Adware
Definition
Adware is software that generates revenue for its developer by automatically generating online advertisements in the user interface of the software or on a screen presented to the user during the installation process. While some adware is harmless, it can also be a form of spyware that tracks user behavior without consent.
Why It Matters
Adware can be extremely annoying, degrading the user experience with unwanted pop-ups and ads. More malicious forms can compromise user privacy by tracking browsing habits and other personal information.
Contextual Example
A user installs a "free" browser toolbar, which then starts injecting extra banner ads and pop-ups onto every website they visit. This is adware.
Common Misunderstandings
- Adware is often bundled with free software downloads.
- While not as directly damaging as ransomware, it can be a gateway to other types of malware and a significant privacy risk.
