Microsoft’s antispyware team made version 1.0.509 available for download a couple of hours ago. You can use Help > About to see what you’re currently running, but unless you’re another Microsoftie with the latest internal bits, you probably don’t have this one yet :-)

The only time I notice I’m running it is when it warns me about the latest piece of facehuggerware trying to install some autorun entry. Ahhh, Apple Quicktime, what would we do without you?

Anyway, two thumbs up. Get it while it’s hot:
