QB64 Phoenix Edition v3.9.0 Released!

[a740g]

The message is: "Trellix Endpoint Security Alert. The file cpp.exe was detected as a threat and deleted."
. . .
From what you guys say, though, the issue did not surface because of version 3.9, but rather, because something in the McAfee settings was changed. That being the case, I can't complain to QB64pe.

Then only the person who set it up can help you, the administrator. Explain the problem to him.

They will probably ask for a "business case / justification".  

Our company moved away from McAfee this year to the MS built-in security. Everything has been good since then. Good riddance!
