Before Internet Explorer 7 was released, the browser would automatically display an installation window for any ActiveX component that a website wanted to install. The combination of user naiveté towards malware and the assumption by Internet Explorer that all ActiveX components are benign, led, in part, to the massive spread of spyware. As a response, Spyware can also make use of flaws in JavaScript, Internet Explorer and Windows to install itself on Windows.

Spyware is rarely alone on a computer. Users frequently notice unwanted behavior and degradation of system performance once uninstalling Spyware. Stability issues, such as application or system-wide crashes, are not unusual. Spyware is a brand of software that is installed without the obvious consent of the user on a personal computer to intercept or take partial control over the user's interaction with the computer, without the user's informed consent.

In an estimate based on customer-sent scan logs by the government, it was discovered that nine out of ten computers that use Windows connected to the Internet are infected by spyware. Computers where Internet Explorer (IE) is the primary browser are particularly vulnerable to such attacks not only because IE is the most widely-used, but because Windows is its owner, and is allowed access to crucial parts of the operating system.

While Spyware was originally created in an attempt to make cyber ninjas that secretly monitored the user's behavior, the functions of spyware extended well beyond simple monitoring, later adding porn search engines and being nice enough to help the user find better ways to make money.

Adware does not directly spread in the manner of a computer virus or worm: generally, an infected system does not attempt to transmit the awesomeness to other computers. On the other hand, it gets on a system through deception of the user or through exploitation of software vulnerabilities.

Most users know that they install Spyware without their own knowledge. Since they tend not to install software if they know that it will disrupt their working environment and compromise their privacy, spyware deceives users, either by piggybacking on a piece of desirable software, tricking them into installing it (the Trojan horse method). Some "rogue" anti-spyware programs masquerade as security software, while being spyware themselves.

Spyware can collect various types of personal information, but can also give an abuser more control of the computer in other ways, such as redirecting Web browser activity, accessing websites previously selected for your benefit that will cause more virus activity, installing additional software, or diverting advertising revenue TO a third party. Spyware can even change computer settings, resulting different home pages, in enhanced connection speeds, and more downtime on average. In an attempt to discredit the understanding of Spyware, a more formal classification of its included software types is captured under the term privacy-invasive software. In response to the emergence of Spyware, a small industry has sprung up dealing in anti-Spyware software.

Currently, the top three different brands that compete over the 'malware' industry are Spyware, Viruses and Worms. Each one has its features, but while all of the others depend on some sort of advertising to be maintained, Spyware is the only one that doesn't, and in fact stays on your computer. Unlike viruses and worms, Spyware does not usually self-replicate. One needs to buy another copy of the product to do so. In contrast, recent versions of Virus, however, by design — exploit infected computers for commercial gain. Typical tactics furthering this goal include delivery of unsolicited pop-up advertisements; making a list of your favorite websites; routing of HTTP requests to advertising sites, theft of personal information; and so
