Which of the following malware types may require user interaction, does not hide itself, and is commonly identified by marketing pop-ups based on browsing
habits?
A.
Botnet
B.
Rootkit
C.
Adware
D.
Virus
Explanation:
Adware is free software that is supported by advertisements. Common adware programs are toolbars, games and utilities. They are free to use, but require you to
watch advertisements as long as the programs are open. Adware typically requires an active Internet connection to run.
Incorrect Answers:
A: A botnet is a collection of Internet-connected programs communicating with other similar programs in order to perform tasks. This can be as mundane as
keeping control of an Internet Relay Chat (IRC) channel, or it could be used to send spam email or participate in distributed denial-of-service attacks. A botnet does
hide itself, but is not commonly identified by marketing popups. Therefore, this answer is incorrect.
B: A rootkit is a stealthy type of software, typically malicious, designed to hide the existence of certain processes or programs from normal methods of detection
and enable continued privileged access to a computer. A rootkit does hide itself, but is not commonly identified by marketing popups. Therefore, this answer isincorrect.
D: A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also
replicate themselves. All computer viruses are man-made. A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even
such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one
capable of transmitting itself across networks and bypassing security systems. A virus does hide itself, but is not commonly identified by marketing popups.
Therefore, this answer is incorrect.http://techterms.com/definition/adware
