What is the purpose of adware?

Adware primarily serves the function of delivering advertisements automatically to users while they browse the internet or use certain software applications. This type of software is typically designed to display ads in various forms, such as pop-ups, banners, or within the context of other content. By targeting specific audiences based on their browsing habits or preferences, adware aims to generate revenue for its developers, often by partnering with advertising networks.

While adware can collect user information, its main functionality revolves around facilitating the ad delivery process rather than just the act of collecting data. Adware does not inherently aim to disrupt normal computer functions or replicate itself, which are characteristics associated more with malware or other types of malicious software. Thus, the central aspect of adware is its role as a tool for automatic advertisement distribution, making it clear why this answer is the most accurate choice among the options presented.
