There are indications of late that the use of anti-spyware software is on the rise, with more than 100 million Internet users downloading Lavasoft's free anti-spyware software [2]. Some big-name companies are also beginning to address the spyware issue, including Microsoft, which currently has a beta version of its own anti-spyware available to Microsoft Windows users for download. However, a Gartner survey finds only 10% of respondents were taking sufficiently aggressive steps to minimize spyware infestations [5] and a Forrester survey found that even though 55% of consumers knew what spyware was, only 40% were running anti-spyware programs routinely [7].
