Unfamiliar dialog box re: Be Careful! Document may contain personal information. What should I do?

[OaklandJim]

I downloaded a file from someone on the list asking for help. Before saving I'm getting a dialog box that I've not seen (attached). As far as I can tell -- after looking at document information -- there is no personal information, of mine anyway. What should I look for to get rid of this dialog box?
