Part of Symantec Shared-Various Symantec applications use the shared virus definition folder \VirusDefs (usually located at C: \Program Files\Common Files\Symantec Shared\VirusDefs). These applications create temporary folders and files under this shared folder.

My COH32.exe used up 100% CPU when it runs. Fixed it by uninstalling Norton and re-installing again. For uninstall used Norton Removal Tool.

It's part of Symantec EndPoint Protection V 11 (could also be part of earlier version). As it's digitally signed and from Symantec, I have no problem with it even though it's CPU utilization occassionally spikes.
As part of Norton AntiVirus it is probably important
This is a process that runs along beside Symantec Antivirus on most programs, It is the proactive scan so will scan files and changed done on the computer in real time. This is normally fine but if you are having 100% cpu issues like one of my customers were then simpally uninstall and reinstall Symantec product, There seams to be a memory and CPU leak
