For the third time in a month, Oracle has issued a new Java security patch. If you use Java, you need to download and then install the new version. Once you've done that you should without fail disable Java in your web browser.
With that out of the way, my primary recommendation is still to remove Java from your systems unless you absolutely need it to run a critical application. For more background on Java security problems, please read my blog post from just a few days ago.
