Abstract

Malicious codes may be prevented from performing malicious actions in a computer that does not have a virtual machine by simulating presence of the virtual machine. When a computer program performs an action in the computer, the action may be intercepted to determine if the computer program is malicious code probing the computer for presence of the virtual machine. A response to the action may be in accordance with convention of the virtual machine when the action is deemed to be for purposes of detecting the virtual machine. Otherwise, the action may be allowed to proceed.
