Attempt to install software for “Non-Plug and Play Drivers”.

Once or twice a day there appears on my monitor a small window with the label “Hardware Installation” and the headline “The software you are installing for this hardware: Non-Plug and Play Drivers has not passed Windows Logo testing”, etc., followed by a warning from Windows. I dismiss the window by clicking the “STOP Installation” button, but after a while it comes back.

Who or what is doing this? What should I do about it? Is there anything I can do to put a stop to it? My operating system is Windows XP Professional. All my peripherals seem to be working.
