    Once upon a time, the score was Mac 32, PC 70,000 when it came to viruses. Now that Mac OSX is around, pretty much the only viruses you can catch are from old copies of MS Office, or yeah, from illegal software trojans. Even if you get a virused email for a PC, it can't propagate on your machine.

    The answer is "Yes and No"

    Yes = ClamXav ( ) That will scan your drive for various known viruses, is fully free and uses a free virus database that is updated regularly (don't know exactly what the response time to new threats is, though). Oh, and it only runs when you tell it to (I believe you can schedule it to run at a certain time) but it doesn't do the continuous checking that sucks down resources like Windows AV solutions do.

    No = There aren't really any viruses for OS X. Just be careful of anything you download that requests/requires your admin password to install (ie: stop and read those popup windows). It is ok to trust published software you're installing from a disc, from a known company - at least there'll be culpability if their software installs a trojan.

    So, why ClamXav? So you know you're not cross-infecting Windows machines of friends, family, or coworkers (anyone you might email or share files with).

      I used ClamXav until my company offered something else for free to all employees even for home use. In my experience ClamXav has a lot of false positive errors and even missed some really bad stuff for Windows.

      ClamXav runs Windows and OS X virus scans. I must use both Windows and OS X due to my job.

    As far as I can tell, among the rare viruses that are a problem for Mac users occur when they share Microsoft Excel and Word docs with Windows users. There's an ancient virus that lives in MS macros. Mac users are unaffected, but the sirens blow when a Windows user opens a doc received from the Mac user. The worst fallout is that the Mac user looks unprofessional to the Microsoft PC user.

    If you can live with that, you're probably ok with ClamXav ... which detects bugs, but doesn't fix them .... and it's free.

      That is probably why Office 2004 and 2008 Mac can't run Visual Basic in Word or Macros for Excell-they've been disabled or removed.

        Office 2004 can run VB Macros, and thus suffers from the same word macro virus variants that have been unaddressed by microsoft for over ten years.

        Office 2008 can not, and is therefor ignorant of malicious macros. However, this wasn't a planned feature; MS simply chose not to port VB for applications to the universal binary code for Office 2008. They plan to reintroduce that support in the next major release.

        Personally, I find it ridiculous that these macro viruses still exist. Seriously, why would a software company create a scripting language that can embed scripts that modify the base templates for files, let alone a scripting language that can embed scripts that embed other scripts into the base template files? What else would that function be used for than to self-propagate viruses?

        Seems like a remarkably easy corner case to trap for and block. Or at the very least, code in a function that detects these well known macros and eliminates them when opening files.

        But no.

        The windows world is so desensitized to the ubiquity of viruses, that these annoying little buggers don't even pass for a blip on their radars.

          And let's be straight on the terms of "affected" by a virus. If you get a document that keeps getting copy after copy of the same macro written to it, the file size skyrockets pretty quickly. Granted this isn't specifically harmful or malicious, but it does take up disk space and it takes it up quick for power Office users. Many of these types of viruses CAN remain active on Mac copies of office that allow Macros

            and emailing the files is likely to fail as most mail servers run antivirus and reject attachments with known virus files.

            And then there's that annoying "enable macros" message everytime you open a file.

              what does it mean to install illegal software with a keygen?

                Key generators (or keygens) are applications that are written by hackers who have reverse engineered the process by which software companies generate the codes used to unlock their software. Typically, this is used for very expensive or very popular software. The adobe suites, the latest games, high end sound production software, and of course office products all tend to get someone looking into a way to steal them.

                "illegal software" is usually completely legal software that someone has illegally copied and attempted to install using any of various methods to keep it from complaining about it not being legitimate. "Cracks" are typically applications that perform complex tasks before or after installation to alter the software and make the application think it's legit. Unsophisticated software can have serial numbers shared amongst users, slightly more sophistication prevents identical serial numbers from being used on the same net at the same time. Very sophisticated software has time sensitive keys that require a generator.

                  Yes = ClamXav ( ) That will scan your drive for various known viruses . We use it all the time . A lot of motion picture experts group threes ( .mp3's ) music contains trojans . Yet i do not think these viruses affect macs® . ..yet . Won't be long though . The other major vector for viruses in a corporate ( or home ) setting is the U S B thumb drives or memory sticks or memory cards from cameras , palm pilots & blackberries . i think you all get the picture . The biggest virus out there right now is Windows® 7.0 . . ..HAhahAHhahah & h t h ∞
