The first and best line of defense is always your own intelligence.

See If you want an antivirus, you can use Sophos or ClamXav, but you only need them if you have files you will transfer to Windows PCs.

OS X includes a number of security measures to combat malware (Gatekeeper, XProtect, and a built-in Firewall); however, no system is completely foolproof.

One of the best ways to protect your system is to develop computing street smarts and know how to identify and avoid suspicious locations and files on the Web; however, this takes time to develop.

If you are uncertain of what to look for, and would feel more comfortable having a tool help you scan for and identify malware, then Id recommend installing a lightweight and free malware scanner like Sophos Home Edition ( ition.aspx ).

Of course any additional software you add to your system may adversely affect it, so often anti-malware tools are seen as unnecessary because of the potential for being intrusive without much benefit in return, given the relatively low level of malware that targets OS X.

However, despite claims here and elsewhere of problems with their software installations, most anti-malware tools work just fine for those who have installed them, and reside benignly in the background, scanning and doing their thing.

They will help detect known threats if you encounter them but are not guarantees of full protection.

Therefore, do not assume that with one installed you will be able to freely open any file you find and be safe.

Still apply caution to your actions online and elsewhere, and be wary of offers, unknown files, popup windows, and random update warnings (especially through email or Web pages).

In reality of course, there is no such thing as total internet privacy: US and British intelligence agencies have successfully cracked much of the online encryption relied upon by hundreds of millions of people to protect the privacy of their personal data, online transactions and emails.

It does not apply to software, such as keystroke loggers, that may be installed.

That threat is in a different category, and theres no easy way to defend against it.

If you have reason to suspect that youre the target of such an attack, you need expert help.

This feature is transparent to the user, but internally Apple calls it XProtect.

The malware recognition database is automatically checked for updates once a day; however, you shouldnt rely on it, because the attackers are always at least a day ahead of the defenders.

Software certified in this way hasnt necessarily been tested by Apple, but you can be reasonably sure that it hasnt been modified by anyone other than the developer.

His identity is known to Apple, so he could be held legally responsible if he distributed malware.

That may not mean much if the developer lives in a country with a weak legal system (see below.).

It has, however, the same limitations as XProtect, and in addition the following.

Sandboxed applications may prompt for access to private data, such as your contacts, or for access to the network.

Never click through any request for authorization without thinking.

MRT runs automatically in the background when you update the OS.

It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks.

It notifies you if it finds malware, but otherwise theres no user interface to MRT.
