Thank you, for your answer. Only to be sure, the Threat Scan did take 13:29 minutes and 330,658 objects scanned. The heuristic analysis at the end did need only 4 to 5 seconds this time.
Is that not to quick? I remember in the past, this take longer. I have also a friend, when he run a Threat Scan, his heuristic analysis take at the end around 60 seconds, every time, with around 400,000 objects scanned.
We both use MBAM 3.5.1.2522 and I use Windows 10 Pro 1803 up to date.
Thank you for the hint about to disable the Premium Trial, this is very useful .
Thanks
