Abstract
Provided are a terminal and a file distributor determining method of the terminal. According to embodiments of the present invention, files pre-executed in the terminal and distributor information of the files are cached. When a new file is generated in the terminal, the new file and the cached files are compared, and distributor information of the new file is extracted so as to prevent the spread of a malicious code in advance.

A terminal, comprising:
- a cache unit storing an identification value associated with at least one file pre-executed in the terminal and distributor information associated with the at least one file;
- a detecting unit to detect whether a new file is generated in the terminal;
- an identification value generating unit to generate an identification value of the new file when the generation of the new file is detected;
- and
- an extracting unit to extract, from the cache unit, distributor information of a file having an identification value identical to the identification value of the new file.
