Apple has announced that it is working on a tool which will detect and remove the Flashback malware which is thought to spreading across a significant number of Mac computers. The malware, thought to have infected in excess of half a million Mac computers worldwide, has become an aggressive target for Apple as they work to issue a fix and disable the malware command and control network by working with ISPs.
In an announcement via a support document on the Apple website the company noted that they had already released an update to fix the Java security flaw for systems that run OS X 10.6 and 10.7. For users that are running OS X 10.5 or earlier, the company advises that users can protect themselves by disabling Java in the web browser preferences to prevent infection.
Infection with the Flashback malware can also be prevented by running programs like ClamXav and Little Snitch on your system, both of which prevent the malware from installing correctly.
