    Check the first section in
    Mac Virus/Malware Info by GGJstudios
    There are currently no viruses for Mac OS X in public circulation, only a handful of trojans and other malware, which have to be installed manually via entering the administrator password.
    The only anti-virus you need to protect your Mac is education and common sense.

    And Mac OS X does not have drive letters (H drive).

    The assumptions in that article are bogus. As it has been for the past 10 years, the only malware threat to Mac OS X that exists is an ignorant or careless user, since the handful of threats that exist all require the user to actively install them.

    There has never been a virus in the wild that affects Mac OS X since it was released 10 years ago. The handful of trojans that exist can be easily avoided with some education and common sense and care in what software you install:
    The first section of that link deals specifically with the MacDefender/MacSecurity/MacProtector issue. I encourage you to read it.

    Mac OS X will not have the same malware problems as Windows. The main reason Windows has so many issues is the Windows OS with the greatest market share, XP, does not use discretionary access controls (DAC) in the account type, admin, used by most users. An OS has no user space security mechanisms and many trojans can install without authentication when run without DAC. The primary user space security mechanism in this regard protects security sensitive data from being logged when entered into password prompts and web forms.

    Also, even Windows 7 has a higher liability to have more malware issues due to having a greater number of privilege escalation vulnerabilities.
    Privilege escalation is required to install rootkits that bypass user space security mechanisms in OSs that use DAC unless social engineering ploys trick unknowledgeable users.

    Most OSs provide enough security such that malware that relies on social engineering, such as MACDefender, is obvious and easy to avoid with a little bit of user knowledge. Even if the volume of Mac OS X malware increases proportionally in terms of market share, the incidence rate of successful infection per capita will not equal that of Windows, specifically XP, due to using DAC by default and having fewer privilege escalation vulnerabilities.

    Other examples show that the more targeted platform is that which is easier to exploit. Microsoft IIS is exploited more than Apache despite Apache having greater market share. Android OS has more malware than iOS despite roughly equal market share. The large volume of Windows malware is due to both being an easier target and greater market share.

    I remember seeing a thread like this with a screenshot.

    I encountered the infamous "Your Mac has a xx viruses!"

    Hehe, it's fake.
