I have the warning as well. Flagged as Wacatac, so very likely a false positive again. I recommend you DO NOT use anything that is flagged, ever, including Monkey.
For context I've lost MANY weeks of debugging this issue for Monkey. This included creating a new machine from scratch, comparing byte codes patterns, and testing in multiple regions.
Microsoft defender will detect some byte stream patterns and flag them as virus. Those patterns are machine learned locally and rules will apply differently based on rule sets, region, and product tiers (i.e. business tiers).
The only solutions I found is to change/recompress the data until you get a byte stream that works, OR pay Microsoft & partners for a code certificate to sign the data. Depending on how much you pay and which agency you use, your bytes will quietly pass through.
While virus is a complex problem to solve, I can't help but believe this is a nice lucrative Byte mafia.
If you are comfortable with risks, you can run any file through an online scanner like virus total. It will usually confirm the safety of a file flagged by Microsoft.
