Endpoint Protection

What is the solution for getting and end to lucallbackproxy.exe bogging down my PC? I am running Symantec Endpoint Protection 11.0.2000.1567 on Dell Lattitude D620 running XP.

That 11.0.2 build is very out dated. The current release of SEP is RU6MP1. I would recommend to get that build installed and see if the issue is still occuring as there have been many changes since the release you are running (approx. 10 releases).

LuCallBackProxy is a component of LiveUpdate and is responsible for downloading the individual LiveUpdate files as well as some limited post download processing.

The latest version of SEP is RU6 MP1, however you cannot directly upgrade to it from the current version that you are running. You might have to do a fresh install.

Symantec Endpoint Protection RU6 MP1 (11.0.6100) provides fixes since the release of RU6 and RU6a. This maintenance patch cannot be installed over any versions of Symantec Endpoint Protection or Symantec Endpoint Protection Manager prior to RU6. It must be installed over RU6 or RU6a.

If you are using Symantec Endpoint Protection Manager 11.0 RU6 and plan to leverage the Auto-Upgrade feature in the console to upgrade to a new client build , read the following Knowledge Base article on importing client packages:

This problem is fixed in Symantec Endpoint Protection 11 Maintenance Release 4 Maintenance Patch 2.

Since you will not able to download MR4MP2  Please upgrade to RU6

But recommended to go from 11.0.6 (RU6) than to RU6a

Avoid troubles and do 2 upgrades to the latest version, not just the one.

I have the same problem -- excessive disk I/O and high CPU util.

This problem started out slowly and over the past 6 months has increased to the point where my PC is locked up for long periods of time (10-15mins), usually during start up but sometime at random times.  CPU util has hit 99% (I have attached a screen print).  Disk reads have been over 12million.  Disk writes have been over 4 million.  Combine this with RTVSCAN running at the same time and my PC has been rendered useless!!

I have exactly the same problem on my IBM ThinkPad.

Both are running Windows XP, Service Pack3, with adequate memory and lots of free disk space (both the PC and laptop have over 50% free space).

Kurt G has said that "LuCallBackProxy is a component of LiveUpdate and is responsible for downloading the individual LiveUpdate files as well as some limited post download processing".  However, after sucking down my PC forever and doing a zillioin disk I/O's, none of my anti-virus def files were updated.  When I've run update manually, I've observed that update is a separate process. 

It really looks like LUCallBackProxy is doing a separate scan of the harddrive.

I've read a many of the write-up here as I could and found nothing that fully identifies or fixes this problem.

So, I've given up and removed (uninstalled) SEP.

For now and until I decide on another AV package, I'm running Microsoft Essentials.  It consumes a tiny fraction of the CPU util and NONE of the excessive disk I/O that SEP did, even when performing a full manual scan.  When I did a full manual scan using SEP, I could barely run any other application.  I have the option of throttling back the MS Essentials exe so that I can run even more applications at the same time.
