Honestly, it is hard to stay away from hackers nowadays because they can easily steal all of your funds in your wallet easily, that is why you should avoid sharing your private keys to anyone and avoid putting it in an unsecured place like inside your desktop or an online storage which a hacker could easily access to it. You should be keeping your private keys in a secured place like in a flashdrive which no one could access it so easily or writing it down on a paper.
