Spyware Definitions List


The list of definitions of adware and spyware is very long. But the definitions listed below are the most common. This glossary contains basic information about spyware so that you know what these malicious programs are and what they can do for your computer.


Advertising software components are usually installed with a shareware or free program that you download. The adware developer creates pop-ups generating ad revenue for these ads. Most adware components are actually installed with the consent of the user. This happens because most people never read the End User License Agreement that came with the software.


Spyware is most often installed with free software or shared software, much like adware. Spyware collects and transmits sensitive and personal information about your online behavior to an unknown person. The data is collected without you even knowing it has happened. At the moment you discover it, the damage is done and the pirate is gone for a long time.

Browser hijacker

Browser hijackers are innocently installed as useful browser toolbars. They can change your browser settings and change your default home page to point to a site generating revenue for the hijacker.

Trojan programs

Trojans programs sneak into your system and run without you realizing that it looked like spyware. Programmers use these programs for a large number of malicious uses and none of them would be approved. The good thing is that Trojan programs do not duplicate themselves.

Tracking cookies

Tracking cookies are files containing small amounts of data such as passwords and parameters. Tracking cookies can bring you an advantage, especially if you visit the same websites again. But in the wrong hands, cookies are used to track your Internet behavior without your knowledge and consent and provide marketers with private information about you.

Key loggers

Keyloggers are programs that run in the background and silently record all your keystrokes. Once the keystrokes have been recorded, the hacker uses a remote keystroke program to retrieve the data later. The hacker can get your passwords, credit card numbers and any personal information on your computer.


The definition of malware is malware or software that will harm your computer. Computer viruses, worms and Trojans are all considered malware, but several other types of programs can also be included under the term.

Password cracker

A password cracker is simply a program used to decrypt a password or password file. Security administrators use password crackers for legitimate use by using them to improve system security. But the dangers when a hacker gets a program like this are unimaginable.

There are many other definitions of spyware, including scumware, annoyanceware, parasites, and the list continues to lengthen each day.
