I have secure anywhere webroot installed on my phone. I t says I iam protected and no threats are detected but I am getting a message continually popping up on my home screen telling me to clean my phone, asking have I been hacked, etc and pornagraphic messages are being sent.  I clear them from my home and they just come back. They are not connected to my email or text. They continuously pop up. How can I stop them? I do not want to click on or go to the website.
