Photogallery error

Hi,

Lately, when I start my PC, I get a pop up that says “Please wait while Windows configures ‘Photogallery'” (one word). Then a dialog asks me to insert disc into D:/ drive to reinstall software. When I ignore the error, it loops 3 times, then disappears.

I don’t have the disc, because I never installed it. A search of the hard drive resulted empty for the word “photogallery.” I’ve been downloading some software recently, and wonder if a virus has attached itself to a file?
