#1 Fake Virus Warning #2 Profit!
Ah yes, the age old scam of extorting money and/or user data through fear.
Very much like this app developer that is affiliated with Avast .
#From the Google Play Store reviews of the app:
"DO NOT GET THIS YOU HAVE TO PAY FOR IT BUT IF YOU GET IT THEN GET RID OF IT YOU WILL GET MESSAGE AFTER MESSAGE TELLING YOU THAT YOU HAVE A VIRUS AND REALLY YOU DON'T SINCE LAST NIGHT FROM 11:30 PM I HAVE GOTTEN OVER 100 MESSAGES FROM THIS DUMB APP:"
