Need to disable the AdobeSign in Adobe Pro installations

This is all that management has given me to work with is this single statement.  I do not have an Adobe Pro license for myself, but I can pull one from one of my users, if necessary.  So I guess there is something in Adobe Acrobat Professional that allows you to sign documents?  We are wanting to change this or remove it, so that we can use a different program.
Thank you in advance for any help you can give me.  Also I apologize in advance for the limited information.  If anyone wants to know more, then I will kick it back up the chain to see what I can find out.
