Awh, thank you so much!
It's not a trojan virus, it's just that i develop with an ancient version of Gamemaker. It's a false positive! It probably happened too with a previous version.
It's a false positive with "executable builds" (so, like, when you download the game and it's just an .exe instead of a folder with a bunch of files, i prefer this option as it's a small game and less hassle for people who download it)
If in doubt though, i respect if you don't download it! The htm5 version is the same, so you can play here! (:
