Please Be Advised:
A potential vulnerability which, could allow a hacker takeover or intrusion via Internet Explorer 7, 8 or 9, is being addressed via an Important Automatic Update on Friday, Sept. 21, 2012. This is an out-of-cycle FIX to deal w/ the issue immediately. End Users should have machines set to receive Automatic Updates. However, if you do not (and even if you do) or, wrongly, have your machine off @ night, make sure, Friday (21/9) or Saturday AM (22/9) that this Update is put in or has been installed.
This is IMPORTANT!!
Please, exert due diligence regarding to this matter and w/out delay.
The issue does not affect IE10
