Dick, you will find that it takes a seperate license to run a Norton product in a VM since the "hardware" of a virtual machine is different than the host system.  (most of it is virtualized).

Subash, I think you will find that the behavior for a windows VPC is different than a Mac.

Files downloaded into a Virtual PC do not "pass through" the host system so they can't be scanned or intercepted by a AV installed on the host.   I can download and run the Eicar test virus in a VM and NIS on the host system doesn't bloack it in any way.

I'm not familar with how a Mac does virulization but it seems like it must be sending the files from the host into the VM.

As for NIS scanning the virtual had drive, it can't do that either.

Norton products do not support .vhd files as "containers" like it does with archives like zips and rars.

Although it really should support them, it's a very common format.

You can right click and scan the vhd files but it only scans tham as 1 file, Norton is not able to scan the files inside the container.

In order to do a manual scan of the contents of a VHD, the easiest way if your using windows 7 is to use disk management to mount the vhd as a hard drive and then scan it like you would a normal drive.

You also could "share" the VHD wile it is in use and scan it like a network drive but it should be considered bad practice to share the root of another system over the network.
