From Symantec: "ccApp.exe is the common hosting application that is used for both NAV and NIS. It loads for each user that logs on to Windows 2000/XP. For Windows 98/Me, the application only loads once. ccApp is responsible for calling the different program features of NAV and NIS. For example, in NAV, if Auto-Protect and Email Scanning are enabled, then ccApp makes sure that those programs are running. If ccApp is disabled, then, Auto-Protect and Email Scanning will not run."
ccApp.exe comes with Norton Anti-virus 2003 and Norton Internet Security 2003. Located in "C:\Program Files\Common Files\Symantec Shared\".
