Adware
Adware is software that displays advertising, sometimes in intrusive or deceptive ways, and may also collect browsing or device information.
In simple terms
Some advertising software is disclosed and accepted; unwanted adware changes browser behavior or shows excessive ads without meaningful consent.
Technical explanation
Adware may arrive bundled with another installer, add browser extensions, redirect searches, or collect usage data. Whether it is classified as malware or potentially unwanted software depends on its behavior and consent.
Advertising software ranges from unwanted but disclosed behavior to programs that change browser settings, track activity, or expose users to deceptive ads. Source and permissions determine the risk.
Examples in practice
After installing a free utility, a browser begins opening sponsored pages and sending searches through an unfamiliar extension.
A bundled installer changes the browser's search provider and injects ads into shopping pages. The user removes the extension and the team blocks that installer in its software catalog.
Why it matters
Investigating adware also reveals how unwanted software entered the device and what information it may have collected.
