Adware

Adware is a type of software that is commonly found on the internet. It is generally unwanted and intrusive, and typically generates revenue for its creator by displaying advertisements or collecting marketing data. While some adware is benign and non-intrusive, other types of adware can be used to infect computers with adware-carrying malware or spyware.

Adware is often installed in software packages together with a legitimate software program. While the user is typically informed of the adware before installation, the information presented may be vague or incomplete. It has been argued that this practice is a form of malware. In most cases, users have to accept the presence of adware in order to get the features offered by the software.

Adware can be used to display advertisements on webpages, search results, or within program windows. These advertisements may take the form of pop ups, banners, floating texts, and video ads. Some adware programs are known to slow down computers, or to cause browser crashes or errors.

Some adware can track users’ online activities in order to deliver targeted advertisements. This is done through tracking technologies such as cookies, web beacons, and history sniffers. Adware can also collect information such as email addresses, web browsing history, and search queries. This information is then shared with third-party networks that use it to create data profiles of users.

Adware is typically difficult to remove from computers. In some cases, users need to manually delete adware files and registry entries in order to completely remove it. In addition, some types of adware have been known to be difficult to detect and disable, even with an anti-virus software.

Adware can be dangerous for computer users, especially those who do not have protective anti-malware and anti-virus programs installed. As such, it is important for all users to take precautions to protect their computers against the threat of unwanted adware.
