Does anyone know what the program "ShllHiddenWindow" is on Windows?

Question

Every time I shut down my computer, a box pops up that says this program is not responding and I have to close it, but I can't find it anywhere and I have no idea what it is for. I've checked in the Add/Remove programs and there is never anything running on my task bar with that name.

If you've heard of this program, know what it is for and/or know how to get rid of it, please let me know. Thanks!

Answer 1

I did a google search, and it yielded no results for that program.
