High CPU usage when using Symantec Endpoint is likely to be caused by the bug in the software that was identified and resolved as part of Release Update 6. If the problem occurs shortly after start-up of your system, it may be due to a start-up scan that is configured to run.


To resolve the problem, update your software to Release Update 6 or later. If you have a start-up scan enabled, this can be disabled, which will reduce CPU usage when you first boot up your computer.
