Question 19: Several users' computers are no longer responding normally and sending out spam email tothe users' entire contact list. This is an example of which of the following?
A. Trojan virus
B. Botnet
C. Worm outbreak
D. Logic bomb
Correct Answer: C
Explanation:
A worm is similar to a virus but is typically less malicious. A virus will usually cause damage to the
system or files whereas a worm will usually just spread itself either using the network or by sending
emails.
A computer worm is a standalone malware computer program that replicates itself in order to spread
to other computers. Often, it uses a computer network to spread itself, relying on security failures on
the target computer to access it. Unlike a computer virus, it does not need to attach itself to an
existing program. Worms almost always cause at least some harm to the network, even if only by
consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted
computer.
