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 option C 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 option B 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 option 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 e-mail attachments. Unlike viruses, Trojan horses do not replicate themselves but only destroy information on hard disks.
