After installing Microsoft office 2013, two files popped up on my desktop. One is a blank file with no name, while the other is a folder called "Microsoft OneNote NameSpace Extension For Desktop Search" When I right click on either of them, the only options are to cut, create a shortcut or to delete. I tried deleting both of them, and they appeared to be gone, but when I refreshed the desktop, there they were again. I don't know if this is some kind of malware or if it's a bug with office, but either way, if you know what's going on and how to get rid of it, please tell me!
