Somehow you turned it on.
A few days ago, I noticed a small, grey icon appear at the top of my screen. I have never seen anything even similar to this before and it seems very strange. It is under anything I do on my PC, even screenshotting so I have no way of showing what it looks like. If I am playing a game in fullscreen it still shows up above, watching YouTube fullscreen Etc.
I am normally quite techy and find a solution within a few minutes to most of my problems but I couldn't find anything that could be even slightly similar to this. It just popped up randomly as far as I am aware, nobody else uses this computer and I didn't download anything to my knowledge. Any advice on this problem would be much appreciated.
The icon is grey in colour, with a white border of a circle with arrows at the top and bottom, next to a gap. Overnight a red line appeared through the circle, in the same fashion as if it was a no smoking sign.
