How does Spyware Work?

Spyware programs are annoying little buggers! They can cause the user a lot of problems too. Spyware can monitor keystrokes, scan files on your hard drive, read cookies, open applications and without the user’s knowledge, it can transfe private information over the Internet to a third party. One of the worst things about it is that pop-up advertisements will just ‘appear’ on your computer without the browser having to be open.
