You can also try 360 Document Protector the Ransomware Terminator.
Although it does protect the Documents well (and is interesting as the backup process only initiates when malware tries to screw with the doc's) and all encrypted stuff can be restored, note that this application is ONLY for the Document folder so will have less utility and is certainly less mature than the Backup/Restore solutions promoted by AppCheck and RanStop.
Some more details at this thread regarding efficacy and extensions, for people interested in trying the app.
