Ads and pop-ups that will not go away

Get rid of a frightening warning safely, and take away the permission that let it appear in the first place.

A red page appears saying viruses have been found, giving a telephone number, and telling you not to turn the computer off. Every part of that is the trap.

It is a web page. It is printed on the screen the same way a newspaper article is, and it knows nothing whatever about your computer. It cannot see inside it. The pictures of scanning progress are a drawing.

Your computer does warn you sometimes, and the difference is not subtle once you have seen both.
