Remove Flashback Trojan from Mac OS X with New Software Update from Apple

Flashback Malware Removal

Apple has released a new Java security update that automatically removes the most frequently occurring variations of the Flashback trojan malware. The software update is recommended for all Mac users to install, even if they have previously checked their systems for infection.

To get the update and remove any malware that is potentially on a Mac, simply download the “Java for OS X 2012-003″ update from Software Update found within the  Apple menu. There is no manual checking or removal required, simply installing the update from Apple resolves any potential infection for you.

The new Java update also disables automatic execution of Java applets, providing further security against potential threats down the road. Release notes are as follows:

This Java security update removes the most common variants of the Flashback malware.

This update also configures the Java web plug-in to disable the automatic execution of Java applets. Users may re-enable automatic execution of Java applets using the Java Preferences application. If the Java web plug-in detects that no applets have been run for an extended period of time it will again disable Java applets.

This update is recommended for all Mac users with Java installed.

For details about this update see: http://support.apple.com/kb/HT5242

All Mac users should install the update as soon as possible. For extra protection, don’t miss our recent post on some simple tips to secure Mac OS X from viruses, malware, and trojans.

      No, the new update secures Java from Flashback. Keeping it disabled could prevent against theoretical future attacks, but it is unknown.
