    • A system of preventing virus from intruding into a network, comprising a detecting unit for virus detection of the traffic passing through the network, and a controlling unit being connected between the terminal and the network; the controlling unit is used for controlling the terminal to access to the network and determining whether the terminal accesses to the network according to the detection result sent by the detecting unit. A method of preventing virus from intruding into a network comprises: real-time virus detection of the traffic passing through the network; if the activity feature of virus spread or the attack spread activity is detected, then locating the terminal in which the activity feature of virus spread or the attack spread activity and reporting the information of the terminal; refusing the terminal to access to the network according to the information of the terminal. According to present invention, all the traffics of the terminal being infected with virus are limited and the connection between the terminal and the network is terminated, therefore, the large-scale spread and propagation of virus in the network can be prevented, and the security of network operation is improved.
