Korean security vendor Hauri have just released a beta version of ViRobot Anti-Ransomware. Translated with Google Translate: The website is in Korean, but the software has some English language text.
At this stage of development it is not worth further discussion. The newest version (1.1.0.5 if I remember correctly) didn't even stop the ransomware samples that I use as controls (old Tesla, CTBlocker).
@cruelsister Thanks for the information. Yes, 1.1.0.5 is the latest version. I'm going to keep in installed, as I so no harm in doing so.
