On my mom's laptop, she had a html icon on the desktop. She deleted it, but it left like a "blank" icon. I can't get rid of this thing. I can drag it around on the desktop, but can't delete it. I've tried renaming it, but nothing. I've tried deleting it in safe mode, but still nothing. I've tried cmd line deleting it. I don't know what else to do. I've scanned with many malware scanners, but nothing was found. Does anyone else have suggestions? It's W10 64b.
