A floating blue box appears that displays changing iconic images. A large T in a blue box, a running person, an E like the internet explorer icon. And the letters DCR in a blue and white box. It ends with a check. And then appears again at random intervals. The cursor goes under it. I have also noticed a person icon has appeared in google chrome that asks me to access my settings to put them on all my devices. I cannot close it. Does anyone know what is causing this?
