Yes, I'm using another engine, clickteam fusion 2.5, I'll try that, but early on the project I gave a build to my friends without a custom icon and their PCs detected it as a virus. As every other project on that engine. I tried to fill every information boxes, and didn't worked. I asked them if scanning the file with windows defender tells that is a threat and it didn't. I think it can be some object in the game, because in the engine you can add objects posted by the community, I used one for platformer physics, maybe it's that. Anyway, thanks for playing and for your help :)
Ahh I see. This is indeed a strange problem. Though I don't think the object you said you added in the game could be the cause, as the same thing many people do in Unity as well. I dunno but this sure is a hella weird problem lol. I too faced it with my first game, though changing icon back to default worked for me.
But anyways, the game was really good, keep up the great work. And happy game developing!
