THAT HAPPENED TO ME TOO! But my antivirus said it was a different threat. I don't remember much, but when I searched it up Google said it was most likely a false positive.
I don't think the game has a virus/malware in it, but I'm unable to play the game now. Even when I try to unzip the folder again, it says "Destination folder access denied" at the last moment.
So far, I haven't found a solution for it :(
(I only played a bit of the game, but it's really good! I hope you're able to play it soon!!)
