Following two independent Java security updates and one last patch to detect and remove the Flashback trojan, Apple has released another software tool for getting rid of Flashback on a Mac running OS X Lion without Java installed.
Flashback is the name of a virus that was able to infect a Mac and link it up to a botnet of around 600,000 other Macs. If you’ve updated your Mac with the latest Java patch, you should be fine, but Apple has provided this new tool for safe measure to Mac users running Lion without Java already installed.
