Apple has released its second update in two days to the OS X implementation of Java. The first update closed a vulnerability that has led to the infection of more than 600,000 Macs via a trojan horse. The infections have received increased media attention in the past day, including a splashed headline on the Drudge Report.
While yesterday's Java for OS X Lion 2012-001 update closed the vulnerability in Java 1.6.0_29, there's no indication what the new update -- called Java for OS X 2012-002 -- fixes. The update notes link to the same support document as update 2012-001.
Last year, Apple introduced a security update to OS X that would automatically remove malicious software from OS X installations. It isn't clear if the infected machines can be fixed via the internal OS X security mechanisms.
In OS X Mountain Lion, the next version of the OS X software that will be released this summer, Apple will include a feature called Gatekeeper. The new system relies not only on Mac App Store distribution as means of vetting apps, but also on a new "identified developer" program under which developers distributing their applications outside of the Mac App Store can register with Apple and receive a personalized certificate they can use to sign their applications. Apple can then use that system to track developers and disable their certificates if malicious activity is detected.

By the way, laws of computing 101: The OK button agrees to something, the Cancel/close window button disagrees. If you click OK, know what you're saying OK to.
EDIT: In other words, stop using it to close windows.
To find out if you're infected, do this:

In terminal run:

You should get this error:

The domain/default pair of (/Applications/Safari.app/Contents/Info, LSEnvironment) does not exist
Then run:

defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES
You should get this error:

You can copy and paste the two commands into Terminal. To open Terminal, go to Finder>Applications>Utilities>Terminal. Double click on Terminal. Hit enter after each command.
Just be careful when using Terminal. It's one of the few places where you can really mess up your computer.
