Abstract

A remote machine uses a process control unit to monitor a process for a Web browser program. When the process for the Web browser program starts to operate, an operating time therefor starts to be measured. When the operating time reaches a predetermined time, the process for the Web browser program is forcefully terminated. After that, unless the remote machine 2 is rebooted, that is, unless a RAM is cleared, the process for the Web browser program is forcefully terminated immediately after its start.
