I think it's a false positive. Over the years, grabbing random roguelikes from around the internet, I often get them. Apparently lesser known files can trigger some virus detectors just by virtue of being lesser known. Let me know if anything else pops up, and I'll see if anyone else chimes in with the issue. But I just ran about 60 different tests to see if I could determine anything amiss, and it's checking out as fine no matter what angle I take. Thanks again for bringing this to my attention!
