This bug STILL just does not want to go away. After a full scan, there is a notification in the system tray that it is complete. But when opening the notification in the GUI, it says it is 0%. After canceling, it stops, but when you go back to check the notification, it still says 0% as if the scan is running again! WILL THIS EVER GET FIXED??
As instructed, I re-created the issue, ran the Avast Support Tool, and posted the support file for the last version in a separate thread in this forum, but this issue has not been fixed.
