You’re welcome.
For me the Smart Scan has only ever pointed areas that I could be better protected, e.g. other Avast Paid products.
Well the wording ‘Limited’ is the key it basically keeps them down to a dull roar, I don’t think this will ever get down to ‘Disable’ - that said With avast Free and the settings I mention it is an infrequent notification, certainly on my system.
