I have Malwarebytes on my Alcatel android phone. For the past 2 months it says Malware found. The malware is listed as Android/Adware.TCTWeather, System Application, Weather. When I click on Remove selected, I get a message that says Disable system app, Weather is a system app and cannot be uninstalled. Please disable this app manually and we will automatically add it to whitelist. How do I disable manually and what is a whitelist?
