Explanation:

Spyware is used to collect personal information stored in the computer and send it to a third party
without the permission of the user.
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 option C is incorrect. 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 hidden adware software is also downloaded to display advertisement
automatically. This can be quite irritating to user. Some adware can also be spyware.
Answer option A is incorrect. Grayware refers to applications or files that are not classified as viruses
or trojan horse programs, but can still negatively affect the performance of the computers on your
network and introduce significant security risks to your organization. Often grayware performs a
variety of undesired actions such as irritating users with pop-up windows, tracking user habits and
unnecessarily exposing computer vulnerabilities to attack.
Answer option D is incorrect. A firewall is a program or hardware device that prevents data packets
from coming in or going out to a specified network or computer. It is used to separate an internal
network from the Internet. A firewall restricts inbound and outbound access, and can analyze all the

traffic between a network and the Internet. It checks the protocol through which the packet is being
delivered, and the port number to which it is being sent.
