Which of the following is NOT the type of viruses?

An “innocuous virus” is not a formally recognized type of computer virus. All viruses, by definition, are considered malicious because they replicate without authorization and potentially cause harm, whether immediate or latent.

Common types of viruses include:

Humorous (B): A virus designed to prank users without causing real harm (e.g., funny messages).

Hostile (C): Actively destructive or malicious.

Altering (D): Modifies system files or behaviors.

" Innocuous virus " (A) is a misnomer, making it the correct choice as " not " a virus type.
