Microsoft has released an out-of-band security patch for Internet Explorer versions 6 through 11. If you do not have Windows Update enabled and set to Automatic, please make sure to do so. You can confirm if the patch has been applied to your system by running the following from the command line.
wmic qfe | find 2964358
If the result of that command outputs nothing, you are not patched.
