NIS Vulnerability Protection Crashing IE9

Today I was unable to start IE9 (on Windows 7 64-bit) because it kept crashing on startup.

 

The error message is as follows:

 

"Internet explorer has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

"A problem with this web page caused internet explorer to close and reopen the tab. IEframe.dll is not responding."

IE9 then tries re-open & crahses repeatedly. I had to use Task Manager to kill IE.

 

After starting IE9 in no-addon mode and enabling addons one by one I identifed that NIS Vulnerability Protection is the addon causing the issue.

 

The problem has not occurred prior to today.
