Remove stored signature

How do I remove a stored signature? Although I have used the stored image of my signature, most of the documents I sign for the organization I work for I just type in my name.

I removed my stored signature image from it's previously used file location on my computer. Today I signed a document and suddenly the image of my signature pops into the field. It's never automatically filled in the signature field, if I wanted to use it I had to go get it.

I have not intentionally stored the image of my signature anywhere in Adobe Acrobat, Reader or Cloud nor can I find it in any of those apps. I will no longer be working with this organization soon and don't want my signature available for anyone else to use.

Thank you,
