There are the possibility that they are false positives, but "The anvil section" is marked by windows defender like a trojan, and "un petit noel" have 3 alerts in virustotal, looks like a game made with game maker, so maybe be a pirated version, that is a only a theory, nothing confirmed because i not put these games in some of the services to test malware. I had not execute any of the two executable. The game that i mentioned its "un petit noel", but like i says before, maybe they are false positives, the better way to see if they are malware its using services that can check what they do in the machine. Its really frustrating that there too many risk to play games now.
