Malicious worms can be exploited to destroy the user system and launch DDoS attack against computer networks. The authors proposed a method of forming secure P2P network using benign worms against malicious worms. The corresponding benign worm with a hitlist is generated to clean the malicious worm and patch peers in the P2P network which is based on the largest distance list. The benign worm propagates along the histlist. The spread of the benign worm is also a distributed patching process. The patch can be disseminated more quickly and the network congestion is much less than centralized patching scheme in P2P networks.
