Re: It's nearly 2020 ...
Anti-malware is snake-oil sold to users of insecure-by-design operating systems. Have you not noticed that it so very frequently fails? Ever ask yourself why?
Durr. I'm going to go ahead and answer your question by saying that, unlike you, the malware scene isn't frozen in time and is constantly evolving - hence the need for updates, patches and bugfixes.
In this particular case, from what I can see ATTK is a free support tool and not an antivirus product in itself. The snake-oil sold to users is where exactly??
