Snow Leopard Antimalware Feature Gaining Publicity [Updated]

As we briefly mentioned yesterday, antivirus vendor Intego notes that it has received multiple tips that Apple's forthcoming Snow Leopard operating system appears to contain at least some rudimentary antimalware capabilities. According to screenshots of warning dialog boxes submitted by Snow Leopard users, the operating system is able to warn users that a downloaded file contains malware, specifically the OSX.RSPlug.A Trojan Horse first discovered in October 2007.
We're not sure yet exactly how this works, but the above screen shot shows this feature working with a download made via Safari, detecting a version of the RSPlug Trojan horse in a downloaded disk image.
MacRumors received the first report of this Snow Leopard feature in February 2009, soon after the release of developer build 10A261. But while the feature appears to have been present in Snow Leopard builds since that time, little is known about the functionality and from where Snow Leopard is drawing its information for identifying malware.Intego's posting regarding the feature implies that Apple is not licensing the information from that company, while ZDNet has confirmed that Apple is not using the open-source ClamAV engine. It is possible that Apple is licensing the functionality in part from another commercial antivirus company or developing its own system, but Apple has not revealed any details about the feature on its extensive security page for OS X Snow Leopard, referring only to the existing standard scan of downloaded files to determine if an application is included in a given package.
Update: The Register notes that Apple has simply included information on two Trojan Horses, OSX.RSPlug.A and OSX.Iservice, in one of Snow Leopard's system files, identified to MacRumors as the following:
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.plist
While Apple could certainly update this file with identifying information for new threats that arise in the future, there does not appear to be a full-fledged antivirus package with regularly-updated virus definitions deployed in Snow Leopard.

(View all)EDIT: It seems like a good thing to me -- the only caveat is that, were there actually to be a proliferation of malware, no one knows what Apple's update scheme is, etc, and it could be very confusing who is and who is not protected and from what....
Very interesting... I'm surprised no one has been able to crack what they're doing. After they put Clam into OS X Server, I almost thought they might eventually roll it out as a component of OS X, even though there's little need. Anyway, nice to have what little one needs in the way of anti-malware right in the package. :)

There won't be a proliferation of malware - because Macs simply don't get virus', trojans, or suffer from malware like Windows machines do ... right? :rolleyes:
Apologists will hail the news as a great proactive approach by Apple. The rest of us are wondering why Apple even bothered - considering how "in your face" Mac enthusiasts are about not being susceptible to malware - which is, of course, false.
I agree with mkrishnan on the updating scheme of things.
Time for a new ad campaign.:D
Exactly...
No one with knowledge about macs has ever denied the fact that macs get viruses. It is just a marketing strategy of Apple to say they don't get viruses. But the fact is they are not effected by the same viruses that inflict damage on Windows systems.

Don't know what a virus is, do you?

And they'd be sued if they were lying.
