Aiming at mobile communication of internet of vehicles（IoV）

to prevent and cure worm

control extra network resource cost

a novel IoV hybrid anti-worm based on passive response is constructed.After receiving a message including worm

this anti-worm takes a passive response of propagating itself in the process of relay broadcasting this message

and can not only avoid extra network resource cost caused by sending probe packet from active anti-worm

but also better contain the worm propagation.Research results provide theoretical basis and a new solution for design of real-time prevention and cure strategy and counterworking worm destructive propagates.
