You seem to be a bit confused. It's not telling me there's a new update. It's a daily popup which says "a message from the founder of malwarebytes" and links to this website - https://www.malwarebytes.com/why-upgrading-matters-ceo/ - which is an advertisement for the premium version of malwarebytes. From malwarebytes' definiton of adware: "What is adware? Adware is unwanted software designed to throw advertisements up on your screen, most often within a web browser". This is clearly therefore adware and I would like to disable it.
