My wife has a Samsung Galaxy S5 running Android 4.4.2
Just in the last week she has been getting popup messages when browsing that say "Warning your android system is expired" with an OK button.
She pressed the OK button and it links her to an App called "360 Security - Antivirus Free"
I have not downloaded the app in fear it could be a virus of sorts.
However, I'm not too sure if the phone is already infected with some sort of virus because this message keeps coming up, and has only just started doing it in the past week.
Today, I got exactly the same message on my Galaxy Note II running 4.4.2 for the first time...
Any Suggestions on how I can get rid of this?
Should I be running an AV App on the phones?
