It's more like a problem with professional gamedev. I just find it extremely embarrassing that every time when I push an update to Steam, and a player opens up the .exe their virus scanner complains about it.
Isn't that really confusing? I know I would be asking like "What the hell, didn't I just scan this game the last time? And the time before that?"
Getting a signed certificate for the game seems to be the only way, but that seems a bit cumbersome too. Going through the process of encryption every time you make an update does not sound ideal to me. And like people mentioned in the other thread, I have built numerous Unity games as a test, and I haven't gotten this pop-up once. Like, if that has happened zero times with Unity, and it does every time with Fusion, it really makes you think.
I do get that this has been a problem with Clickteam executables before too, it's just that with newer versions of the AVG it happens way too often.
