Spyware is a general term used to describe software that modifies certain behaviors, such as advertising, personal data collection, or computer configuration, usually without the right consent.
Spyware is often associated with software (eg adware) or software that contains personal or sensitive information.
This does not mean that any software that gives ads or tracks online activities is bad. For example, you can subscribe to a free music service, but you'll "pay" for the service by accepting targeted ads. If you understand the terms and accept them, you have decided that it is fair trade. You may undertake to keep track of your online activities to determine which ads to show.

However, these programs make it very difficult to restore the settings as originally shown.
The most important thing is whether you understand or not (or the person using the computer) to understand what the software agreed to install the software on your computer.

Spyware can collect email addresses, even passwords and credit card numbers.
Apart from ethics and privacy, SpyWare steals the use of computer memory resources and gaining bandwidth as it sends information back to the home base of the spy device through the user's Internet connection. Because SpyWare uses memory and system resources, background-based applications can lead to system failures or general systemic disease

License agreements accompanying software downloads sometimes alert the user to install SpyWare with the requested software, but the license agreements are not always fully legible because SpyWare is often legible, legible legitimate part of the installation exclusion.
Examples of SpyWare
How common SpyWare programs show the diversity of behaviors encountered in such attacks. It should be noted that, like computer viruses, researchers provide SpyWare programs that their creators can not use. Programs can not be grouped into "families" with "shared code", but on frequent behaviors or "follow-up" of apparent financial or business relationships. For example, many of the SpyWare programs distributed by Claria are commonly referred to as "Gatorns".

o The Internet Optimizer (also known as DyFuCa) redirects Internet Explorer error pages to ads. When users are tracking a bad URL or typing an incorrect URL, they see an ad page. Because password-protected sites (HTTP-based authentication) use the same mechanism as HTTP errors, the Internet Optimizer does not allow the user to access the password-protected sites.
