This is defiantly disheartening to read ,I downloaded couple of games off here and while they are safe(because I have semi follow the creator's work),it's definitely putting me on edge to download games anymore especially off here.It doesnt seem worth if every game has high possibility of being a virus.
The best method I have come up with when first coming across a game is to check creator's previous work or see if the game has videos on it.If it does and I like what I see.I will download it and put it through couple of antivirus scans
