Do you suspect it was probably a rogue malicious ad on an otherwise legitimate website?Here's one that flashed up whilst I was doing something yesterday, using W10. Started with a quick flash of a woman in a compromising position, which got me suspicious, followed by the screenshot below. Surprised me as I was looking at stuff on another question raised by someone on the forum and hadn't gone to any suspicious sites or clicked on any links. This froze the Edge browser and couldn't do anything else in it. But being aware I closed it down with Ctrl - Alt- Delete and using Task Manager. Have passed the site link on to those who can do something about it.
