As has been mentioned by Vlk I believe the memory scan is a throwback to the dark old days of AVs and as has been said the option is to prevent it getting into memory as essentially it is to late.
The main problem here is seeing something that cause the end user concern as they think their system is infected. When in this case it isn’t.
If you do set it then it does require a reasonable knowledge of avast and the users system if something is detected in memory. Of all of the occasions when these detections in memory have been reported in the forums it has been as a result of other security software loading signatures into memory and doing an in depth memory scan.
For the majority it scares the pants of them as they can’t select any actions and or the Apply button is inactive. So I wouldn’t say it doesn’t hurt as we have no idea how the user might react to the alert.
