Ransomware is a type of malicious software, or malware, designed to block access to a computer system until a sum of money is paid. A new ransomware subset is called crypto-ransomware, which encrypts certain file types on infected systems and forces users to pay a sum of money to obtain a decryption key.
It’s a significant problem that’s on the rise, and if infected, it should be combatted as soon as possible. There are many ransomware variants—here is a list of known variants and their extensions.
