Abstract: Based on the primary-secondary response mechanism and learning，a novel mechanism of anti-pollution for files is presented.This mechanism has the abilities of learning，memory，and evolution，and can learn and produce the antibodies automatically during the period of identifying the polluted files.When the polluted files appear again，the system can identify them rapidly and stably，combined with the conventional algorithm.After the polluted file is identified，a new antibody is produced and stored.Repeating the above process，the system’s learning ability and response rate become stronger and stronger.Consequently，the performance of the system can be improved.Simulation results demonstrate that the system performance is stable.
