Security Update 2011-003 released by Apple, kills MacDefender

Update: This software update — as promised by Apple — locates and removes variants of the MacDefender program if present. Also, File Quarantine will now check with Apple daily to download new security definitions, so the company should be able to respond to threats much quicker.
