Jessica overhears two colleagues discussing malware. One colleague is adamant that a virus is able to self$-$propagate and most malicious programs fall under the umbrella of a virus. The other colleague attempts to explain that a virus requires human intervention for transmission and that there are many types of malware. Which colleague is accurate and why?

Question $23$ options:

Viruses come in many shapes and forms with the ability to self replicate. The first colleague is right in that all malware is considered to be a virus.

Malware is generally broken down into two categories such as a worm or virus. All forms of malware are able to self replicate.

There are no instances of malware that can self$-$replicate and a virus is a specific subset of malware.

Malware terminology is sometimes used imprecisely and is an umbrella term for many different types of malicious code. A virus is a specific subset of malware that upon infection, attempts to spread itself.
