Which of the following is one of the key features found in a worm but not seen in a virus?
A . The payload is very small, usually below 800 bytes.
B . It is self replicating without need for user intervention.
C . It does not have the ability to propagate on its own.
D . All of them cannot be detected by virus scanners.
Answer: B
Explanation:
A worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any help from a person. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided.
