Partial answer...

First, I tried opening it with the Gnome PDF viewer, and it asked
me for a password, that the file was encrypted.

I downloaded the "plug in" and installed it per instructions.
I then started tcpdump, and disconnected my DSL.
Trying to open with Acrobat now resulted in a message indicating
it was unable to contact the server.

Hmm.

Someone is trying to track opening of certain PDFs on my machine.

This was from the Numerical Recipes "old stuff" web site:

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
