Private enquiry?

Private enquiry

Hello,
Each time I switch on my Samsung Galaxy S5 I get this warning;
"SYSTEM WARNING" Your battery system has been severely damaged. Your SIM
Card, Data, Applications and Battery will be damaged if you do not repair it now"
I am sure is a malware or virus and will not click on anything but what is causing it and how do I remove it?
Many thanks
Tony

Welcome to Android Central! Is it a popup message? Does it only appear when you're actively using the browser, or does it appear even on the homescreen?
