Can I get a virus from communicating with someone VIA a message in FACEBOOK?
How can i scan my MACBOOK PRO for virus or spyware or malware?
Mac OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
The most effective defense against malware is your own intelligence. All known malware on the Internet that affects a fully-updated installation of Mac OS X 10.6 or later takes the form of trojans, which can only work if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
- Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown site, merely in order to use the site, is untrustworthy.
- A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim.
- “Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
- Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.

And whatever you do, pay NO ATTENTION to the zillion MacKeeper ads promising you the moon and the stars. And don't even think of installing the thing. That accursed product is worse than a virus.

There actually is Mac malware out there, but you've updated to 10.7.4 (according to your profile), so you're safe from the only malware that can install itself. As long as you don't download and run an application through a message on Facebook, or any similar place, you're fine at this time. See my Mac Malware Guide for more information.
Of course, keep in mind that malware is only one threat, and you have to keep others in mind as well, such as site redirects, phishing attempts and less technical scams. Always be suspicious of everything online.
