It's part of Norton, an anti-virus which was suppose to protect my computer. It made my games incapable of connecting online and when I uninstalled Norton, it took with it a lot of my programs. They completely vanished.
That even if u stop the process running, so u are able to delete it, kaspersky will inform u that it is still installed, I also know its not a trojen. I'd rather not use my computer than be forced to use a specific company, theres really no need for it, if the products are so good. Still, I have the problem.

I haven't used Norton in years and recently have been trying to clear all unnecessary files. I was looking at my install/uninstall programs list and saw Symantec listed with a bunch of odd numbers and letters. I clicked to uninstall... As I did this my McAfee service popped up and said it stopped and blocked 2 trojans by the name of Artemis! (etc.)... Listed the file name as SymLCSVC.exe and a process in the Windows system as MsiExec.exe
Essential Symantec File
The File Is a left over extension of the use of notrton virus protection. After realizing the process is still in use i couldn't delete, So i opend up task manager and removed the task called symlcsv.exe which will allow you access to go into the file directory. C/program files/common files/ symantec shared. There just delete the folder. BUT ONLY DO THIS IF YOU DONT USE NORTON ANTIVIRUS. YOU NEED THIS IF YOU DO. That all i know is how to delete it.
Norton Symantec tool
don't use norton and you most likely won't get this problem. Uninstalling norton not effective means of solving issue. norton uninstall tool doesn't work. i rated it important if you have norton installed but really it's not if you use something else.
Comes also with Norton Ghost 10

Best practices for resolving symlcsvc issues

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