While you guys are working on this, I have seen two situations where both Cerber and Zepto ransomware messed up two entities.

Since then, I have been thinking about how to always be ready to mitigate the effects. And the surest way is backup, backup, backup.

In situations where files are stored on shared drives on the network, the situation is even worse should the share not have a backup elsewhere.

In the meantime, this tool should help Windows users create backups -> http://www.2brightsparks.com/download-syncbackfree.html
