Computer viruses are still one of the main security threats in the Internet. For virus outbreaks prevention, we need to fully understand their spreading dynamics and how it can be affected. Many viruses include inter-human contacts in their spreading and observations have shown that these inter-contact times are often heavy-tail distributed. The contacts between humans form a logical network over which viruses spread and the topology of this network plays important role in the spreading dynamics. The rapidity of spreading also depends on the location of initially infected nodes in the network. By selectively infecting the most influential nodes in the network the virus outbreak can grow faster. We analyze this effect for networks with different topologies, by using nodes selection based on several node centrality measures and the k-medoids graph clustering algorithm.
