You should be able to remove security by opening the document, then going to File > Properties > Security Tab and changing the Security Method to "No Security". Then resave the file (probably with save-as).

I have the same problem, and when I save as the file to another name, the security is saved with the new file as well and I can't get rid of it.

Please Help me.

You can simply use PDF Security/Protection/Restriction remover packages to remove all signatures and restrictions.
