Online social network services have attracted more and more users in recent years So the security of social networks becomes a critical problem In this paper we propose a virus propagation model based on the application network of Facebook which is the most popular among these social network service providers We also study the virus propagation with an email virus model and compare the behaviors of a virus spreading on Facebook with the original email network It is found that Facebook provides the same chance for a virus spreading while it gives a platform for application developers And a virus will spread faster in the Facebook network if users of Facebook spend more time on it (C) 2010 Elsevier B V All rights reserved
