At certain times, I'm getting a pop-up window in Chrome or the built-in Internet application. I always restart my phone when I get messages like this. These messages will occur either when going directly to a website by typing the address or from the Google screen. I've got Kaspersky Internet Security installed and recently did a factory reset of my phone. These websites are places like politico.com and dailymotion.com.
What can I do about these messages?
Had this happen a lot of times, also fixed others phones. People get freaked out by it. Just ignore it. If it wont go away just clear the data from Chrome to resolve it.
