In one particular aspect of the present disclosure, the control module 160 may include in advance a list of priorities, which in turn includes information regarding the level of priority of each method of checking. Moreover, the control module 160 performs a periodic review of the priorities of the antivirus check methods. For example, the Internet speed has decreased, and consequently the priority of the check method by request to the security service 195 decreases.
The control module 160 then determines which component (170 or 180) needs to perform the selected methods of the antivirus check. The choice of the components is based on at least the following conditions: the presence of a functional in the component responsible for performing the corresponding antivirus check method, the workloads of the VMs 150 or the SVM 140 including the components of the antivirus system 200 that are performing the corresponding methods of the antivirus check, and the resource intensities of the selected methods. In one particular aspect, the presence of access to an external network 190 may be yet another condition.
Since the functional responsible for performing a particular method of antivirus check was formulated immediately when installing the components (the agents 170 and the antivirus module 180) on the corresponding virtual machines, the control module 160 has full information on the capabilities of the components.
The control module 160 obtains information as to the workload of the VMs 150 and, consequently, the workload of the components 170 and 180 from the hypervisor 130, since the hypervisor 130 controls the computing resources and the interconnection of the VMs 150 with each other.
