Question

Quizplus · Accepted Answer

A Trojan horse is a type of malware that appears harmless but contains hidden code that can cause harm to the system or steal sensitive information. Unlike worms or mobile code, a Trojan horse relies on the unwitting user to execute it, typically by disguising itself as a legitimate program or file. Spyware, on the other hand, is a type of software that collects data from a computer or device without the user's knowledge or consent, but it does not typically involve hidden code or harmful actions.
