Abstract: The invention discloses a network virus detecting method based on network data streams and a device thereof in a TCP/IP network. The method comprises the steps of classifying network virus according to the types of host files, fragmenting the characteristics of the network virus according to different description types, recombining special numbers of network data packets into network data streams, matching the network virus characteristics after being classified and segmented with the network data streams, detecting implicit network virus in the network data streams and scanning format characteristics of webpage files in the matching process so as to detect embedded network virus. In the invention, twice matching can be carried out for the network data streams and the network virus characteristics to detect the embedded network virus, thereby the network virus spread in the TCP/IP network can be effectively and accurately detected, network users can be prevented from being attacked bynetwork virus spread by a network, and a safe network environment is provided for the network users.
