Would you recommend purchasing anti- virus software for Mac?

I just bought an iMac this past week and was wondering if I should buy the 9.99 Kaspersky antivirus software? I know that Mac offers updates that keep their computers safer then PC's but still need to know if it is good to have the extra security from the software.

You don't need any 3rd party antivirus software to protect Mac OS X from malware. 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 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 with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.
There have been many reports of antivirus apps creating performance problems with Lion. They are not recommended.

Not sure how you're connecting to internet, but I'd make sure you have good firewall protection with your router as well as make sure your OSX firewall is on too...

See System Preferences > Personal section > Security > Firewall tab...

If you want extra protection and don't need file sharing, etc, you can click the 'Advanced' button and select 'Block all incoming connections'...

Yeah you don't need anti-virus on your Mac really. Especially with Apple's security updates and firewall, you're probably safer without an antivirus than a Windows computer with one ;)

I just have Clam AV on my Mac for those in-case situations when I need to send or receive files from a PC, but I rarely use it if at all. It's free so I figured why not. I'm not sure if it even offers real time protection but I don't have it turned on anyway.
