There is another piece of malware targeting Mac users called SabPub, but before you panic, there’s something you should know.

If you installed Apple’s latest Java updates, you’re safe from Flashback and the new SabPub malware. The updates are available through the Apple’s built-in Software Update system in Mac OS X.

Flashback had infected 600,000 Macs, but that number has decreased to about 140,000, according to Symantec. The security company says they expected greater decreases, but you can’t force people to update their computers.

Ultimately, Apple has to rely on its users to check for updates and apply the latest software when they’re available.
