As Kuraizu suggested, i have used the Repair App shown on the image.
No comments made, just went to the Smart Scan panel.
See how it goes and thank you.

Whilst a Repair could well fix an issue, I don't believe it would fix what you are reporting. This was considered a bug previously which should have been fixed. However, there may still be times when a restart is required to implement an update/micro update/fix.
As far as a Repair goes I always say to do a reboot after it (whilst that may not be mentioned in instructions), that could well fix many other computer glitches, etc. much less the need for a restart to implement an avast fix/update.
