Apple's "known bad" Xprotect file is now automatically updated

Very technical term I used there in the subject.. I know.

Apple just released Security Update 2011-003, in which they check for the MacDefender Malware, which I wrote about here.  But the most interesting part of the update is this paragraph:

File Quarantine
Available for:  Mac OS X v10.6.7, Mac OS X Server v10.6.7
Impact:  Automatically update the known malware definitions
Description:  The system will check daily for updates to the File
Quarantine malware definition list. An opt-out capability is provided
via the "Automatically update safe downloads list" checkbox in Security Preferences. Additional information is available in this.
Knowledge Base article: http://support.apple.com/kb/HT4651

Where apparently, Apple has built in an automatic updater to their anti-malware file, in it's most basic form, giving Apple the ability to directly protect their OS against the newest Malware.

If you don't know what I am talking about when I say "anti-malware file"  I suggest you read this post as well.
