Which statement defines a Virus?

• B. A Program That Copies Itself Repeatedly
• C. A Program That Hides in a Computer and Allows Remotely Take Full Control
• D. A Program That Claims to Rid Your Computer of Viruses but Instead Introduces Viruses onto Your Computer

Answer: (A)

A computer virus is damaging software designed to spread by infecting other programs or files and to cause harm when it runs. The description given captures both the infection aspect and the resulting disruption to how the computer operates, which is the essence of a virus. The other statements describe different kinds of malware: one refers to self-replication in a generic sense (which could be a worm rather than a virus), another describes a backdoor or remote-access program that gives control, and the last describes rogue software that pretends to remove viruses but actually introduces them.
