Here is an interesting security tool which might be
worth a look.
Description from SnapFiles:
Cybereason RansomFree is a security application
that protects you from ransomeware, which are malicious programs that encrypt
the files on your computer, making them inaccessible, and demand a ransom
payment to restore access. Cybereason RansomFree watches the way
applications interact with files, and when it detects ransomware behavior, it
stops it immediately before the files are encrypted. The application uses pure
behavioral detection techniques and does not rely on malware signatures. Once
you install RansomFree, you are automatically protected, there is no interface
and no configuration options other than a tray icon that indicates that the
protection is active.
