Called The GoldenEye/Petya ransomware exploit, the newest version of ransomware is nasty and dangerous. Consider that one of the affected systems is the radiation monitoring system at Chernobyl. Ouch. You need to know how ransomware works, and how to prevent it from affecting your systems at home and at work. This two minute video will get you started. Once infected, this new version encrypts not only all your data; but, also your NTFS structure so the computer won't even boot. You are responsible for your own first line security. Update all of your software today. Install one of the new ransomware detection software programs. Don't download links in email that you don't know are coming, and backup your system often and regularly. Be careful out there.
