Malware warning when installing mandatory update after sim reinstall

[Stinknado]

I got this same warning. I installed MSFS over night and woke up to two malware threat warnings:

1. Backdoor:Win32/Bladabindi!ml
2. Trojan:Script/Wacatac.H!ml

Both from this file:
D:\FlightSimulator\Official\Steam\microsoft-airport-kffa-firstflight-0.9.7.fspackage.part

My pc is a brand newly build pc only a couple of weeks old with a handful of games installed from Epic and Steam and handful of purchased apps I can count on ten fingers. The only thing that makes sense is this is a false positive. But NOT a great first impression of MSFS.
