Definition

Spyware and Adware are both examples of Malware. Malware is software designed to infiltrate and possibly harm a computer system, without the owner's consent or knowledge. Viruses and Trojan Horses are also considered examples of Malware. The difference with Spyware and Adware is that they are designed for-profit. They can monitor a user's web browsing, redirect users to an affiliate's website and display unwanted ads. Spyware is designed to intercept or take partial control of a computer's operation without the informed consent of its owner or legitimate user. Adware is designed to display ads, with or without the computer operator's consent. Adware is different from advertising-supported software, in that advertising-supported software display ads as an alternate to charging fees for shareware and does not try to deceive the user (and lets the user know upfront that they will see the ads). Bonzai (Bonzi) Buddy, Gator software, Bargain Buddy, CoolWebSearch and 180 Solutions are all examples of Spyware.

Ways Spyware and Adware are Spread

Spyware and Adware do not spread in the same manner as computer viruses; they are installed either by exploiting a browser security breach (which is a very good reason to keep your patches up to date) or piggybacking along with the install of another software program (like a Trojan Horse). They are covertly installed during the installation of other software you want, such as music or video file sharing programs, or many freeware products.

Signs of a Spyware and Adware Infestation

  • Computer seems sluggish or crashes - Spyware and Adware are using resources to run. They can cause significant CPU activity, disk usage and network traffic that can interfere with legitimate use of these resources. It can take much longer to start your computer.
  • Links to programs stop working.
  • You see pop-up advertisements all the time (even when not on the Internet)
  • Settings get changed and they can't be changed back. For example, your internet home page gets changed or your browser search engine is different.
  • Your web browser has additional components that you don't remember installing. This includes things like a new toolbar or icons.
