Ransomware Protection

Ransomware is designed to block access to a file or computer system until a sum of money is paid. Personal ransomware attacks are on the rise. These threats can slip by traditional web filters and antivirus defenses, encrypt your personal documents and photos, and then demand you pay a ransom for the decryption key. One of the fastest growing forms of cybercrime, ransomware has become so lucrative that some criminal organizations have begun to distribute ransomware toolkits to assist small-time hackers in building their own ransomware. Sophos Home watches for ransomware and ransomware-style behavior, allowing it to catch brand new variants that other security software can’t recognize. If malicious encryption is detected, Sophos Home stops the process. It then rolls back any changes made by the ransomware by replacing the encrypted files with saved backups, and then removes the ransomware. All of these processes occur without any required user intervention.
