you need to download the game from a legit source
I don't believe the dev would actually publish to pirate sites a malware infected version of the game as that is VERY ILLEGAL and would have repercussions far worse than personal pirating. There is however apparently 2 fake-out versions going around, though. Balloon heads and a spoopy fake you've been had screen with broken Cyrillic that's supposed to be Russian or something. As well as English saying all your important stuffs has been stolen, encrypted and uploaded with no internet connection all within 20 seconds (wow, impressive work. I think the CIA might want to hire this guy whoever he/she is.) The dev is very likely swapping out links after the auto scraper site/s do their thing with fake-out links to deter piracy but admitting to that would be bad news and a scandal waiting to happen. My advice to the dev is just ditch the fake-out screen and either replace it with a black screen or stick to inflated heads. There's already people whining about malware and accusing you to boot. Can't see this going anywhere good.
