ABSTRACT:
An E-mail program according to the present invention can protect an existing file from the infection by computer virus, when a user receives an attached file sent from a transmitter through a communication network. In the present invention, an execution power for accessing another file of the attached file is set to a particular level. The E-mail program always checks the reference/overwrite to another file in which the attached file of the received mail intends to execute. When not-permitted process occurs in the attached file as a result of checking, the E-mail program informs it to a user. Further, the attached file, in which not-permitted process is found, is cancelled so that it is possible to avoid an accidental mistake, i.e., “accidental opening of the attached file without checking the infection of the computer virus”, on the user side.
