Oh, I get it. If you want, you could try downloading the game through the Itch App, and running it in the sandbox, there's a chance it might help.
It's not a problem. :) I looked into it and I think I found out what causes the false positive. I have a custom icon made, and apparently it freaks out some of the antivirus programs, especially Avira. You could try some of the free online scanners like ESET for example, if you want to be extra safe.
