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

Best practices for resolving COH32 issues

A clean and tidy computer is the key requirement for avoiding problems with COH32. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the COH32.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
