AUpdate.exe
(Symantec)
Automatic LiveUpdate Module. AUPDATE is entirely to do with Nortons LiveUpdate, whether you have Norton AntiVirus, Norton PCAnywhere, Norton Personal Firewall, or Norton Internet Security. It only appears in your Task List if you have configured your Norton software to update automatically and you happen to bring up the Task List at the very moment that Nortons LiveUpdate is in the process of downloading updates.
Recommendation :
Do nothing. As soon as LiveUpdate finishes downloading updates in the background, AUPDATE will disappear from your Task List.
