9 Consider a Virus Scanner
Macs are not as prone to computer viruses as Windows PCs, for a variety of reasons. But that doesn’t mean that Mac malware isn’t out there. Whether or not a macOS virus scanner is essential is still undecided among Mac owners — but we still think it can help.
An option like Malwarebytes is a good and free choice. It doesn’t even need to be on consistently (which can slow down your Mac). Just try to start up the app and scan your computer every now and then to make sure that it’s free from adware, malware and other unwanted malicious programs.
