More on the Internet Explorer bug...

Meanwhile...This vulnerability is made possible by Adobe Flash, and that is an ActiveX control, so if you enable ActiveX Filtering and go into Control Panel, and remove Adobe Flash from your installed programs list, you will be safer. I can't tell you this is a 'cure', but it certainly is better than not doing anything. Here's a snipping from an Adobe Forum page about this filtering.

The remarks above for I.E.9 will also apply to newer versions most likely.
If you get rid of Adobe Flash, and enable that ActiveX Filtering to stop ActiveX on web pages, you should be safer. And you will be even safer if you use another browser until Mighty Microsoft issues a fix.

Note: After you have removed Adobe Flash using Programs and Features in Control Panel, navigate to your C:\Users\yourname\AppData\Local folder and remove the Adobe folder and its contents. Then while still in your AppData folder, go into its Roaming folder, where you will find another Adobe folder containing a complete copy of the Flash Player. Be sure to delete that also.
Then, go into Control Panel -> Internet Options, and scroll down to the Security section. Make sure there are check-marks in the boxes in front of:

* Empty Temporary Internet Files folder when browser is closed.
* Enable Enhanced Protected Mode.
* Enable memory protection to help mitigate online attacks.

If you had to add a check-mark to any of those, do a restart of your computer to enable that feature.

I use this, and I know some of the experts say we shouldn't use a registry cleaner, but this has worked well for me for a long time, and it gets rid of a lot of junk from several places, not just the registry. It is updated quite frequently, and has been steadily improved over the years. This is one of my favorite 'freebies'.
