Hello Peter, Darren,
Thank you for your followup on this and for contributing to our forums.
As Darren also mentioned, this is a false positive:
False Positive Virus Detection
Unfortunately, the only thing left to do here is to submit the setup for whitelisting to Microsoft.
This is something we do every month before each release as well - we actually had some detections from Microsoft Defender and we have submitted the files for false positive and everything turned out to be ok afterwards.
Now, a few days later, it looks like the setups are detected, which is quite strange.
Could you please also submit the file for whitelisting and let me know how that goes?
