Thanks. But am I safe? And how might I find that out? The article you cite (dated 2 days ago) has contradictory statements, one on top of the other: "... in most cases Mac users should be relatively safe. Starting with OS X 10.7 Lion, Apple stopped including a Java runtime with OS X, so if you have purchased a new system with OS X 10.7.0 or later, or have formatted and reinstalled Lion, then you will, by default, not be affected by this malware. "However, if you do have Java installed on your system, then for now the only way to prevent this malware from running is to disable Java."
According to my iMac, it came from Apple with both 64-bit and 32-bit versions installed: Java SE 6 v 1.6.0_29-b11-402.
