Mike,
Has it always been like that? Have you tried a reboot on this server and then check the process? It might have happened because you would have tried restarting services using Backup Exec service manager. A reboot should fix it. You may also kill it from the task manager, without affecting Backup Exec. Click on tools-> services in BE console, after you have killed it to observe the CPU usage through task manager, once it is restarted.
Please mark it a solution, if this is useful.
Thanks
