PROBLEM TO BE SOLVED: To prevent, secondary disaster due to the virus infection, considering the influence on the whole system when a virtual storage area is infected with a virus. SOLUTION: A NAS (network attached storage) device 10 stops, when virus infection of a file transmitted from a client computer is detected, operation of a file management module using a directory group which may store a virus-infected file among file management modules controlled by each user OS. According to this, since only the file management module using a directory group likely to be infected with a virus can be stopped even if one directory group is virus-infected among a plurality of directory groups, secondary disaster due to virus infection on other logic volumes can be prevented and operational loss of the computer system can be suppressed.
