Determine which Flash version you have


To determine which version of flash is installed on a particular browser, navigate to http://kb2.adobe.com/cps/155/tn_15507.html and view the flash element on that page. Yes, if you have Flashblock on, you'll have to view the flash element, sheesh.

There's an exploit going around that affects older versions of Flash. If you haven't upgraded to the latest, go ahead and do so now.
