4. History and development
The first recorded use of the term spyware occurred on October 16,1995 in a
Usenet post that poked fun at Microsoft’s business model. However, in early
2000 the founder of Zone Labs, Gregor Freund, used the term in a press
release for the Zone Alarm Personal Firewall. Since then, "spyware" has taken
on its present sense. According to a 2005 study by AOL and the National
Cyber-Security Alliance, 61 percent of surveyed users' computers had some
form of spyware. 92 percent of surveyed users with spyware reported that
they did not know of its presence, and 91 percent reported that they had not
given permission for the installation of the spyware.] As , spyware has become
one of the preeminent security threats to computer systems running Microsoft
Windows operating systems
