What is adware? Why your phone shows unwanted ads

Adware is software that pushes advertising onto your phone, often outside the app that installed it.

By Psylinks Security ยท Updated November 2026

Signs of adware

  • Full-screen ads appear when you are not using any app.
  • Your browser homepage or search engine changes on its own.
  • New icons or notifications you did not ask for.
  • Your phone slows down or the battery drains faster.

Why it matters

Some adware is just annoying. Some collects browsing and device data, and some opens the door to more serious malware through malicious ad links.

How to remove it

  1. Open Settings, then Apps and sort by recently installed.
  2. Uninstall anything you do not recognise.
  3. In Chrome, clear site notifications you do not want.
  4. Run a scan with a trusted security app.

Ad-free by design

Frequently asked questions

Are free apps with ads adware?

Not necessarily. Normal ad-supported apps show ads inside the app only. Adware shows ads elsewhere or hides itself.

Can adware steal my data?

Some can collect device and browsing data. That is one reason to remove it.
