My computer is pegging at 99% CPU usage from Norton 360. I've gone through the threads about this issue, and it seems that it was supposed to have been fixed in the most recent hotfixes - not so much. It looks like that over the past week, my computer has not been only been at about 80% or less CPU usage from Norton for only about half a day - the other 5 days it was on was all over 90%.
I've uninstalled Norton and reinstalled using the provided tool, and made sure to install all updates and reboot my computer.
Generally, after a reboot, the computer seems to behave normally, however, when the computer has been idle for any period of time, it just starts getting pounded by N360, and never lets up.
I'd talk to a rep, but my wait time is estimated to be over an hour.
