Friday's patch doesn't <i>fix</i> the problem, but just puts a well, patch on IE. The exploit still exists, the patch just disables what is used to exploit it: the ADODB.Stream ActiveX Control.

Think of it as using a bike and you realize there's a leak in your tube. MS keeps giving you patches for your tube for each time you find a hole. It kinda works, but eventually, you need to replace the tube altogether.

There's even an <a href="http://slate.msn.com/id/2103152/">article on MSN</a> about ditching IE.
