Apple has released its second Java update in as many weeks to stop the spread of the Flashback malware on OS X systems.
The company said that its Java update for OS X 10.6 and 10.7 systems would specifically seek out and eliminate the malware which has been plaguing Mac users in recent weeks.
The two-piece update will first run a scanning and cleaning tool.
The malware removal program will scan for the common variants of the malware and notify users if an infection is found.
The company noted that users will not receive an alert message from the tool if Flashback is not detected on their systems.
The second piece will bring a policy change which the company refers to as a "hardening measure" for Java.
The updated software will place new restrictions on the Java browser plug-in and the Java Web Start tools which will shut both components off should they remain inactive for a period of 35 days or more.
Once disabled, the components will prevent the automatic loading and execution of Java applets within browsers. Users will be able to re-activate the components through the OS X Java Preferences control.
The updates mark Apple's second attempt to stop the spread of the Flashback malware.
Last week, the company issued an update to patch the Java vulnerability being targeted in drive-by download attacks on users.
The banking Trojan continued to spread, however, with infections estimated to have climbed over 600,000 systems. Security vendors have joined in on the effort as Kaspersky released a scanning site and cleaning tool of its own to take down the infection.
Apple has also been said to be targeting the online network used by Flashback. Security firm Dr Web said that the company requested that an internet service provider shut down its research servers in a possible case of mistaken identity.
