Today I opened my mailbox in my new Samsung galaxy J7 and this screen appeared:

WARNING Your Samsung galaxy j7's browser is still infected with a serious virus! Continue with instructions to fix the phone. Do not close this window.**Exit at your own risk.

When I pressed OK, it took me to UPDATE BROWSER, and on pressing 'back' the phone started vibrating crazily! As the alert was from GOOGLE, I decided to go with it and pressed 'UPDATE BROWSER', it took me to a new page sitex.dmtracker001.com, but luckily error 400 appeared and it didn't connect.

The warning and vibration didn't go away until I restarted the phone, but it appeared again after some time and nothing I do makes it go away.

I don't know what to do, please help me.

    You most likely visited some shady website and/or installed a very bad app. Go through the list of recently installed apps and remove the one(s) that seem like they would cause such things (like wallpaper apps that also require all permissions).

First - as you are probably aware now. You NEVER click on a link from an unknown source. I repeat - NEVER. Next time, just close the window without clicking on any links Second - if you can't figure out which malware app was installed , you need to consider doing a factory reset on your phone to eliminate all threats. A factory reset will erase the data (Text messages, photos, videos, settings, everything on your phone will be removed in the reset process.).... I would do it anyway just to be certain that I got it all. You may be able to backup any pictures or video. The easy way to reset is to go to Settings -> backup and recovery -> Reset Device -> Erase everything.


Pretty much have been cleared by comment and answer. But in this case a single of clearing cookies from your browser will help you to get rid from that pop up.

Other wise you can do factory reset. I have been passed through such situation.
