If you’re still poking along with Mac OS X 10.5 “Leopard,” Apple has finally gotten around to offering a Flashback Removal Security Update you might want to download.

Flashback is OS X malware which was first discovered late in 2011. It made headlines again in April when a Russian antivirus software developer discovered a new variant of it that exploited an unpatched vulnerability in Java. Apple has since closed the hole and provided a Flashback removal tool for newer versions of Mac OS X, but this will help the few remaining users still working with 10.5 to make themselves more secure.
