Email from admin@hotmail regarding past due invoices?

I just recently received an email from admin@hotmail that simply states that I have past due invoices with a PDF attachment. I do not know of any reason that I would be receiving an invoice from hotmail and I don't want to open the attachment in case it is infected with a virus. I am assuming it is a hoax but would appreciate it if anyone could shed some light on it for me.
