摘要
An antivirus (AV) application specifies a fault handler code image, a fault handler manifest, a memory location of the AV application, and an AV application manifest. A loader verifies the fault handler code image and the fault handler manifest, creates a first security domain having a first security level, copies the fault handler code image to memory associated with the first security domain, and initiates execution of the fault handler. The loader requests the locking of memory pages in the guest OS that are reserved for the AV application. The fault handler locks the executable code image of the AV application loaded into guest OS memory by setting traps on selected code segments in guest OS memory.
