That bit of Mac-Head mythology will get you in trouble. More proof Mac's are more of a religion than a computer platform
Please read the rest of the thread. Renepo is a piece of Malware that requires a user to manually install it, and give it administrator privaleges. It isn't a virus. It can't transmit itself, and unlike the windows scripts, it can't be run simply by opening a file attachment.
Look, I never said Macs were 100% secure, they aren't. There are numerous known exploits and I just installed the latest security patch this morning.
However, when it comes to viruses, there are absolutely no known viruses that effect OS X. All the examples out there that folks are throwing at me require manual user action to install them, including giving the script administrator privleges. You can't screw up a Mac by simply opening an e-mail attachment. And there is nothing out there that will mail itself to your address book.
