The one thing I noticed after upgrading to premier was that it seems to be more strict then the other paid and free prog from avast. Not that there is a problem with and I feel a bit safer but it took a minute to adjust to a prog that gave false positives on websites I have used hundreds of times with the basic paid version and know are ok.
If strict is referred to a higher detection rate, no. All avast! versions have the same detection rate.
The differences are on features and extra functions.
Glad you’ve bought and liked the Premium version.
