Spyware and How to Protect your Computer From It

Spyware was in headlines for the first time in 1999 when a freeware game called " Elf Bowling" circulated with spying software along with it. Since then spywares are creating a havoc in the computer world. Some of the downloadable software comes with a licensing agreement that a spyware program will be installed along with the requested software. But most of us do not go through the agreement properly.

Spyware exists as independent executable programs. These malicious software have the ability to monitor keystrokes, change the default home page on the Web browser, read cookies, scan files on the hard drive, install other spyware programs and even spy other applications, such as chat programs or word processors. The spywares continuously relay this information back to the person who is spying. He will either use it for advertising/marketing purposes or sell the information to another party.
