Historically, Windows users were always the ones getting blitzed by malware. Viruses, worms, you name it, Windows PCs got it. Lately, though, malware is appearing that targets Macs as well.
I know some Mac users refuse to believe it. Believe it. Even Apple finally admitted that Mac Defender Malware was a real and present danger.
Don’t get too bent out of shape about it though. Just because Mac malware exists doesn’t mean that your Mac is as unsafe as an unpatched Windows XP PC. It’s not. It never will be. Windows, by its very nature, has always been more insecure than Linux or Mac OS.
From the day of its creation, Windows was designed to be a single-user system in an non-networked world. That hasn’t been true for more than twenty years now. Linux and Mac OS roots though go back to Unix. Unix was designed from the ground-up for a world with multiple-users and networking.
But that’s no reason to lean back with a big stupid grin on your face and think that you’re safe as houses. You’re not.
