Really...? You're going to flag an itch.io registered dev as a hacker...? When absolutely none of the scanners trip on his stuff on virustotal...? When 7zip doesn't even DO virus detection...? And using AI having to do NOTHING with writing malicious code...? What exactly are you playing at here, dude...?
game got an update since his post, most likely initial release was marked as a virus by certain antiviruses/browsers/windows smartscreen/defender , and by "7zip" he most likely meant smartscreen
anyways generic false positive nothing new,
for other users - generally virus or a false positive can be identified by virustotal or having malwarebytes/eset(nod32)/kaspersky on your system, generally it's possible to see false positives by analyzing virustotal results, so something like 20/50 detections on virustotal can be good actually if at least some antiviruses saying stuff such as "hacktool/crack/keygen" , then you know that it's most likely safe even if e.g. 10 of these 20 saying that it's a trojan
