As long as you download it from the right spot, then you should be good to go. Under the "download" tab, click "web setup", "download", or "torrent" right next to where is says "FeralHeart Game Setup" (or click "download" next to "FeralHeart for Mac" if you own a Mac). Don't click the other random "download" options nearby, those are the downloads that aren't FH-related and that probably lead to a virus
