Used to get that all the time on my phone, but only when I went to "The Chive." Phone would buzz and couldn't back out our kill it. Finally discovered if I pressed the number in a square in the upper right corner (tab number?) it would reduce the text to a smaller square and show an "x" that would kill it. Don't go to Chive on phone anymore cause I don't have an anti-virus installed but I do go on my home computer. About every other time I go to the Chive my anti-virus has to kill a couple of things.
