“…The basic reproduction number in [11] is determined by the rate at which files are downloaded (i.e., ), the probability of successfully downloading files (i.e., ), the rate at which files are executed (i.e., ), the probability of successfully executing files (i.e., ), the rate at which infected files are deleted (i.e., ), the probability of successfully deleting infected files (i.e., ), and the number of uninfected files. If online and offline are not considered, the basic reproduction number in [12] is determined by , , , , and (i.e., recovery rate) and the number of uninfected files. The parameters , , , and are constants related to the occurrence of infection, which can cause the susceptible nodes to become the infected ones, while the parameters , and are constants related to the occurrence of recovery, which can cause the infected nodes to become the susceptible ones.…”
