Hello and welcome to BC!
ccApp is probably from your Norton software, but it all depends on where it is located on your computer. It is possible that it is malicious. And if you were to say that you never had Norton on your machine, I would tend to lean towards the malicious. But from what you have said so far it is certainly plausable and even probable that it is from Norton. The only way to know for sure, like I said earlier, is to know that file's location on your computer, and whether you have more than one file of that same name on your computer.
You can turn off unneeded programs by going to : Start > Run >
type msconfig > OK > Startup tab
Here you will see a list of programs that start automatically when you boot your computer. But most average computer users find this list cryptic and confusing at best. Another method you can use is downloading a running a little free program called Startup Inspector
. This lists the programs found in msconfig > Startup in more laymen's terms, and even rates the programs for you, in terms of whether they are absolutely needed or not.
As a rule, software updaters can be turned off without many ill effects.

There is another side of this equation, however. And that has to do with the amount of RAM your computer has on it. You see, when a program opens up, it opens up into your RAM memory. Everything runs in RAM, from Windows itself, to Norton, to you name it - all of it. If you do not have much RAM then you will see poor performance from your computer such as slow startup times, slow response times to your commands, etc.
Go to: Start > right click on My Computer > Properties
to see how much RAM you have installed. I recommend at least 512 MB for the average home user. Although it is possible to get fair performance from and XP machine with 256 MB of RAM, it is becoming rare, as Antivirus and Antispyware and Firewalls and many other programs are run resident now. 512 MB is usually enough, but perhaps even more will be needed.
