Windows 7: How do I get one program shutting down to auto shut down another?

I'm new here and believe me I have searched for an answer, but if someone could point me to where I might find one I'd appreciate it.
My VPN network has a habit of disconnecting me at odd times while I am sending files and my computer automatically then reconnects me directly thru my IP provider Comcast which is not as secure as I'd like.
Is there a way to have the shutting down of one program (VPN) automatically shut down another (TeamViewer etc)?
I read today about programs such as KillIt? but could not find much info on its working that is within my limited expertise.

Thanks

You could go to Event Viewer and find the entry that gets created when your VPN shuts down. Link that specific event with a Task you would create that performs the action you want the machine to take. That way every time that event occurs it should automatically launch your task and execute the action you specify.
