Thank you @Berny for the suggestion. But who can be sure that MSF executable doesn’t contain that worm? So I would like to get this issue fixed in Kaspersky product or inform us that KAV is a hero and prevented infection.
Same here. Nor Virustotal nor Kaspersky itself are not finding anything suspicious in FlightSimulator.exe, but KAV is breaking MSF2020 run and removing FlightSimulator.exe.
