Blazes along consuming 99% of CPU until I re-start my laptop which is a 2005 era VAIO running Windows98 and..... Norton Anti-virus.

Running an old system with xp and with Norton anti-virus 2005. From Task manager: CPU usage is at 100%. CCAPP is using all available memory. Browsers are useless. After reading around (on another machine), I decided to uninstall Norton. When I did this, I was able to do a normal shutdown, and when I restarted CCAPP was gone, and the system was really fast - even the browsers.

I removed Symantec/ Norton antiirus software from my laptop because it was hogging huge amounts of cpu time. Now on startup I get ccApp.exe could not be found. System runs far better without the AV software and I don't care at all whether ccApp can be found or not!!!

Not dangerous, just a resource HOG

It's part of Symantec-Norton. I uninstalled the Norton but it's still there and every time I shut down, it wastes time.

slows my PC to almost a stand still. its awful.

Open "Symantec Client Firewall" -- Status and Settings -- Turn Ad Blocking OFF (ON turns ccApp.exe on and hogs CPU)

It's Symantec/Norton garbage, get rid of it and use a REAL AV/security program! The detection rate for symantec products is relatively crappy, the bug rate is incredible. Some version don't even add properly when showing the download size for various updates. Suggest Avira, Eset, or Avast. But before you do that go get the Norton Removal tool to get rid of the Norton junk that norton can't uninstall!!

Best practices for resolving ccApp issues

A clean and tidy computer is the key requirement for avoiding problems with ccApp. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ccApp.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
