If the resident software is authenticated, the processor loads the available software only if the available software is also authenticated.

The disk includes software to cause the computer to execute the anti-virus software.

In preferred embodiments the caching software plugs into the server software.

Finally the input software outputs the input content to an application software.

The supplemental software is divided into action software (52) which acts solely on the basic service, and supplemental software (59) which acts on the remaining supplemental software.

On execution the client software enables communication with server software.

The disk includes software to cause the computer to execute the anti-virus software.

The former executes application software transparently to that software.

The overall network device driver comprises a kernel-space device driver (10) and user-space device driver functionality (20).

The digitally signed software is provided to the software developer.

The software execution means merges the software and the inspection program when the second software reception means has received the inspection program.

The software comprises library software and player.

The system then modifies the software to render it readable and identifies the software with the electronic system by storing an identifier of the system with the software.

If the resident software is not authenticated, the processor loads the available software onto the computing device.

The method includes: dividing the PC side management software into the basic function software and the additional function software, and storing the basic function software in the memory of the mobile terminal.
