Free Flashback Checker app for Mac security

Panic has spread around the Mac user community like a, well, virus since news broke last week of the Flashback malware that has supposedly infected over a half million Macs around the world.

The Flashback malware exploits a Mac Java vulnerability.

Apple has released an update to patch those flaws, after the Flashback malware had already infected more than half a million Macs.

Now there’s a quick and easy way to check whether your Mac is infected by Flashback, courtesy of a free app called Flashback Checker.

Where to download Flashback Checker

Flashback Checker is a small utility from programmer Juan Leon. It combs through your Mac’s contents to find any traces of the Flashback malware.

Leon used the Terminal scripts highlighted by Macworld contributor John C. Welch to write a native application that checked for all the known variants in a single run.

“People were struggling with the command line,” explained Leon to Macworld.

When you launch Flashback Checker, you simply click its one button “Check for Flashback Infection”. I

Almost immediately you get the results, and most will see the reassuring message “No Signs of infection were found.

If you are infected, the utility alerts you but doesn’t remove the malware. It does, however, direct you to information about cleaning up your system.

This does require getting intimate with the Terminal command line interface.
