Hello, im using itch io for some time now and this is the first time this happened to me, so yeah.

After downloading the game, i extracted it and windows defender went crazy saying it contains a trojan

This is the game in question: https://black-cat-entertainment.itch.io/guardiansofeden

Trojan: Trojan:Script/Wacatac.B!ml

I regularly see games with malware. Though I do not download them to check which malware is in it.

I made a thread about it.

That being said, there are cases where there are false positives. But better be safe than sorry. Against some malware it helps to use sandboxing.

Even legit developers could get hacked and unknowingly upload malicous apps.

(This was of course malware.)
