what the heck is this?

Sometimes when I am working, usually navigating folders in explorer but I don't really know what causes this (look at the pic) thing covering my desktop. If I right click on its button in the taskbar nothing happens, no menu or anything. If I go win+D it will minimize but then once I open another window it comes up. I have no idea how to get rid of this without logging off.

Anyone have any ideas?

press ctrl-alt-del to open the taskmanager and see the name of the process that belongs to the window.
it might be spyware or a virus

I've tried that, I can't figure out which process it is

in the task manager go to the applications tab, right click on the icon for the program and select 'go to process'

also you can try this great freeware. its basically a supercharged taskmanager
