Spyware And Spycheckers
Author: Jackson Summers

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.


Some of the popular, most effective anti-spyware tools and
spycheckers include
