If the data is the program data of the predetermined type, step S403 is executed: the data is isolated so that the data cannot be launched or called.
In another embodiment of the present invention, the data isolation may specifically include: and storing the received data of the preset type in a preset storage area, and setting the preset storage area to be inaccessible to the non-specified process. Wherein the designated process can be customized according to the operation of a user. Optionally, the default non-system process is not accessible.
In another embodiment of the present invention, the data isolation may further include: converting the received program data of the preset type into a data file of a preset format, for example: the file is converted into an encrypted file in a compressed format and is converted into a graphic data file. Converting the data can call a third-party format conversion program to convert, or directly modify the suffix name of the data file, such as: exe is modified to. jpg.
Optionally, the received program data of the preset type may also be converted into a data file of a preset format and stored in a preset storage area, and the preset storage area is set to be inaccessible to the unspecified process.
If the data is not the program data of the preset type, step S404 is executed: the data is processed in accordance with conventional processing logic. For example: and storing the data in a default storage directory, and executing corresponding operation.

The description information of the program data may include, but is not limited to: type information, reception time, risk level, identification information, and the like of the program data. Wherein, the danger level can be determined according to the type of the program data and the authority of the operation. It will be appreciated that the risk level of the bootstrap data is higher than the risk level of the executable program data. Program data that has the right to read and modify data in memory at runtime is at a higher risk level than program data that does not have the right to read and modify data in memory.
Alternatively, the description information may be output in a list manner in the screen.
