Since this is a ‘detection’ this is I believe not the regular “Show detailed info on performed action” so it has no effect, if it were enabled you would see ‘all’ the clean files that the standard shield is scanning as well.
You should also have had the avast Alert pop-up and an audible alert.
First you get this Blue and Yellow notification followed by the alerts.
I did a test on one of my samples and standard shield (I to have the default setting of no “Show detailed info on performed action” notifications) first displayed the notification, followed shortly by the pop-up and audible alert, so it would appear that avast is working as expected.
