Also included in this lesson is information about deleting temporary files, some links to SRT downloads, and a link to a site that compares SRTs, so that you can choose the one that best meets your computer needs.

Note: Some refer to spying files as Trojans, Dialers, Browser hijackers, Adware, or Malware, etc. The term Spyware will be used for this lesson.

What is Spyware? (Also called trojans, dialers, browser hijackers, trojans, and adware)
Spyware collects information about your browsing activity or obtains personal information such as credit card numbers, logins, etc. Spyware files can be downloaded on your computer and you may have no idea that they are there. If you have downloaded information such as music files from the internet, or have downloaded programs, chances are you have spyware lurking on your computer causing adverse effects.

How Spyware affects your computer
Spyware is often the cause of those annoying pop-up ads, and can cause you to be flooded with spam. Spyware can also cause your computer to run unusually slow. In addition, when spyware invades your computer, you may notice that strange software loads when you start your computer. You may also notice unusual searchbars and toolbars, or that you cannot change your default homepage settings. Overall, spyware is not detrimental to your computer, but detrimental to you since it invades your privacy.

Note: some programs that you download will not run without spyware installed.

How Spyware invades your privacy
Spyware is an invasion of your privacy since it can record passwords, logins, and even bank account and credit card information. Also, companies that place spyware on your computer know what your interests are since they track the sites that you visit, and then can sell your personal information to outside parties without your knowledge or consent. Also, when spyware has invaded your computer, it will be more susceptible to hackers. Identity theft is one of the major invasions of privacy in which spyware has contributed.

Antivirus software will not protect your computer from Spyware. Although some antivirus software companies are taking steps to address spyware, most antivirus programs provide little or no protection against spyware. Spyware is legal because it is oftentimes installed on your computer with your consent (purposely hidden) when you accept Software or End User License Agreements. Consequently, remember to carefully read the License Agreements of software that you install on your computer. Many antivirus software companies hesitate to label programs as spyware (or malware, adware, etc.) for fear of being sued.
