The ccapp.exe process is a core component of Norton Antivirus. It runs in the background continuously checking your system for viruses and trojans. It also checks any inbound email for similar threats. If the process is stopped Norton antivirus will not be able to protect your computer. It's very possible that your system may be infected if the above medthod has not worked.
What I would like you to do first is download HijackThis from http://www.spywarein.../HijackThis.exe
and create a log.
Save HijackThis to a folder other than your Desktop or the Temp folder.
Save it in a Permanent folder.
Click My Computer, then C:\
In the menu bar, File->New->Folder.
That will create a folder named New Folder, which you can rename to "HJT" or "HijackThis".
Now you have C:\HJT\ folder. Put your HijackThis.exe there, and double click to run it.
Run the program, and press "Do a system scan and save a logfile".
After HJT runs, the log will show (notepad will open).
After notepad opens, click edit – select all then edit –copy .
Then paste that log onto this topic.
Do not delete or modify anything yet.
