What is Adware as the type of malware in the computer system?

Adware is a type of malware that displays unwanted advertisements on a user's computer system. It is often bundled with free software or downloaded unknowingly by the user. Adware can track a user's browsing habits and display targeted advertisements based on the collected data. It can also redirect the user's browser to specific websites or change the browser's homepage. While adware is generally considered less harmful than other types of malware, it can still slow down the computer, consume system resources, and invade user privacy.
