Intranet Journal has a great tutorial on Identification and Removal of Spyware. This is a basic, but really good, explanation of the whole spyware mess; I especially like the tips the articles gives on recognizing the major types of spyware. Although programs like SpyBot Search and Destroy and AdAware are terrific for ridding your computer of spyware, it’s not enough to use this software — learn why your computer is becoming infected in the first place.
