Another large-scale cyberattack underway

I use Norton. Over the last few days, pop-ups from them trumpet the fact that my computers, tablet and phone have been protected from WannaCry.

I don't get it. All these systems that have been compromised world wide - is it because they haven't invested a relatively small sum in protection like Norton?

I thought it was because of Windows updates (or lack of) that computers were hit.
