Save, Norton's LiveUpdater

It appeared in my taskmanager processing list suddenly after installing a keylogging software. On the news 1/16 or 1/17/06 there was report of Symantec admission of spyware loaded into their security package. Makes me wonder what's up?
   
i was wrong about saying that it slows down my computer...its a part of NAV..i figured there was some other porblem on my computer

Part of a bloated antivirus/internetsecurity suite. solution: uninstall nortons and find something better
  Craig  
Could be for Symantec LiveUpdater or a cloaked email worm, if it is found in system32
   
Live Update for Ghost
  Drew  
Turn off automatic live update. Now lucoms~1.exe should not execute by itself anymore, so if you have not initiated norton update manually,but still appears in the task manager it is a virus/worm disguised as norton.
   
Symantec Program. If people are experiencing lag, or poor performance because of it, it suggests a deeper problem that may require re-installation your Symantec software; Symantec would be happy to help you do this - most software providers offer free support for installation issues. Removing this program, or even shutting it down temporarily, may leave your PC open to threats - this is likely to slow your computer down more!!!
   
it uses a lot of capacity. Apparantly I am downloading a lot since 4 days and there is nothing else in my computer which could be the source of it
  Elianthe  
lucoms~1.exe is a file that imitates a luveupdate file. Search hard drive for file name and look at properties. if under prefetch with no properties, delete.
  Paul G  
It randomly appears on my computer and lags it, so i have to end it with Task Manager.
  Peach  
Norton live update, but sucks up memory
  Jimmy J  
It is definately spyware, If you open your Windows Task Manager, you can see it running. I have been copy and pasting to my Word for documentation and find that if I open the Task Manager, the guy or gal from India will jump off as they know I know they are on my system. Look at your history's and trail and you will see their footprint. Symantec does not control the subcontractor to their subcontractor in India. After assistance from their help desk last year, I found my India "friend" signed on my computer twice. I had to call another software company to kill the stolen link program.

It's part of Norton's Live Update, but mine seemed to be eating at my cpu speed. Just adjust settings. You can even manually start update vice the automatic option. No biggy, either way.
  John  
It is part of NAV update, but on my comp. it runs even if the auto update is turned off. but NAV says update is already being run by another user when lucoms is running, so pretty sure its a bug in their system.
  andrew  
LUCOMS~1.exe is annoying. It launches upto 10 other Localcallbackproxys bogging my system for a short while, it also does this several times and task manager cannot stop mine. Bootsector begone with her!
  Cylas  
It seems to be a Norton thing for live update for me as well. it comes up when i start my computer in the process list but after i few mins goes away. i did a search and all references to it have to do with norton, now if you dont have norton then you probably have the virus.
   
LiveUpdate communications for any symantec product.

Remove Symantec and Install Another Software. Symantec is nothing but problems.
  Nathan  
Turn on computer, walk away for a half hour, it's work will be done when you get back
  Bob  
as far as I can tell its just another pesky lefdtover from norton deletion
  Lilly Rose  
It is the process for LiveUpdate of Symantec Endpoint Protection 11' s new virus definitions and protection signatures.
