If you see a message from your anti-virus software saying anything like "a threat has been detected" — there's no need to worry about your computer's safety after downloading the game, we're completely safe!
Because we're a young company, some anti-virus programs block things they don't recognize or that self-update like our game does.
Setting up your anti-virus software to let you download/open/play the game without any problems is called "whitelisting" or making an "exception." Below are some links to help you whitelist our game files depending on which software you use.
