There haven't been any 'in the wild' viruses discovered on OS X 10.
So... Er... What are the virus protection programs for mac (also unix and linux) scanning for????
Microsoft files can get viruses, yup. If you send on a file that has a virus to a PC user and that PC user doesn't have virus protection then they can get the virus. Poor them. They should have had virus protection.
There was a malware / trojan (that worked via spotlight - which isn't a feature of Leopard):
> The only way you can get the Leap-A malware on your machine is if you take some action to put it there yourself. You might receive a file from a buddy in iChat, or download something from the Internet, or open an attachment to an e-mail message. The program code is presently hiding in what claims to be pictures of OS X 10.5, Apples next major OS X upgrade. To get Leap-A on your machine, you must (a) receive the file, which is compressed; (b) expand the archive; and (c) double-click what appears to be an image file to execute the code. You cannot get the malware by simply browsing the Internet, reading e-mail, or chatting with friends in iChat.
So to catch that the user needs to:
1) Receive a compressed file
2) Decompress
3) Open it
The system asks you 'are you sure you want to download this off the internet?'. The system asks you 'are you sure you want to open this program that you downloaded off the internet?'. There isn't much that you can do to protect the user from themself...
In the words of someone else:
> To date, since the release of the first Mac OS X product by Apple 9 years ago, I (a professional consultant on Mac and Unix systems for more than 10 years now) have yet to see a single virus for this platform.
> In fact, a user of Mac OS X had less of a threat of getting a virus over the last 9 years than they did of getting hit by lightning. And this isn't an idle boast, as a Mac user who was struck by lightning pointed out once.
> So here is a question for you... based on threat of lightning striking you (which currently is greater than the threat of you getting a Mac OS X virus), do you put as much time and effort into protecting yourself from lightning as you do from virus attacks on your Mac? A virus attack on your Mac may cost you your data, but being struck by lightning could cost you your life (a consequence significantly higher than data loss in my book).
> What steps are you actively taking to protect yourself from lightning? And are they more extensive than the steps you are taking to protect yourself from Mac viruses (which are currently a significantly smaller threat)?

I think that Unix systems actually are harder to crack / disrupt / infect and it isn't solely a matter of market share (macs are Unix at base). You could always run Linux on your PC...
