The invention discloses a processing method for application files and a mobile communication terminal. Firstly a plurality of function privileges of a first application file with privacy protection are determined, which are used for obtaining privileges of various privacy files on the mobile communication terminal. Then a plurality of function privileges of a second application file are obtained when the second application file has an operation, and the function privileges of the second application file are compared with the function privileges of the first application file, then whether a compare result obtained after comparison meets a preset condition is judged, the fact that the operation of the second application file possibly has a risk for revealing the function privileges is indicated if the compare result meets the preset condition, the second application file is forbidden to execute the operation, the use of the second application file is avoided, and further effective protection on a privacy function on the mobile communication terminal is realized.
