| Explanation & Hint:
Adware is a type of software that is installed on a user’s device, typically without their full knowledge, which displays unwanted advertising and collects information about the user’s browsing habits. Adware can be intrusive and can degrade the user experience by displaying ads or redirecting browser searches to advertising websites. It’s often bundled with free software or downloads and can be considered a form of potentially unwanted program (PUP). The primary purpose of adware is to generate revenue for its developers by showing advertisements to the user. Some adware tracks user behavior to target ads more effectively. While not always malicious in intent, adware can affect system performance and can sometimes lead to security vulnerabilities. |
