Question

Quizplus · Accepted Answer

A Trojan program typically installs a backdoor on a computer to provide unauthorized access to an attacker. A rootkit is a type of backdoor that can hide the existence of the attacker's presence on the system. Therefore, A is the best choice. B, C, and D are incorrect because a shell refers to a command-line interface, a worm is a self-replicating program, and a macro virus infects documents, not computers directly.
