Claim:
A mobile communications terminal, comprising: receiving means for receiving a plurality of sets of pattern data that are transmitted from a server device; extraction means for extracting specified pattern data from said plurality of sets of pattern data received by said receiving means on the basis of terminal information relating to said mobile communications terminal, wherein the specified pattern data extracted by the extraction means defines first pattern data, and the received pattern data that was not extracted by the extracting means defines second pattern data; and storing means for storing said first pattern data, without storing said second pattern data, wherein said terminal information relates to the memory capacity of said storing means, said pattern data is used for the detection of computer viruses and is received by said receiving means together with information indicating a degree of danger of said computer viruses and a size of said pattern data, and said extraction means extracts said specified pattern data from said plurality of sets of pattern data in order from the highest degree of danger within a range in which the size of said pattern data does not exceed said memory capacity of said storing means.
