Browser Extension is adware that may insert an unwanted add-on, plug-in or browser extension on the Web browsers such as Internet Explorer, Mozilla Firefox, and Google Chrome. Once installed on the computer system, Browser Extension may generate and display intrusive pop-up advertisements, messages and banners carrying various online saving coupons, discount deals, sales and other offers. Browser Extension may seem to be a useful tool to online shoppers. However, in truth, Browser Extension may be considered to be a potentially unwanted program if it installs itself on the PC without the computer user's approval. Browser Extension may circulate and enter the PC as an additional program bundled with freeware that computer users can download from unreliable download websites. Browser Extension may keep track of the PC user's surfing habits and gather browsing details that may later be used with the purpose to deliver targeted advertisements. Browser Extension may be created with the aim to generate advertising revenue from clicks on ads and messages.
