I installed this on my wife's sister's and friend's computers. A couple of weeks later BitDefender issued an updated version. Unfortunately BitDefender AntiRansomware does not auto update itself, the installed previous version stopped working and the manually downloaded update would not install until the previous version had been uninstalled. They were left without protection from ransomware. BitDefender AntiRansomware is clearly not suitable for numpty users who lack on-the-premises support. I am looking forward to the MalwareBytes AntiRansomware production release. Meantime, the beta version fills the protection gap.
