I have a process that is triggered when a user uploads a document to a document library.

I would like to be able to terminate the process if the document is deleted from the library, as otherwise I end up with processes running on documents which no longer exist.

Can anyone tell me how to do this?

An alternate solution may be to prevent users from deleting items from the document library? I'm not sure how I can do this either?

If anyone has any ideas on the best solution for this, I would love to hear them.

Thanks in advance!
