What is the main purpose of adware?

The main purpose of adware is to automatically display or download advertisements. This type of software is designed to generate revenue for software developers by displaying ads to users, often in the form of pop-ups or banners. While adware can sometimes track user behavior and preferences to tailor the advertisements shown, its primary function is centered around delivering advertising content.

In this context, it’s important to note that other types of malicious software have different primary purposes. For instance, remote access tools are typically used by hackers for unauthorized entry into systems, while some malware focuses on data collection or self-replication to spread across networks. However, adware specifically targets advertising, making the correct answer focused on its role in delivering advertisements directly to users.
