High-efficiency online batch antivirus system and method of virtual machine

Abstract

The invention relates to a high-efficiency online batch antivirus system and a high-efficiency online batch antivirus method of a virtual machine. Three privately-owned tables are maintained for each virtual machine creatively, information of programs which are safe, doubtable and required to be terminated after judgment is stored in each privately-owned table; when the safety of the program is required to be judged, the tables are looked up; if the matched program exists, the same treatment as that to the matched program is carried out, so that rescanning to the same program in the same virtual machine is avoided; a common table is maintained for all virtual machines, the program information and scanning information, scanned by antivirus software, are stored in the common table, the common table is looked up when judgment needs to be carried out on the safety of the program and the program does not need to be in the private meter of the current virtual machine, and the treatment is performed according to the scanning result of the matched program, so that rescanning to the same scanned program in different virtual machines is avoided; the antivirus software is called for the programs which are failed to look up in the privately-owned tables and the common table for scanning to achieve the purpose of high-efficiency online batch antivirus.

Description

[0001] technical field [0002] The invention relates to the technical field of virus detection and killing, in particular to an online efficient batch virus killing system and a virus killing method for virtual machines. Background technique [0003] With the rapid development of cloud computing, virtualization technology, one of its cores, is increasingly used in various fields. From small PCs to the deployment of large-scale enterprise server virtual environments, the application of virtual machines is becoming more and more extensive. Utilizing virtualization technology can not only improve the utilization rate of software and hardware resources of the whole system, fully save costs for enterprises, but also bring great convenience to management. [0004] Virtualization refers to virtualizing a computer into multiple logical computers through virtualization technology. The essence of virtualization technology is to enable multiple virtual machines to use a single physi...

AI Technical Summary

Problems solved by technology

[0009] Existing security protection methods need to consume a lot of resources, resulting in reduced performance of virtual machines, contrary to the goal of virtualization

Moreover, the security protection for multiple virtual machines on the same physical machine is independent of each other. Repeated scanning and killing of the same process appearing on the same virtual machine or physical machine takes up time and resources.
