<P>PROBLEM TO BE SOLVED: To prevent other control devices from being infected with viruses. <P>SOLUTION: A USB memory 10 changes a file name of an automatic execution file to a file name which is not recognizable as the automatic execution file by a control device 20 when the automatic execution file is stored in an information unit 131. Namely, the USB memory 10 prevents the control device 20 from reading content of the automatic execution file through communication when the control device 20 becomes communicable with the USB memory 10. In this way, it is possible to prevent that the control device 20 acquires specific content data (virus data, for instance) from the USB memory 10 and automatically executes it when the control device 20 becomes communicable with the USB memory 10. Thus the USB memory 10 is able to prevent the control device 20 from being infected with a virus through the USB memory 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
