Someone else's name attached to document

A couple years ago, I created my resume on a friend's computer because she was helping me.  I sent it to myself and have been working on it ever since.  When I save it as a word doc, my name is attached to it.  But, when I save it as a pdf, and I open it up in adobe acrobat reader, her name is at the top of the document tab, as well as at the top of adobe.  I even created an account with adobe, signed in, and re-opened the pdf and I still have the same issue.  I am not sure how her name is still attached to this pdf. I have tried to copy and paste the resume into a new document and resave it, but unfortuantely that changes the format of my document, so no luck there.
