Android adware: risks, techniques and removal advice

📱 Android adware can range from benign ad‑supported apps to intrusive PUAs that harvest data, perform click fraud, or hide to prevent removal. Detections rose by 160% in H1 2025, and sophisticated campaigns such as Kaleidoscope — which uses identical “evil twin” apps across official and third‑party stores — accounted for a substantial share of incidents. To reduce risk, only install apps from reputable developers and the Google Play Store, keep software updated, enable PUA detection in mobile security tools, and if infected disconnect, reboot to Safe Mode and remove suspicious apps or run a trusted scanner.
