Update Virus Database on S6
Searching the name of that "virus" returns only results for NQ Security, who are essentially a nobody company accused of creating spyware to trick people into paying for their useless security app.  In my opinion, this is a complete scam.

You should check in Settings &rarr; Security (or Safety &amp; Privacy) under Device Administrators and remove any apps that you don't want controlling your device (if present), and then remove anything suspicious under Settings &rarr; Applications.  Specifically, remove anything from NQ or any anti-malware software you don't recognize.
