What is this, is it a threat, is it safe to delete it? Folder on disk called "DataCardGKU," when opened shows a cogwheel icon named "datacardu". Bottom line reads "1 item, (3.8 mb) 2.7 mb free space" Root permissions outside read, but it is an executable file. I could only find ONE reference on the web, a UNIX page how to remove it. I don't want to wipe this thing off if it is part of my OS (Linpus Lite)
