Two days after their initial announcement and on the heels of F-Secure’s removal tool, checking Software Update on your Mac should prompt you for Apple’s latest Java update for OS X. The 2012-003 update removes common variants of the Flashback trojan, as well as disabling automatic execution of Java applets. While you will be able to turn the ability to run Java applets back on through the Java Preferences app, it will automatically be disabled if you don’t consistently access or run applets after a period of time.
For more information, you can read the support article or the supplementary information provided through Software Update.
