Hello, ever since I took images from the internet, icons for "desktop," "folder," and "thumbs" have appeared in all my documents (images, videos, music), and many images (album covers among others) are cluttering my folders. When I delete these icons, my PC tells me that my computer or one of my programs might not function properly anymore, and when I restart my computer, all those files I had deleted are back again.
Is it a virus? A mistake on my part, or just an option to disable?
Thank you for your help.
