I've just launched an online course after having uploaded by 30 or 40 PDFs that I converted from Word with the Microsoft Word add-in.
Students are complaining that when they download the PDFs from the course and click on a live link they get a security message that says "if you trust the site, choose Allow. If you don't trust the site, choose block".
It's making the students nervous.
I'm using Acrobat 9.5 currently.
I've never seen this before with any of my PDFs – I think this is new.
Does anyone know how to turn this feature off?
Thanks in advance!
Even though you create your PDFs with Acrobat 9.5 your students most likely use Reader X or Reader XI to open them. The message that they see is a security feature to prevent malicious PDFs from being downloaded and doing some harm. In Acrobat/Reader XI once you choose "Allow" by default it remembers it and does not ask the same question for all PDFs that come from the same domain. So, if you post your PDFs on the same site each student will see this message only once. There are ways to automatically deploy Reader pre-configured to trust certain sites but this is not that can be done on individual machines. This ability is used mostly by big companies that own the hardware and installed software.
