POTENTIALY UNWANTED PROGRAMS

Potentially unwanted programs, unlike malware programs, are not intended solely to inflict damage.However they can be used to breach the computer's security.

Potentially unwanted programs include adware, pornware and other potentially unwanted programs.

ADWARE

Adware programs involve display of advertising information to the user.They display ad banners in other program's interface and redirect search queries to advertising websites.
Some adware programs collect and redirect to their developer marketing information about the user, for example, which sites he or she visits or which search requests he or she performs (unlike Trojan spies, these programs transfer this information with the user's permission).

PORNWARE

Usually, users install such programs themselves in order to search for or download pornographic information.

Intruders also can install these programs on the user's computer in order to display ads of commercial pornographic sites and services to the user without his or her permission.

To be installed, they use vulnerabilities of the operating system or web browser, Trojan downloaders and Trojan droppers. There are three types of pornographic nature distinguished based on their functions.
