Spyware And Spycheckers By Jackson Summers At Isnare.com Ezine Articles

What is Spyware?

Spyware refers to an extensive class of malicious software designed to seize control of a user’s computer without permission or informed consent, in order to benefit a third party such as an advertisement agency. Spyware can collect different kinds of user information and track what types of websites are visited, launch popup advertisements etc. In the process, spyware can drain the computer's resources, adversely affect Internet connection speed, and even forcibly redirect web browsers. Spyware may be classified on the basis of

1. shared program code
2. busness connections
3. common behaviors

Spyware, Adware and Virus:

Spyware is intended to track, report, and re-sell user’s activity and information without consent, and can be almost impossible to completely uninstall without assistance. Adware, on the other hand, is usually installed with the user’s consent and comes with an uninstaller. Spyware also differs from virus or worms because they are not specifically designed to disrupt or devastate the functioning of a computer, they hardly ever replicate themselves, and are created for the sole purpose of commercial gain. Spyware can

1. launch pop-up advertisements
2. steal personal information such as credit card numbers
3. monitor web surfing activity
4. and reroute HTTP requests to advertising domains

In more serious cases, when a computer is infected with a large number of different types of spyware, reinstalling the operating system may be the only available option.

Well-known Spyware Programs:

Some of the most notorious spyware applications and packages that have been identified include

1. CoolWebSearch – which directs traffic to advertisements on websites such as http://coolwebsearch.com
2. Internet Optimizer – which redirects Internet Explorer error pages to advertising
3. 180 Solutions – which transfers information to advertisers about the surfing habit of a user
4. HuntBar (or WinTools): which is an example of how spyware programs can install more spyware

Spycheckers:

In order to battle the spyware threat that has invaded the computing world, concerned programmers have come up with several anti-spyware software programs and spycheckers. These applications are designed to eradicate or block the malicious spyware programs, by cleaning an infected system and prevent new infestations with real-time protection. Spycheckers have now become one of the most downloaded programs on the internet.
