Only Visit Trusted Websites
Not only should you stop downloading apps from untrusted websites, but you should stop visiting them altogether. Some websites use malicious software or fake ads to make you install apps you weren’t even looking for in the first place. Some websites go as far as showing you a pop-up message telling you that your Mac is running slow or that it might be infected, only to make you click on a button or download an app that may end up infecting your Mac. It’s best to avoid websites with scary pop-up ads or ones that ask for strange information. Avoid interacting with these sites or leaving them open for too long on Safari or your browser of choice. It’s best that you only use websites you know and trust to avoid any problems.
