What is Ransomware? Is it 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, unless a ransom is paid?

Ransomware can lock access to both specific files and entire systems. It achieves this by encrypting the files and demanding a ransom in exchange for the decryption key. This can effectively render the entire system or specific files inaccessible until the ransom is paid or alternative solutions are employed.
