The security of Ad hoc networks has received more and more attention recently with the widely use of Ad hoc in many areas. Virus spreading over the network can cause significant damage and the loss of network security. On the other hand, the anti-virus process also plays an important part affecting the virus spreading. Considering the characteristic of dynamic topology of Ad hoc networks, the virus spreading is different from wired networks. In this paper we present four virus spreading models and analyze the effect of node mobility, multi-hop and anti-virus function on virus spreading. The simulation result indicates that multi- hop and mobility can accelerate virus spreading. However, increasing transmission range will reduce the effect of mobility and enhance the effect of multi- hop. The anti-virus function can decelerate the virus spreading and reduce the infection rate. With the increase of transmission range, the anti-virus function can keep the infection rate at a lower degree which will prevent the virus from spreading.
