Ransomware is a type of malware that prevents or limits users from accessing their system, either by locking the system's screen or by locking the users' files until a ransom is paid. It is a malware designed to deny a user or organization access to files on their computer. By encrypting these files and demanding a ransom payment for the decryption key, cyberattackers place organizations in a position where paying the ransom is the easiest and cheapest way to regain access to their files.

‍

Ransomware sometimes deletes itself after it has infected a system; other times, it stays on a device to infect other devices or files. Use antimalware/anti-ransomware. Most antimalware and anti-ransomware software can quarantine and remove the malicious software. Ask security professionals for help.
