Can someone tell me why there are thousands of viruses for Windows PCs and none for Macs?

Why are Macs immune to viruses?vincent

Here's a link to a good article on this very subject. It explains exactly why Macs are less vulnerable to attacks than Windows systems. It's quite technical, but it's all true. Don't let people tell you it's due to lack of users and low market share, it's just not true. It's all about Mac OS X's UNIX underpinnings. Here's the link below.

There are so many misinformed people. I don't know who started this rumor, but it's just not true. There are many safeguards in OS X that Windows does just not have. Take it from a real Mac user who has yet to any viruses or spyware. Most PC users have no idea why they get the viruses and spyware they get. They just think it's because they didn't have their anti-virus or anti-spyware programs up to date or something silly like that... It's the simple fact that Windows is a shoddy operating system. I know, because I used it for over ten years before switching to Mac. I've used every Windows version under the sun.

They aren't. There are just less viruses written to attack Macs because less people have them.
Virus creators want to infect (spread) their evil to as many computers as they can. Since there are many more pc's than there are Macs, they focus their evil on pc's. Just like Internet Explorer is more likely to get a virus than a person that uses Firefox, Flock, Opera or a less popular browser.
You are wrong. There are fewer virus writers for the Mac. Most virus writers use the PC because there are probably more security holes in Windows, and it is more likely to infect a lot of machines. There are less Macs, so it is not worth the effort to write a virus for a Mac.
