Apple Users

This is what swatted it for me at the time. Hopefully matches what you see in current version of OS. Basically go completely offline, close every open Safari window, "kill" Safari, and clear all the history and websites.

I would also say turn off JavaScript as an extra layer, and install an ad blocker. Some people have good luck using a different browser. Malware doesn't make it easy.

Ok, instructions:

* Turn on airplane mode
* Open Safari
* Tap the overlapped squares in the lower right
* Close every page by tapping the "x" in the left upper corner of the page
* When there are no pages left press HOME (On an iPhone X series swipe up from the bottom edge) and wait a couple of seconds
* Double-press HOME (On an iPhone X series swipe up from the bottom edge and pause)
* Swipe up on the safari image to kill it (On an iPhone X series touch and hold Safari, then swipe up)
* Press HOME again (On
* an iPhone X series swipe up from the bottom edge)
* Go to Settings/Safari and tap "Clear History and Website data"
* Turn off Airplane mode
