With his latest investigation to find what was taking a large portion of CPU time, David Passell gives us his findings here. "I located it thanks to the Activity Report. It appears to be related to the iAntiVirus freebee. The actual process running is iAVD and it "belongs to root".

David concludes, "When I clicked on it and Quit Processor I received a request to enter my administrator password. After I did that iavd quit and the processor usage went back to a few percent. I think, if possible, I will delete iAntivirus.

Any other suggestions?"
