ccapp.exe is the email client component for SAV/SEP
as this is included in the startup , i think its referring to your previous install of sav,this happens if the install is corrupted.
when you install sep on top of sav, it get installed in Symantec antivirus folder
if its a fresh install;it wil be installed under symantec endpoint protection folder
remove ccapp.exe; uninstall sep and reinstall it again ;this should fix the issue.
