Because of Apple’s advertising, Mac users often (wrongly) believe that they don’t need anti-virus software. The problem that these users have is that when they are hacked, they have no way of ever finding out. The intruder can be watching them while they type (by way of viewing the user’s screen or even watching them through the webcam) and listening on their microphones. Once I explain this to Mac users, the next thing they ask me is ifÂ there are free anti-virus programs for Mac. Here is a list of the three I’m aware of; if you know of more, please let me know.
Just having one of these anti-virus programs installed, or even just regularly downloading the latest virus definitions is not enough; it’s the regular full system scans that do the detection.
