专利汇可以提供System for checking destruction of execution format file专利检索，专利查询，专利分析的服务。并且PURPOSE:To easily specify a suspected file and to prevent a computer system from being infected by computer virus by totally comprehensively executing a check while paying attention onto the character of infection caused by the computer virus. CONSTITUTION:A file existence checking mechanism 6 investigates whether the file name of an execution format file taken out from a file system 1 by an execution format file take-out mechanism 5 exists in data read out from a file checking data base 2 or not. A file length checking mechanism 7 investigates whether the real file length of the execution format file is coincident with the file length of the same file registered to the file checking data base 2 or not, and a file checksome checking mechanism 8 investigates whether the checksome of a byte string is coincident or not. Then, alarming messages are respectively outputted to a picture display device 9. Thus, the suspected file is specified by easily checking the infection of the computer virus and the computer system is prevented form being infected.，下面是System for checking destruction of execution format file专利的具体信息内容。
