Windows 7 / Office 2010 - If I receive an zip attachment and open it. When dragging it to my desktop (the contents of the attachment) - I get a dialog box "These files might be harmful to your computer" - Your internet security settings suggest that one or more files may be harmful. Do you want to use it anyway?"
It then deletes the file automatically of my desktop.
How do i prevent the dialog box from coming up / turn of that security check.
