Comment 23 for bug 1665768

Thanks for the report! I'm pretty sure this is a false positive (see scan results by Virustotal [1,2]). Gen:Variant.Graftor.* is "A Generic Detection of a file that appears to have trojan-like features or behavior." [3], i.e. an heuristic match.

That being said feel free to send those files to you virus scanners creator for detailed investigation to rule out any doubt (likely they'll just update their heuristics).

Also note, that those files were never on *my* machine. They are CI builds by AppVeyor, so if a virus were to be contained it comes from either one of the MSYS2 binaries or one of their virtual machines (both not completely impossible, but unlikely)
