I have downloaded my bank statement and saved it to my computer. The file name has the word (SECURED). I can open the the saved statement without a problem. But since the statement is saved to my computer, I would like password protect the statement not open without entering a password.
I can't do that because I don't know the password for the statement. I ever called the bank and which they said to call Adobe.
You can't remove it with Acrobat (or any other Adobe software) if you don't know the password. You can use Acrobat to create a security envelope. When you do this the document is included as a file attachment to a document that you secure with a document open password. For example, to do this in Acrobat 9 you'd select: Advanced > Security > Create Security Envelope
You can add as many files as you want to the envelope document.
It's quite possible that the password is unknown and unknowable, and the security permanent.
