Apple Updates Malware Definitions

Remember that PDF based trojan I reported on just 3 days ago? If not, there's a link, I recommend reading that story first, getting mildly frightened, and then coming back here for comfort.

Okay, don't be frightened, Apple has already issued an update to the built in malware definitions in Mac OS. That means, without knowing it, your Mac has already updated and protected itself against this trojan. Of course, this is only available to users of Mac OS Snow Leopard or Lion. But that's just another reason to upgrade. Lion has far better security than it's predecessors, even Snow Leopard. So, if you're really worried about security, upgrading to Lion would be your best bet.
