I entered a web site from my LG G2 and i took a warning on screen in web browser. (not chrome, other official web browser called “internet”) It says: “Warning. G2 has infected. Install an antivirus from Google Play” and there was OK button on warning and when i clicked OK it sent me to 360 Total Securty page on Google Play. And also on browser, another web pages opened. (ali.express was one of them) How can it know my phone is G2? is it possible a web page can know what is my phone model? was it a virus? has my phone infected? Please help thanks..
