QUESTION: What is spyware?
ANSWER: Spyware is software installed on your computer without your consent. Spyware can monitor your computer behavior, sending that information back to advertisers, along with diverting you from a desired website to another. One way to avoid spyware is not to download (or add) any programs onto your computer without being sure of the source and that you need the software offered.
You can install anti-spyware software on your computer. This is a topic best dealt with by asking friends or relatives in the know or a computer professional who can help install anti-spyware software and/or help remove any spyware that was found on your computer.
