How does adware work and what risks does it pose to PC users?

Adware, or advertising-supported software, is a category of potentially unwanted programs that force users to view excessive advertisements while using their computer. Unlike outright malware, adware is often installed by the user themselves along with free software, as it is distributed through honest partnership models or hidden behind checkbox options during installation.

The main manifestations of adware include the sudden opening of pop-up windows, modification of browser search engines, injection of banner ads into all visited websites, and redirection to dubious advertising landing pages. In addition to being annoying, such software significantly slows down the browser and operating system, and may also collect marketing data about the user's habits without their explicit consent.
