That is not a valid file format. I have a feeling that someone installed Pretty Good Privacy on that computer and encrypted the database. This is what I found on the Internet:
What is a PGP file? Security key or digital signature file that verifies a user's identity; used for decrypting a file encrypted with Pretty Good Privacy (PGP) software; ensures that protected files can only be opened by authorized users.
Do a search from the Start menu for *.pgp to see how many files are encrypted and then find out who did this to un-encrypt the files.
I'm also wondering if there is a Trojan or virus that is doing this to files too. I did search the Internet to see but didn't see any reports yet.
