A couple of weeks ago a new folder showed up in My Computer with no name. The type says "System Folder". When I leftclick on it nothing happens and if I right-click on to look at the Properties, the only options are "Cut", "Create Shortcut" and "Delete". I tried to run an Norton anti-virus scan on it but it doesn't show up in Norton's "Scan Folders" list of folders. The only cause I can think of is that I may have disconnected a USB drive without having used the "Safely Remove Hardware" procedure. Any idea as to what this is and if I should just delete it?
