the pc (running vista) of the company president here keeps getting this pop-up:

Attachment 12169

this one refers to a "tray/app" disk but i've seen another one refer to "market research" one. he swears he doesn't install anything but i know he does (he has four desktop icon shortcuts to dropbox, a "post-it" creator, etc and god knows what else).

i've looked in the programs folders but nothing that jumps out at me. windows and virus update are current. i've threatened to do a disk wipe and reinstall windows, etc but that would take his pc our of commission for a day or two. he, of course, objects.

has anyone seen this or have any idea what it might be?

thanks in advance,

terry
