A scanning manager scans the file systems of virtual machines running on a base computer. In order to scan a virtual machine, the scanning manager identifies the file on the base machine that represents the virtual machine, freezes the virtual machine, and creates a snapshot thereof. The scanning manager restarts the frozen machine, and starts the snapshot. The files of the snapshot are mapped at a virtual machine level, and the resulting file mapping information is used to scan the files of the virtual machine at a base machine level. The scanning can comprise scanning for malicious code, such as virus signatures. The scanning manager can scan one, multiple or all virtual machine(s) running on the base computer, in conjunction with a full or partial scan of the base computer, or independently.
