and they said macs dont get viruses
They can. They have in the past, before Mac OS X. They don't since Mac OS X, only because none have been released into the wild.

Yes, they do. They get trojans, but not viruses.
I just love how sheep continue to spin this by saying, "It's not a virus, it's a trojan.",
And by "sheep", you mean "informed users who know the difference", of course!
Virus, Malware, Trojan, or whatever, the everyday user doesn't care about the technical definitions.
The difference determines the proper defense. I love the approach that "the masses are ignorant of the differences, so rather than try to learn and inform others of the facts, let's just join the masses in their ignorance!"
As much of a machead as I am... even *I* can't gloss over the fact Apple dropped the ball on this.
They absolutely did. It's far from being the only time. They dropped the ball by shipping Macs with the default settings of having the firewall disabled and Java enabled (for the versions that shipped with Java installed), and "Open "safe" files after downloading" enabled in Safari, to name a few. The good news is that a user can pick up the ball by correcting such things. I don't leave the security of my computers in the hands of a hardware or software company. I take responsibility to make sure my own computers are secure. Did Apple drop the ball? Absolutely! Did it affect my computers that they did? Not at all.
When it's on Windows it's a virus. When it's on Mac that's when you have to be specific
There's a reason for the distinction between the two platforms. If all malware could be easily avoided by practicing safe computing, and all users practiced safe computing, there would be no need for antivirus software. However, a virus changes things. Once a virus is released in the wild for a platform, practicing safe computing is no longer sufficient to provide a complete defense. At that point, antivirus software is required. Once you have a dependency on antivirus apps, they can be used against both viruses and other forms of malware.
No OS is immune to malware, especially the greatest threat to security: the user. With Windows, the "virus cat" has already been let out of the bag, so running antivirus has become common for Windows users. If and when a virus is released in the wild for Mac OS X or later, the same will be true for Mac users. We're just not there yet, since safe computing practices can still completely protect against all Mac OS X malware in the wild.
Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided by practicing safe computing (see below). Also, Mac OS X Snow Leopard and Lion have
anti-malware protection built in, further reducing the need for 3rd party antivirus apps.
- Make sure your built-in Mac firewall is enabled in System Preferences > Security > Firewall
- Uncheck "Open "safe" files after downloading" in Safari > Preferences > General
- Uncheck "Enable Java" in Safari > Preferences > Security. This will completely protect you from the Flashback malware. Leave this unchecked until you visit a trusted site that requires Java, then re-enable only for your visit to that site. (This is not to be confused with JavaScript, which you should leave enabled.)
- Change your DNS servers to OpenDNS servers by reading this.
- Be careful to only install software from trusted, reputable sites. Never install pirated software. If you're not sure about an app, ask in this forum before installing.
- Never let someone else have access to install anything on your Mac.
- Don't open files that you receive from unknown or untrusted sources.
- Make sure all network, email, financial and other important passwords are complex, including upper and lower case letters, numbers and special characters.
- Always keep your Mac and application software updated. Use Software Update for your Mac software. For other software, it's safer to get updates from the developer's site or from the menu item "Check for updates", rather than installing from any notification window that pops up while you're surfing the web.
That's all you need to do to keep your Mac completely free of any virus, trojan, spyware, keylogger, or other malware. You don't need any 3rd party software to keep your Mac secure.
