Explanation

A Trojan (Trojan horse) is malware that disguises itself as legitimate or useful software to trick users into installing it. In this scenario, the keygen appeared to be a software activation tool, but it secretly carried malicious code. This is the defining characteristic of a Trojan. It is not a worm (which self-replicates and spreads across networks without user action), a logic bomb (which lies dormant until a specific trigger condition is met), or adware (which displays unwanted advertisements). The combination of a deceptive delivery mechanism (fake utility) and hidden malicious payload makes this a classic Trojan.
