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 .
On Chrome you are having 188.8.131.52 version Flash Player as it is the latest available Chrome specific Flash Player. Can you please recheck the version of IE Flash Player. That should be 184.108.40.206 because currently that is the latest player available for IE.
