Very active CPU on VMWare Virtual Server

Very active CPU on VMWare Virtual Server

I have recently moved my ServiceDesk and OpManager installation to a Virtual Server on a VMWare ESX server. I have noticed that the CPU is very active on this Virtual Machine. The only things installed are McAfee Virus Scan, ServiceDesk, OpManager, SolarWinds TFTP. It is a Windows 2003 OS with SP1 and all the hotfixes. Please let me know how I can troubleshoot the issue of the very active CPU.
