Free anti-ransomware software with signature-based detection, monitoring program behavior and processes for suspicious activity
CryptoPrevent is a free anti-ransomware program designed to protect Windows computers from ransomware attacks. It uses signature-based detection to identify ransomware-like behaviors from programs running on the computer.
When installed, CryptoPrevent runs silently in the background and monitors all program activity and behaviors. It has a database of known ransomware signatures that it checks program processes and behaviors against. If it detects suspicious activity that matches ransomware signatures, it will automatically intervene and stop the process to prevent file encryption.
CryptoPrevent monitors things like attempts to change specific file types to read-only status, rapid encryption of files, changes to file extensions to match known ransomware appended extensions, and communication with command and control servers. It quarantines suspicious files and behavior so that it cannot further infect the system.
As a lightweight, always-on protection tool, CryptoPrevent serves as an important layer of defense to complement antivirus software. It provides ongoing monitoring that immediately responds when ransomware behaviors are detected. Regular updates ensure detection signatures stay current as new ransomware variants emerge.
