GridinSoft Anti-Ransomware will help prevent cryptolockers and ransomware from encrypting your files.

This utility is designed to actively stand guard 24/7 against incoming attacks alerting you immediately to any threats and then stopping them from attacking your files, etc.

GridinSoft Anti-Ransomware sits silently and out of the way in systray while active and you can easily turn it on/off with a single click. The one thing that hopefully will be added in future versions is to provide details about what types of ransomware, etc., it blocks.
