Completely harmless. It should be helping your computer!
It's part of Norton Internet Security
its a proxy service for norton internet security
It hogs CPU resource (98%!)
its eat a larg space of memory and cpu usage
Belongs to Norton Internet Security
Some times it takes 98-99 % CPU usage and my system becomes very slow. I dont know what to do now.
Part of Norton Internet Security. Quite harmless but takes up loads of virtual memory and slows your computer.
harmles in that it is part of norton antivirus, but eats up a chunk of CPU sometimes
Part of NIS 2003, memory hog
Seriously eats up my system resources
eats memory !
Tried turning it off, but my internet stopped working... If I left it on, it slows my computer down...
takes 99% of my CPU resources
It causes my computer to freeze for a long time while processing
Error with 99% CPU usage, you could lose all your edited files.
Its a part of Norton Security and if it hogs CPU 98%, first switch off Internet security then end the process and then switch the internet security back on
It hogged 50% or more of my cpu for almost an hour after I started my computer, and then it stopped and stayed at 0%. God only knows what it was doing all that time. I'm still suspicious because in the task manager, it CCPXYSVC.EXE was in all caps. It used 5,000 K of memory according to taskmanager.  
Not "dangerous", but has suddenly begun sucking up CPU 90-100%, for about half-hour, then stops
Resource hog indicating it is poorly written and a threat.
It hogs the cpu and shuts down everything else
It uses 95% of my CPU slowing and sometimes seemingly stalling all other processes.
Makes all other apps fail to run properly (uses 98% cpu). However if i end the process, internet will not function.
100% CPU usage
Symantec Technical Support says you have to upgrade to latest version since they are no longer supporting the 2003 version, despite the fact that they continue to sell subscriptions to it. Nice.

Seems like I have the same prob. Same thing happened last year when my subscription was due. Paid the money, got the years subscription an all was well. It's happening again. Subscription over due, Problem with slow machine. Norton does this to make you pay money.... End. Bye bye Norton. Been great over the years but not any more.
Had my CPU pegged at 100%!!!
Internet doesn't work without but it makes my pc slowly. It sucks!
"ccPxYSvc.exe", as listed in Window$' Task Manager, is an essential component to Norton Internet Security, and will severely inhibit NIS' ability to protect your computer if the process is ended. There are two things that a person with administrative privilidges over the system in question and admin. access to NIS (Especially if Parental Control/s is installed) can do to aleviate the CPU/s from maximum usage. ONE) Even if the system in question has only one user, and is set up to auto-login with user/pass, log off, and wait for the system to be idle, then shut down the computer (not restart)
Used during AVG Anti-Virus complete scan.

If you want to live with Norton and have the ccpxysvc.exe over utilizes cpu problem try to restart the Symantec Proxy Service. 1) Go to Control Panel 2) Go to Administrative Tools 3) Go to Services 4) Right-Click on Symantec Proxy Service 5) Click Restart Hope this helps,
Needed for Norton Internet Security to run. Need to Uninstall Norton Products and Re-Install.
This is part of Symantec's Norton Personal Firewall 2003. When it goes wrong it eats system resources (CPU at 98%) and makes the PC so impossibly slow it has to be rebooted. Force stopping it prevents browser connecting to the internet, but does not prevent email being sent and received.

Best practices for resolving ccPxySvc issues

A clean and tidy computer is the key requirement for avoiding problems with ccPxySvc. 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 repairing of your installation or, for Windows 8 and later versions, 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 ccPxySvc.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.
