LiveUpdate 2.0 Symantec Corporation

What is LiveUpdate Symantec Corporation?

LiveUpdate is an application developed by Symantec Corporation that downloads and installs security updates (such as spyware, firewall, or antivirus signature files) and software patches. A valid subscription is required to use Symantec LiveUpdate. Symantec LiveUpdate can be run in Interactive Mode or in Express Mode. In Interactive mode, users decide which updates to download and apply. Express mode will download and apply all applicable updates. LiveUpdate also runs in Express mode silently in the background. Once all updates are downloaded, Symantec LiveUpdate will begin the process of installing them.


During setup, the program registers itself to launch on boot through a Windows Schedule Task in order to automatically start-up. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The primary executable is named luall.exe. The setup package generally installs about 29 files and is usually about 7.73 MB (8,100,640 bytes). The installed file AUPDATE.EXE is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered.
