That being said, I believe you might be referring to "Ransomware," which is a type of malware that has gained significant attention in recent years.
Ransomware, also known as RetardWare (although this term is not commonly used), is a type of malware that encrypts a victim's files or locks their device and demands a ransom payment in exchange for the decryption key or unlock code. The primary goal of ransomware is to extort money from the victim by threatening to delete or destroy their data.
