Security expert Charlie Miller stated in an new interview that despite the appearance of the new "MAC Defender" trojan malware title, most Mac users don't need to install antivirus software.



From Apple Insider:

The "MAC Defender" threat is a website that fraudulently indicates to users that real viruses have been detected on their computers, and recommends that they install "MAC Defender" antivirus, which is actually a malicious bit of software designed to harass users into paying for phony antivirus services.

The malware is not a virus, as it can not install itself or spread on its own. Instead, it relies upon fooling non-technical users into installing the malware through Mac OS X's security authentication barrier, and additionally attempts to get users to supply their credit card information.
