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.
