Answer 1

Answer:

A. Malicious software

A Trojan horse (or simply Trojan) is an example of malware (malicious software). ## Key Characteristics of a Trojan * Deception: It disguises itself as legitimate, harmless, or useful software (like a free game, an update, or an attachment) to trick users into downloading it. * No Self-Replication: Unlike a computer virus or a worm, a Trojan cannot replicate or spread by itself. It relies entirely on a user manually executing it. * The Goal: Once inside a system, it opens a "backdoor" for cybercriminals to steal data, spy on users, or install additional malware like ransomware. ## How It Compares to Other Malware Trojan Horse=Misleads users by pretending to be safe. Virus = Attaches to a clean file and spreads when that file is opened. Worm =Automatically clones itself to spread across a network without human help. Spyware=Secretly records user activity (like keystrokes or passwords).
