Not sure what Adobe Reader message means

In attempting to open a PDF file with the Adobe Reader, I received this message:

"This document is trying to put Acrobat in full screen mode, which takes over your screen. In this mode, it is possible to present documents that look like other applications that request your personal information."

I understand what "full screen mode" is, and I do want that, but I don't understand what "In this mode, it is possible to present documents that look like other applications that request your personal information" means.

Thank you very much.

Full screen mode can take over your entire screen - very similar to running a powerpoint slide show.  In this mode, the PDF can have been created to make it look like it is a complete application in itself, eg web browser showing your banks webpageetc.  You could then be "fooled" into entering personal details into the text fields (Username and Password etc) and this could be sent to the rogue server.

It is just a warning to make sure what you are seeing on the screen is actually what you think it is.
