What is a Ransomware? Ransomware is a particularly vicious type of malware. Once it lands on a computer, it begins to encrypt files on the hard drive. After it has encrypted files, the program demands money from the victim, usually in the form of Bitcoin. Victims have to pay the malware authors hefty amounts of money in order to get their files decrypted.

Fortunately, many of the big names in cyber-security provide tools that help protect your PC from ransomware.

Anti-Ransomware are tools designed to help you increase the security level of your system by detecting potential threats that usually go undetected by antivirus solutions.

How We Tested? We evaluated each free anti ransomware software for ease of use, performance and reliability on our test system running Windows 10. We then obtained data from trusted sources to come up with the top free anti-ransomware list.
