My friend told me I do not need antivirus software if I have a Mac. Is that true?
Macs have traditionally been less vulnerable to attack. This is partly because fewer people have it-it makes sense for criminals to go after Windows computers because there are so many of them that the virus could reach.
But that does not mean that Macs are not at risk. It’s still a good idea to get antivirus software, and Mac users, like everyone else, must be sure to download the software from sources that are known to help keep their computers safe.
