I’m not sure how taking a screen shot is gonna help him with an ad behavior.

It would need to be a video vs a screen shot. How am I supposed to screenshot user interaction on the website. You click anywhere on the screen and then a new pop up takes you to a new tab with a Toyota ad. So does he want a screenshot of his website or a screenshot of the offending website? Not sure how a screenshot of either of those things is going to help.
