Abstract: The traditional security services mostly put virus killing entities inside the users’ operating systems,which causes huge resource expenditure and waste,and the security software itself is in the unsafe environment,thus being easily destroyed by malicious programs,so it is difficult to ensure the integrity of the security service.Therefore,this paper proposes a new virus killing mechanism with no proxy.The service entity is placed outside the protected operating system,and no plug-in or proxy program is installed in the protected system.Based on virtualization platform,online and offline virus killing are realized by using virtualization technology,and no plug-ins are required to be inserted into the system,which ensures the integrity of the service.Experimental results show that,the proposed offline virus killing security service has better user transparency,can effectively detect whether the current process of the system is malicious code or not,and successfully terminates malicious programs.
