that runs a scheduled scan. The user interface still lists that a schedule scan has been created, but the scan does not occur.
