Now you're splitting hairs. Seriously? Talk about semantics. You and I might be able to discern - but many wouldn't discern a PC virus from any other.
Yes - it's true - a PC virus won't infect a Mac. However.
Most computers these says are called a PC. Personal Computer. Amongst laymen - many when asked if they own a PC would say "Yes - I have an iMac"
They are being "sneaking" via omission. They aren't finishing the thought - deliberately.
Macs don't get PC viruses ..... (but they can get trojans and other malware which could wreak havoc on you)
Talk about semantics and word play!
There are no OSX viruses either, so PC isn't even needed. They could safely say Mac OS X does not get viruses. They included PC so that the typical user wouldn't be mislead. To a typical user, PC=Windows and virus=all malware. So what they said is that Mac OSX doesn't get Windows malware. How is that misleading? Then in their following sentence they note that there are still some malware threats out there, but they have built in tools to
help protect you. Once again, how is that misleading?
In short, I don't see how "Mac OS X doesnt get PC viruses. And its built-in defenses help keep you safe from other malware without the hassle of constant alerts and sweeps." is misleading at all.
You also say Apple provides no education for its users; try scrolling down that page a little:
"The Mac is designed with built-in technologies that provide protection against malicious software and security threats right out of the box. However, since no system can be 100 percent immune from every threat, antivirus software may offer additional protection."
"Here are some other ways to help keep your information as safe as possible:
Download files only from known and trusted websites.
Use FileVault to encrypt your most important documents.
Control access to your Mac by locking your screen after a period of inactivity.
Securely delete outdated sensitive files with the Secure Empty Trash command."
