Windows 7: What causes the dialog box & # 39; Process outgoing process & # 39; when it goes off?

Over the past few days, I've noticed that a dialog box appears & # 39; Process Excited Process & # 39; every time I go to turn off my laptop. Any idea what this is and how can I remedy your problem?

I have had the laptop in question for several years, where this dialog box has never appeared before.

I'm not sure if the problems are linked, but since this dialog box has appeared & # 39; Process Excited Processes & # 39; some iPlayers of the stations do not work on my laptop. I test iPlayers on other computers, where they work well.

Any ideas about what is causing this error message and how can I solve the problem?
