Part of Norton/Symantec live update for virus defintions

If it's the real exe from Symantec then it's part of Norton Internet Security
  Tim  
My PC shows that Symantec installed it to the Symantec directory. So I guess my file is OK

Symantec AntiVirus update

Belongs to Symantec Internet Security Live Update. If you use this products, then it's okay. However, after completely removing the Symantec Internet Security Suite, this program remains to nag you about updates. It has many hooks into the registry, and is very annoying. I consider this to be adware behavior and should not be tolerated.

Norton update
   
Its a pain in the arse as it takes all of my cpu and i cant do nothing while its running...i`d rather not have norton internet security...The free antivirus ones are much more better

Best practices for resolving LuComServer issues

A clean and tidy computer is the key requirement for avoiding problems with LuComServer. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
