Spyware is software that aims to gather information about a person or organisation without their knowledge that may send much information to another entity without consumer's consent or that asserts control over a device without the consumer's knowledge.
Some of the earliest spyware did little more than report to the authors each time the program was used. It was intended as a marketing aid or to monitor usage for licensing purposes. That still goes on, but a lot of spyware nowadays is designed to steal confidential information - user names and password for banking sites, email accounts, social networking sites and online games. You may never know you have malicious spyware on your computer, as it tends to work quitely in the background and the overt functionality and quality of the program may be very appealing.
How spyware enters your computer:
- Advertisement on Internet
- Fake Anti Spyware
- Shareware and freeware
- Hackers, etc.
Effect of spyware on your computer:

To sum up, spyware may give negative effects to internet users, especially if we use internet at random ways. We can prevent it by installing Anti Spyware and so on, of course we have to be careful when we open shareware and freeware.
