asked for permission to access the internet only after installing mcafee security center. possibly to report that to symantec.
It is part of Norton, but an annoying one. It causes the same error message (subscription expired) to pop up literally every 20 seconds. Whatever you press it just comes up again 20 secs later. Annoying. But by closing the prog this stops. I went the whole hog and removed it. Everything is fine.

It's a bugger. It kept asking me about an expired registation. When I say kept, it popped up a message box every 15 seconds or so. The ONLY way to stop this was to terminate this process.

i had the same prob when i installed mcafee anti virus msafe told me to un install it ... and well i did then it tore up my registry and EVERY single program (including the on button on case,right clik, and task manger! all because it nos the rival companie is mcafee and its the bug found by MCAFEE and deleted.!
This process notifies Windows Builtin firewall to shutup and let Norton Security Center do the job of firewalling - If you do not have Norton Internet Security / Symantec Firewall installed then it's most likely a trojan

uses up more than 75% of my cpu usage
SYMWSC.EXE is a replacement for Windows Security Center and is not needed. The removal of this program will cause the Original Windows Security Center to take over the job
References to symwsc.exe, symscwb.dll, ccwebwnd.dll, and symidslu.dll will appear in the registry if NAV 2002 (and later?) has expired. None of those files are present on a non-expired installation. Those files seem to be downloaded by NAV when it has expired itself. They should all be present in a Symantec or Symantec Shared subdirectory.
This is a file directly related to Norton Internet Security and Antivirus. It reminds you of an expired product Every 20 seconds, and prompts you to renew subcription. Very annoying, I ended it as a process in the Task Manager and I see no problems with my Firewall or Anti-virus. It's one of those annoying, borderling "big brother" programs constantly bugging you to spend more money with their products.

Mine was taking up 50% of my CPU yesterday and I'm scanning to make sure its nothing serious
it takes up too much memory , I removed norton and this stayed behind so I installed trend micro and now I have to stop it each time I turn on my comp.
service manager
symwsc will often have memory leaks and will slow down a computer until it is terminated.
it is malicous pop up that installs itself on your pc i have had to talk several friends through deleting it such a pain

Appears to be a remnant of Norton. I too installed Trend Micro and things went south real quick. Drove CPU usage up to 100% all the time. I just went into Add/Remove programs and removed all Norton and Symantic programs and seems to have fixed the problem.

Best practices for resolving SymWSC issues

A clean and tidy computer is the key requirement for avoiding problems with SymWSC. 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 SymWSC.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.
