Besides making sure not to download the wrong programs that can be fake programs like fake wallets and not clicking on links, what other important things should you do to protect your computer? Yes i know you should not put crypto in it but even those who have hardware wallets, some coins cannot be put in the hardware wallet and you need to put it on its own wallet you install or in an exchange.
I always have at least one antivirus and antimalware to protect my computer. Also save all important files and data in your flashdisk, so if your pc got hacked or something bad, your information still save. Stored all your coins in hardwallet is a good choice too, more safety than web wallet or online wallet.
