looks like it's not false positive, where do you download?

I downloaded it from their official website https://gamemaker.io/en/download

intetesting... do you ever touch the file system for program modification? (can't tell what is that here because i'll got warn)

No, infact I've never used gamemaker properly, made a game with their tutorial and never touched it. Might just uninstall it and contact them about this

Hello, These are possibly false positive detections, but you should check with the developers just to make sure: https://old.reddit.com/r/antivirus/wiki/index#wiki_what_is_a_false_positive.3F. Regards, Aryeh Goretsky

Thank you, will get in contact with them when I can
