There is a Vulnerability in Graphics Rendering Engine in IE which can allow Remote Code Execution. You can read more about it at http://www.microsoft.com/technet/sec...ry/912840.mspx
Recently my friends site got hacked and some other sites like hedir.com also got hacked, we have discussed the issue in detail at http://www.webproworld.com/viewtopic.php?t=58553
I have corrected my friend's website and I have blogged the steps at http://www.ajimathew.grmtech.com (please deactivate the link if it is against the policy).
Since this is currently very active worm so thought of blogging the solution. YOU ARE MORE SAFER IF YOU ARE USING FIREFOX.
Enjoy Viruses with IE,
