Norton 360 running two processes

Why would there be two versions of 360 running on my computer?  ... and how do I get it to stop?  When I look at the task manager it shows both, but when I access the control panel and try to delete one of the two, there is only one copy of it.  I tried to "end task" on one of them and nothing happened.  Ok, maybe I'm a bit of a task manager freak, but there is something that just drives me nuts about unnecessary stuff running on my computer.  Anyhow, its just super weird and any help would be greatly appreciated.  Thanks in advance :)
