gray box inside every picture and document on desktop
i connected to a public wifi network today and right away 3 cmd promt boxes appeared saying system 32 and disappeared. afterwards, all of the pictures and documents on my desktop were highlighted. and now they have this gray box on the inside bottom left hand corner with a line going across diagonally. what just happened and what are these gray boxes? i ran a scan with norton 360 and malwarebytes and i don't seem to have anything. i included a pic of the gray boxes. what do these gray boxes mean and why are they there?
