My laptop is fine but when i occasionally use my phone it's awful- within a few seconds I get a loud buzz and a message telling me I've won an iphone or a fake popup that' i've been infected by something; so I have to exit AB. There may be a way to stop it but i don't know how.
I Do Not have a smart phone but nevertheless understand that installing and using as your Browser 'Opera Mini' your phone can be freed of all 'pop-ups' and adverts.
