I have exactly the same issue here with Microsoft Flight Simulator, after updated to V1.15.7.0, my Kaspersky Internet Security detects the Flightsimulator.EXE as PDM:Exploit.Win32.Generic.nblk The update came directly via Microsoft Store on Windows 10 Pro 20H2. So, seeing what happened back in September 2020, this is pretty sure , again, a false positive, please solve it quickly, I was developing scenery for MSFS and now I’m stuck here…... I currently have KISv21.2.16.590(c) with 2021/04/13 database.
