Here is a recent scareware attempt (used to scare you into action) on my own phone, I was watching a video of a structure fire when my phone started to vibrate and the first image appeared. Tried to close it using my back button on my phone not the browser and found the other image below the video. Don’t fall for this, it is a scam! Just like the fire service: Stop, Drop the phone, and Roll your eyes. Don’t let scams win. (Ps drop your phone on soft surfaces so as not to damage the device)
