Both editions of CryptoDrop are designed to quickly and accurately detect the presence of ransomware on your system. With the Free Edition, we notify you through an alert window when we suspect you may be infected by ransomware, allowing you the opportunity to put your machine into Lockdown mode, which prevents any further writes to your data files. The Fast Recovery Edition goes one step further: with our exclusive DropSafe(TM) technology, we ensure that not only is ransomware detected, but any files that may have been infected by ransomware can be quickly and easily recovered.
Other differences are that ransomware detection can occur on any directory in your system that you specify with the Fast Recovery Edition, while detection is limited to your "My Documents" folder in the Free Edition. Additionally, you are able to specify 5 rules for system behavior in the Free Edition, while the number of supported rules is unlimited with the Fast Recovery Edition.
