What is Spyware
Spyware can be defined as any software that attempts to collect data of some specific type from your computer and sends it to the creators of the spyware. This illegal data collection and data transmission occurs without your consent and very often, without your knowledge.
Spyware can enter your computer from virtually anywhere when you are connected to the internet. The most common source are the downloads. There are several websites that offer free downloads of games, screensavers, wallpapers, music, videos, computer tuning software, and much more. When you download any of these, there are some chances that you are also downloading a spyware attached to the item being downloaded.
Though most websites take care that downloads from their links are free of any malicious software attachments, there are methods through which spyware can be placed in your computer through these downloads. As soon as the spyware enters your system, it starts collecting and sending your private data to the programmer of the spyware until some antispyware detects and destroys the spyware. You can get detailed information on spyware at the Microsoft Knowledgebase.
