Summary:A USB memory (2) is provided with an MBR storage unit (261) and a distributed processing unit (221). The MBR storage unit (261) stores an MBR which is a program which has been set so as to be prioritized in startup by the BIOS of a terminal (1), for reading a loader and mapping thereof upon a boot memory area (120) of the terminal (1), said MBR causing a stack area (1203) to be positioned to overlap the higher-order bits of the vector 2 with respect to an interrupt vector table (1202) that has been set in the boot memory area (120). A distributed processing unit (221), preceding boot of the MBR, partitions the loader into a pre-set number of units and creates mapping information for when loading each partitioned loader into the boot memory area. As a result, operation of malware is suppressed by an external boot.
