Why do I keep seeing ads on my phone? How do I make it stop?

I frequently see ads on my phone. My tech-savvy friend configured that it is happening because of few settings, such as app permissions, browser tracking or could be a malware. How can I make it stop?

CUJO, a newly announced smart Internet security device

Apologies if this is an inapprotiate post, but we just announced our CUJO device and we are looking to reach an audience that loves technology as much as you do. CUJO is a smart device that guards all of your connected home devices from hacks. It's simple to start with no installation necessary. CUJO blocks malware, viruses, phishing attempts, and hacks. You get an app that alerts you anytime your devices are in danger. Best of all, you can get it for only $49 when you back their Indiegogo campaign.

How does CUJO work? CUJO was engineered to start in seconds. It connects to your wireless router with one cable. Your connected devices will still stream directly to the router, so your wireless range is not affected. CUJO will inspect all of the connections within your network as well as data leaving and entering your home. CUJO learns from your device behavior so that it can detect anomalies as soon as they occur.

Thank you!
