Vista - Security Between Host and Virtual PC

Hello all!

As background: I have a 64 bit Vista Ultimate rig running Virtual PC 2007
(SP1), with a Vista 32 bit VPC set with Shared Networking (NAT) and with Undo
disk turned on (i.e. you can dispose of changes after each session). The host
machine runs Windows Live OneCare (firewall, AV/AS, etc.), and I run as an
Administrator on this machine, but with UAC turned on.

The virtual PC is running NOD32 2.7, and I run as a Standard User on this
instance. I fully patch Windows when updates come out, and update NOD32
before going on the internet with this virtual PC.

How great is the risk of the host Vista OS becoming infected with a virus
from the virtual PC in such a configuration? I know its theoretically
possible, but how realistic?

Thanks in advance!

The risk is basically the same as you would have with 2 physical
computers configured in the same way.
IMHO, it's not very likely to happen.

In article <0qvca4ts1kb4de1f9d9iqqm5qrj1kft8ms@xxxxxx>,
boberglund@xxxxxx says...In a way it does :-) This thread is about security of operating systems
and Goosbee tells us he downloaded (and ran?) a program he does not know
what it does or what it is for. In general a good way to get your system
infected.

My reading is that Gosbee is a VPC2007 newbie and does not even know
where to start. Not uncommon really.
But it should be addressed by a *new* thread "How can I use VPC2007?"
or similar, or better yet by reading the FAQ and the numerous posts
here before attaching an unrelated question to a specific thread.

He will not have any security problems because he does not even know
how to create a guest and install an operating system in that yet...
