Required if you use the Norton AntiVirus 2003 or older versions.
ccApp.exe is the common hosting application that is used for both Norton AntiVirus (NAV) and Norton Internet Security (NIS).
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.
It loads for each user that logs on to Windows 2000/XP. For Windows 98/Me, this program only loads once.
So basically you do not have an updated, fully functioning anti-virus program. Since one of these processes appears to be associated with an older version of Norton, you may want to consider updating.
