The software for Symantec Endpoint Protection includes a process simply known as SONAR Component. Although there is little information available about the file itself, it appears to be related to a feature of the software described as “proactive threat protection.” The file seems to do scheduled scans every fifteen minutes or so, a task which is said to consume a considerable amount of CPU resources; thereby slowing down CPU speed. You can configure file settings to prevent the file from running several times in an hour, and instead run it on a schedule that you prefer. This is a core component of the AV software, which is why uninstalling it is not recommended. Disabling it is likewise not recommended. Default folder of the file is C:\Program Files, and its general path is C:\Program File\Common Files\Symantec Shared\coh32.exe. The file has different versions, and file size depends on the version. File sizes however, do not differ all that much; just between a.197 KB and 1.198 KB.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. coh32.exe. is used by SONAR Component, If you shut down coh32.exe, it will likely start again at a later time either after you restart your computer or after an application start.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.
