I installed Avast Driver Updater, the trial version. Now, every time I shut down my Dell laptop, this message displays: "Forcepad driver tray window: Syn TPEnh.exe - Application Error." I think it has something to do with the touchpad, which I generally don't use. I would like to find out how to resolve the error so the message doesn't keep appearing. The computer has Windows 10 Pro, ver. 1511.
