Seems a known flaw in IE that the Gang at Microsoft has not fixed yet has gotten the attention of the MOB and they are hacking mainstream websites and placing the payload on their web pages thus infecting your PC as you drive by.
This flaw is serious in that all you have to do is load the web page and they own you. My advice to everyone is flip your middle finger at Microsoft and go over and install Mozilla Firefox. I switched and I’m never coming back. [ZDNet][Slashdot][The Register] [Techdirt]
