As the title says, i had left my laptop on hibernate during the night and when i opened it back up the next morning, my wallpaper suddenly changed into a picture of an anime character? There was even a shortcut to the characters Wikipedia and the picture that was used for the wallpaper on my home screen. Am i being hacked? I live with nobody that would pull this type of prank on me. Nobody touched my laptop since last night, what is happening???
