Method and device for processing application programs

The invention discloses a method and device for processing application programs. The method comprises the step of obtaining catalogues where all progresses in a log exist by reading the active defense log, the step of obtaining catalogues where uninstall programs corresponding to the application programs installed in a terminal device exist, the step of determining the application programs corresponding to the progresses in the log by comparing the catalogues where the progresses in the log exist with the catalogues where the uninstall programs exist, the step of carrying out statistics and obtaining the using situation information, including the number of the times that the application programs are used and/or the time when the application programs are used, of the application programs by a user according to the application programs corresponding to the progresses in the log, the step of determining the target application programs which are not usually used by the user according to the using situation information, and the step of uninstalling the target application programs, or displaying a prompt message about the target application programs to the user. By means of the method and device, the effect on the system performance from the application programs which are not usually used can be reduced.
