It's no secret that i am biased toward Ransomoff myself mainly because I been testing the dickens out of it since it first landed the forums and found it quite a formidable addition as an Anti-Ransomware with amazing additional useful feature set. In my tests with Windows 10 which I installed to Legacy Disk the MBR Protection was solid. I threw Goldeneye + Petya and some other MBR Infectors at it and it stood up to them. I did D/L Kaspersky ART for Business and am anxious to see what it is but haven't yet tested it. Other's can better weigh in on how well or not Kaspersky is proved to be for them.
There is a free MBR Filter available from Cisco Talos but one can achieve more effective protection with SRP. If it can't run, it can't change the MBR and MFT. Period.
