. PLEASE. name a successful real computer virus, that is not a Trojan Application, that was EVER in the wild for Mac OSX. I DO know quite a bit about computers. . . especially Macs. Keep in mind the actual definition of computer viruses. Also, keep in mind that I am completely familiar with EVERY OSX "virus" candidate that has been suggested or put forward in the past fifteen years since OSX Server was introduced and why all failed to make the grade as a successful virus that could infect a Mac.
It took over nine years for a successful Trojan to be written. And it was an easily avoided Trojan at that, as are all of them for Mac OSX, as is this one.
You will notice the way I framed it: It CAN be done. There is no completely secure system out there.
Mac OSX is in no way completely immune, and that is 100% true. And I say this both as a person who has never personally owned a PC in the computer age (I have only owned Macs) but also as an IT professional.
This is because, in practical terms, the risk is small enough that for me, as an IT professional (and many I know) I do not use antivirus software on Macs. When one makes it “into the wild” and causes actual I will reconsider my stance on antivirus software.
The rule of thumb is that if you can conceive something happening, there is a likelihood that it WILL happen someday. My way to be safe it is making sure I have staggered backups in duplicate.
