CRansomware

Ransomware is a type of malware that encrypts a victim's files and demands payment for their release, but its primary function does not involve self-replication across systems.

DTrojan horse

A Trojan horse is malware disguised as legitimate software that tricks users into executing it to gain unauthorized access or perform malicious actions, but it does not self-replicate like a virus or worm.
