WannaCry ScreenshotWanna, Wannacry, or Wcry is a new malware, or ransomware that has been spreading across the Internet over the past several days.  This threat is being transmitted as an attachment or link to a malicious file within emails.  Although we have many layers of security, monitor evolving threats, and take significant steps to ensure a strong security posture, those with malicious intent are always trying to circumvent IT security.

Sometimes our weakest link is our home computers that do not receive the proactive security services and monitoring that our work computers receive.  If you are concerned about your Windows home computer’s protection, we would encourage you to take the 4 steps below to help to help avoid ransomware and their associated problems.  If your computer is a SolutionWorx supported computer, it is not necessary to take the steps below.
