Option to automatically run Quick Scan before shutdown

I use NIS 2011 and always run Quick Scan manually before shutting down my computer.  This is to make sure that I have deleted all tracking cookies (and other common threats) before shutting down.

 

It would be much more convenient if NIS had an option to automatically run Quick Scan whenever the user shuts down their computer (e.g. presumably by intercepting the "Start...Turn Off Computer" command (in Windows XP)).  It could be a simple Yes/No option somewhere in "Settings".

 

Any chance that this could be considered please?
