PROBLEM TO BE SOLVED: To provide a logical method and system for defending and removing computer virus by dimensionally converting outside electronic information from an electronic information system into another information system different from electronic information. SOLUTION: Outside electronic information is fetched by a dummy receiver 4 having a function for temporarily receiving outside information, and this received information is dimensionally converted into another information system different from electronic information in a virus wall 7 so that a computer virus can be removed. Afterwards, this information is restored into electronic information. Thus, a main computer 12 can receive the outside electronic information as clean electronic information after the computer virus is removed, and perform original information processing work. |
