I installed Windows Virtual PC within Windows 7 Pro 64 bit. I think it is amazing since this is my first foray into virtual machines. When the Virtual PC is open and running it does not have any AV or malware programs installed. I searched around in the forums because I think it has been discussed before but I could not find it. Do I need to purchase a separate license of Prevx to run with in the Virtual PC or is there someway to use the installed license the I have on my PC?
