Adware is a type of software that is designed to display advertisements on a user’s computer, typically advertisement-supported software. Adware is generally installed without a user’s knowledge and often runs hidden in the background of their computer.
Adware is used to collect user data, which is then used to display targeted advertisements to the user. It is also used to generate revenue for its publishers, as well as other parties. The data collected can be used for various purposes such as tracking the user’s activities on the Internet, targeting ads to them, and creating a profile of their computer usage habits. Adware can come in different forms, including search toolbars, pop-ups, in-text ads, browser hijackers, and malicious websites.
Adware can be installed in the form of bundled downloads, such as free applications or games, or deceptive downloads, such as fake antivirus software. It is also possible to install adware by clicking on malicious links or authorizing the installation of a browser extension.
Adware can cause security risks, such as the risk of exposing personal information, distract the user from legitimate tasks, slow down their computer, and interfere with their web browsing activities. Users can protect themselves from adware by installing software to detect and block adware, avoiding deceptive downloads, and closely examining company privacy policies before signing up for services or using applications.
