Parasiteware is technology (including, but not restricted to, browser helper objects (BHOs), browser plug-ins, toolbars and Pop-ups) that knowingly or unknowingly hinder or block another affiliate's ability to generate revenue by changing, intercepting or redirecting an affiliate link. Parasiteware may be installed knowingly or unknowingly by the end user. Parasiteware can alter Web browser functions and/or install a third-party application that works through the user's altered browser. Many Web sites depend on affiliate links to pay for hosting or provide an ancillary source of revenue. Affiliate links are links to products, usually related, for which the Web site receives a percentage of any sale that results from a potential customer following the link. When Parasiteware blocks link-following and substitutes its own affiliate link, it is in effect stealing the commission from the Web site that recommended the product originally. Parasiteware can infect a user's computer via direct installation, piggybacking, or security holes. Direct installation occurs when a user installs a program that claims to provide enhancements, such as a toolbar, but is actually Parasiteware. Piggybacking occurs when Parasiteware attaches itself to a free software program that a user installs. Security holes are known flaws in Internet Explorer that Parasiteware exploits to enter a computer while browsing. |
