___Spyware is installed in your computer

by unsrupulous salesmen who track who you visit on the web in an effort to sell you whatever they have for sale. Spyware can fill your computer with so much trash it will crash. I use Ad Aware SE Personal Edition to identify and remove Spyware.

___Viruses are inserted into your computer
by people who want to destroy your computer. I use Norton AntiVirus to protect my computer.
