I've used Ashampoo's Burning Studios for years and usually get the latest version cheaper. OK. you'll get a few emails for newer products now and again but I wouldn't class as spam as you can unsubscribe if you wish. One of the better companies in my humble opinion. Just to be clear Ashampoo is a client of cleverbridge which is an E-commerce company. In this link there is an interesting case study of how they worked with Malwarebytes. It's a PDF file.
