Some people might think Macintosh computers are only susceptible to security issues over out-of-the-common things like the deleterious Meltdown and Spectre microprocessor flaws, but that’s a big misconception.Ī slew of garden-variety PUAs (potentially unwanted apps), adware, browser redirect viruses, rogue system utilities, ransomware, and cryptojackers are out there targeting Mac machines on a massive scale. Macs aren’t in the risky red area in this context, but nevertheless, malware outbreaks are constantly occurring in this ecosystem. There is no operating system immune to viruses, and a magic vaccine to fend them all off has yet to be invented. Find out how to tell if your Mac has a virus, what to do in case of infection, and how to prevent different forms of malware from contaminating a Mac.
