The invention relates to an apparatus for preventing infection by malicious code, comprising: a database in which files installed in an agent system, DNA values for each portion of the files, and index information for indicating whether each file is normal or malicious are stored; a calculation unit which calculates a DNA value for a portion of a file for which an execution is requested in the agent system; and a file inspection unit which searches the database to extract, in a group, files having the DNA value calculated by the calculation unit, inspects whether an object file is normal or malicious on the basis of the index information on the files extracted in a group, and allows the execution of the object file or makes a request for the calculation of DNA values of other portions which selectively include one portion of the object file.
본 발명의 실시예들은 본체와 수납체의 편중된 한쪽에 단일 부품으로 처짐을 방지하면서 슬라이딩 되도록 설치됨으로써 제작 비용이 축소되고 슬라이딩 효율이 향상되며, 본체에 고정되는 부분이 일체로 구비됨으로써 제작 비용이 더욱 축소될 수 있다.patents-wipo patents-wipo
