If Macintosh ruled, all the viruses would be written for the Mac instead...

Why aren't any viruses being written for the Mac now?

Maybe because Macs aren't vulnerable to viruses?

Any computer that can exchange data is venerable to viruses.

Most successful viruses running around today like MyDoom were executable attachments that people opened. Any machine that will execute the executable is venerable. It didn’t matter if all the ports were closed, firewalls were in place or anything else to do with the operating system. If the user chooses to run the attachment the machine has been compromised right then and there. MyDoom didn’t use active X, it didn’t use VB scripting, it used native code to the computer and a venerable user. Venerable users aren’t unique to PCs.

Make that "vulnerable"...

[HairOfTheDog]

Anything that is popular is vulnerable.

Virus writers get more bang for their time disrupting big numbers of WIN users than they would annoying relatively few mac users. It is return on investment.
