I'm running it on a stand alone system, with no internet connection. Did you install it and get an alert or something? Could it be a false warning?
Edit - Last night I installed it on system 2 of 3 in my house. System 1 (my sons) is stand alone with no internet, firewall or anti-virus. Last night after installing the program on system #2 (my laptop) and starting the program, my firewall did popup asking to connect to the internet. I DENIED access and saved that setting in my firewall. I've ran a virus check and find nothing. 
How sure are you that it has a virus? Have you found info on the internet I've missed?
