21,0,0,213 is the latest version. Why do I have 21,0,0 216 after updating repeatedly?

I have tried repeated updates in an attempt to fend off this ransomware threat. I checked my version before updating and it was 21,0,0216. That does not change no matter what I do. I have windows 7 on both of my laptops. I use both Chrome and IE browsers. I have tried to update on both with the same result .
