A user has several random browser windows opening on their computer. Which of the following
programs can be installed on his machine to help prevent this from happening?

A.
Antivirus

B.
Pop-up blocker

C.
Spyware blocker

D.
Anti-spam

Explanation:
Pop-up blockers prevent websites from opening new browser windows without the users consent. These
are often used for advertisements but can also be used to distribute malicious code.
Incorrect Answers:
A: Antivirus software is used to protect systems against viruses, which are a form of malicious code
designed to spread from one system to another, consuming network resources.
C: Spyware monitors a user’s activity and uses network protocols to reports it to a third party without the
user’s knowledge or consent. This is usually accomplished using a tracking cookie.
D: A spam filter is a software or hardware solution used to identify and block, filter, or remove unwanted
messages sent via email or instant messaging (IM). It does not block random browser windows, which are
pop-up windows, from opening.
