AUto generated pages: Got some weird ones

SO today while googling my company’s name, I found something very odd. The second result was a page with a single image on it. THere was no content, and certainly nothing that would have caused that page to come up. Its clearly an auto generated page for an image that was uploaded long ago, but somehow is popular on google (no idea why).

Is there a way of a) finding all those random auto generated pages and b) getting rid of them?

My best guess is a long time ago somebody put this image on the site, and chose to link to the attachment page, generating this. Can I get rid of all these somewhere?

Thanks in advance
