STRONGLY ISOLATED MALWARE SCANNING USING SECURE VIRTUAL CONTAINERS

摘要

Described systems and methods allow protecting a host system, such as a computer or smartphone, from malware. In some embodiments, an anti-malware application installs a hypervisor, which displaces an operating system executing on the host system to a guest virtual machine (VM). The hypervisor further creates a set of virtual containers (VC), by setting up a memory domain for each VC, isolated from the memory domain of the guest, VM, The hypervisor then maps a memory image of a malware scanner to each VC. When a target object is selected for scanning, the anti-malware application launches the malware scanner. Upon intercepting the launch, the hypervisor switches the memory context of the malware scanner to the memory domain of a selected VC, for the duration of the scan. Thus, malware scanning is performed within an isolated environment.
