when I start Hyper-V manager & start a VM, the McAfee On Access Scanner Service jumps to 100% cpu on one of the cores. I am running Windows 8 with McAfee agent 220.127.116.118. If I stop & then start the McAfee agent it sometimes seems to settle down, other times it goes back to 100% cpu again. If I stop the Hyper-V console the service still runs at 100%.
I have tried adding mmc.exe to the On Access exclusions but still seem to be getting the problem.
