There are now over 32,000,000 Macs in use around the world. When will we reach the magic number that will result in ONE viable self-replicating, self-transmitting computer virus that infects OS X Macs? When will Macs attract the attention of your hackers???
Keep in mind that the Witty Worm was written to infect vulnerable computers using Black Ice firewalls six months AFTER a patch was distributed to fix the vulnerability. The total number of potential vulnerable computers was just around 10,000. Every single one of them was infected 45 minutes after the Witty Worm was released into the wild. Why hasn't anyone written a Witty Worm for OS X Macs? Could it be that the architecture of the OS is far more secure than is Windows?
Bingo.
I have worked on/owned Macs for nearly twenty years. I have never once had an issue with viruses, spyware, Trojan Horses, etc.
I also have had three Windows-based laptops for my other job. They are constantly alerting me to all of the above. I also have a semi-annual scrubbing done by our tech guys; they always find THs and viruses that my top-o-the-line security software does not.
I’m not a software engineer, but I know what works.
