[TenTec] dedicated laptop for ham programs, rig control

[denton]

Hi all...
I am getting ready to set up a laptop for ham radio software and rig control 
only.
I do not want to run any kind of antivirus progam on the dedicated 
laptop..and do not want it connected to the internet, for other than program 
upgrades and registration.
The pc has vista installed...but can set it up with windoz 7...
Is there any problem running mixw on the dedicated laptop while it is 
registered on the main pc?
I am using rigexpert standard as the interface, N4PY rig control software 
for the Orion and Omni VII.
