This is a copy of what I have received in the past few minutes. If you're unsure about how ransomware is spreading so fast then I would suggest you read the PDF file, showing us the graphs and ways of stopping it.

The War on Ransomware
Hello,

Ransomware has become our greatest enemy, and if we don't fight against these malicious attacks they will only continue to progress into something even worse. In the attached document I discuss the current war on ransomware, what PC Pitstop is doing to try and end the war, and how we need your help. I strongly encourage you to read this document, as no war can be won with one party. We need your help to end the war on ransomware, and we need it now.

Sincerely,

Rob Cheng
