Guys, I understand your comments but using McAfee is my employer's decision so I cannot workaround it, so be patient...
I have investigated this issue in details and I have identified the cause. McAfee Antivirus/Malware detects B4A executable (3.82) as a "potentially infected" file, even if it does not associate it with known virus or threat definitions.
According to McAfee the fact that it keeps being detected means that it has already been detected on other systems, so it makes sense to fix this for anyone facing the issue and for any future B4A customer.
Here is the procedure that the owner of a detected software should follow in case their files are being quarantined as false positive:

And this is the DetectionName as found on my computer (required by McAfee to submit the claim): Artemis!10BAC82FC3BB
I would be very glad if someone from B4A support could apply for the procedure at:

to solve this issue completely.
Thanks
