Which of the following software displays advertisements, whether or not the user has consented?
A.
Trojan horse
B.
Spyware
C.
Adware
D.
Honeypot
Explanation:
Adware is software that displays advertisements, whether or not the user has consented. Adware is
software that automatically downloads
and display advertisements in the Web browser without user permission. When a user visits a site or
downloads software, sometimes a
hidden adware software is also downloaded to display advertisement automatically. This can be
quite irritating to user. Some adware can also
be spyware.
Answer B is incorrect. Spyware is a program that takes partial control over a user’s computer
without user’s permission. Spyware
programs can collect various types of personal information, such as Internet surfing habits, and Web
sites that the user has visited. Spyware
programs can also interfere with the control of a user’s computer, such as installing additional
software, redirecting Web browser activities,
accessing Web sites blindly, etc.
Answer D is incorrect. A honeypot is a term in computer terminology used for a trap that is set to
detect, deflect, or in some manner
counteract attempts at unauthorized use of information systems. Generally it consists of a
computer, data, or a network site that appears to
be part of a network, but is actually isolated, and monitored, and which seems to contain
information or a resource of value to attackers.
Answer A is incorrect. Trojan horse is a malicious software program code that masquerades itself as
a normal program. When a Trojan
horse program is run, its hidden code runs to destroy or scramble data on the hard disk. An example
of a Trojan horse is a program that
masquerades as a computer logon to retrieve user names and password information. The developer
of a Trojan horse can use this
information later to gain unauthorized access to computers. Trojan horses are normally spread by email attachments. Unlike viruses, Trojan
horses do not replicate themselves but only destroy information on hard disks.
