This article describes how to apply the latest security update to patch the Wannacry Ransomware vulnerability. 

WannaCry malware is a Trojan virus called Ransomware. It works by encrypting most or even all of the files on a user’s computer. Then, the software demands that a ransom is paid in order to have the files decrypted.
