Looks like you need it Dave its part of Nortons live update process
Lucomserver
Lucoms~1 LuComServer.exe
Lucoms~1.exe
(Symantec) LiveUpdate Engine COM Module. LUCOMSERVER is entirely to do with Norton?s LiveUpdate, whether you have Norton AntiVirus, Norton PCAnywhere, Norton Personal Firewall, or Norton Internet Security. It only appears in your Task List if you happen to bring up the Task List at the very moment that Norton?s LiveUpdate is checking whether there are software or virus definitions updates, or if LiveUpdate is in the process of downloading updates (LUCOMS~1 is the 8.3 DOS name for the program and only shows as such if somehow your system has lost its ability to display long program names).
Recommendation :
Do nothing. As soon as LiveUpdate finishes LUCOMSERVER will disappear from your Task List. If LiveUpdate is not allowed to finish (your connection to the Internet is closed), or is waiting for end-user input, LUCOMSERVER will remain in the Task List.
