Abstract
The present invention prevents a computer, which is infected by an unauthorized program such as a virus or spyware when the computer is brought out, from being connected with a secure network such as an intracompany LAN. When a user terminal is started, a connection with the intracompany LAN is attempted. Then, a network connection is temporarily stopped and an environment is compared with the one where the user terminal operated at a previous time. When there is no difference between both of the environments, the connection with the intracompany LAN is restored. However, when it is determined that the user terminal is connected with a network other than the intracompany LAN when the user terminal was operated at a previous time, an inspection for a virus or the like is executed by a USB memory where the latest anti-virus software is stored. After it is confirmed that the user terminal is safe, the connection with the intracompany LAN is restored.
