And I've now looked back at my download page, and found this paragraph,
which might have saved you the trouble of posting a warning about false
positives:
"If you are a magical-thinker who uses anti-virus software on your Mac,
your software may alert you with false positives. It is entirely up to
you what to do about those warnings."
This is the fourth paragraph on the page, so it should not have been
hard to find:
