Adware and Spyware

Adware is 'freeware', whereby ads are embedded in the program. These ads will show up whenever user opens the program. Most adware authors provide the free version with ads and a registered version whereby the ads are disabled. As such, the users have the choice, either to use the freeware with ads served or
purchase the registered version.

Spyware, as the name suggest is the software installed on user’s computer which is constantly sending user information to the mother website.

Spyware, however, is published as 'freeware' or as 'adware', but the fact that an analysis and tracking program (the 'spyware' agent, which reports user’s activities to the advertising providers' web site for storage and analysis) is also installed on user’s system when a user install this so-called 'freeware', and this is usually not mentioned. Even though the name may indicate so, spyware is not an illegal type of software. But what the adware and spyware providers do with the collected information and what they're going to 'feed' the user with, is beyond his control. And in some cases it all happens without the user’s consent.
