The method includes the following steps: (a) receiving mail or a messenger transferred from all kinds of external servers or terminals in a receiver′s terminal; (b) checking a compressed file attached to the received mail or messenger in a filtering system in the receiver′s terminal and extracting a compressed file list; (c) verifying integrity or extracting and checking a hash value; (d) comparing information stored in a result database (DB) and information of the compressed file to be checked and checking the same; and (e) storing a check result if there is the check result and performing a check in the filtering system if there is no check result.
