LiveUpdate incorrectly displays "All Symantec products and components installed on your computer are currently up to date"

LiveUpdate is part of Symantec's suite of antivirus products and is used for various programs to keep the software up to date for things such as virus definitions and product patches. Most of the time it runs in the background and is pretty hassle free but sometimes you will want to run it manually to make sure everything is up to date.

When you run LiveUpdate for Symantec AntiVirus, LiveUpdate displays the message "All Symantec products and components installed on your computer are currently up to date. Remember to check for new updates frequently." However, you are certain that more recent virus definitions are available from LiveUpdate.

Verify that the Symantec AntiVirus service is started

New virus definitions that have been downloaded cannot be processed if the Symantec AntiVirus service is not started.

Delete the contents of the Downloads folder

The Symantec\LiveUpdate folder contains settings and configuration files for LiveUpdate and one or more subfolders. One of these folders is Downloads. In some cases, the files or subfolders in the Downloads folder may be damaged.

**Do not delete the Download folder itself, only its contents**

To delete the contents of the Downloads folder

1: Start Windows Explorer.

2: Click the View menu (Windows 95/98/NT) or the Tools menu (Windows Me/2000/XP/2003), and then click Options or Folder options.

3: Click the View tab.

4: Uncheck "Hide file extensions for known file types."

5: Do one of the following:

  • In Windows 95/NT, click "Show all files."
  • In Windows 98, in the Advanced settings box, under the "Hidden files" folder, click Show all files.
  • In Windows Me/2000/XP/2003, uncheck "Hide protected operating system files." Under the "Hidden files" folder, click Show hidden files and folder

6: Click Apply, and then click OK.

7: Browse to the Download folder. The location varies depending on the version of Windows:

  • In Windows 98/Me, the location is C:\Windows\All Users\Application Data\Symantec\LiveUpdate\Downloads.
  • If Windows 98 was updated from Windows 95, the default location is C:\Windows\Application Data\Symantec\LiveUpdate\Downloads.
  • In Windows NT, the location is C:\Winnt\Profiles\All Users\Application Data\Symantec\LiveUpdate\Downloads.
  • In Windows 2000/XP/2003, the location is C:\Documents And Settings\All Users\Application Data\Symantec\LiveUpdate\Downloads.

8: Delete any files or folders that are contained in the Downloads folder.

In most cases, these will be Autoupdt.trg and Livetri.zip and maybe one or more folders. Delete them all.

Delete the Settings.LiveUpdate file

  • Browse to the LiveUpdate folder. The location varies according to the operating system:
    • In Windows 98/Me, the location is C:\Windows\All Users\Application Data\Symantec\LiveUpdate.

    If Windows 98 was updated from Windows 95, the default location is C:\Windows\Application Data\Symantec\LiveUpdate.

    • In Windows NT, the location is C:\Winnt\Profiles\All Users\Application Data\Symantec\LiveUpdate.
    • In Windows 2000/XP/2003, the location is C:\Documents And Settings\All Users\Application Data\Symantec\LiveUpdate.
  • In the LiveUpdate folder, delete the Settings. LiveUpdate file

Check the virus definitions for corruption (Symantec Antivirus Corporate)

Open My Computer or Windows Explorer and navigate to C:\Program Files\Common Files\Symantec Shared\VirusDefs and you will see files and folders similar to the following.

The numbered folders are named by date in the format YYYYMMDD

Check for the following:

  • Temporary folders identified by a .tmp extension are indications of corruption.
  • Any files in the Incoming folder are indications of corruption.
  • Open the Definfo.dat file with Notepad and verify that the "CurDefs" value equals the most recent folder and that the "LastDefs" value equals the previously dated folder.
  • Open the Usage.dat file and verify that the numbered folder heading inside the square brackets [ ] matches the folder referenced by "CurDefs" in Definfo.dat. Verify that there is a single square bracket.

Note: If you have other Symantec products running on the same system, there may be other entries in the Usage.dat file. It is important that all entries are under the same numbered folder heading.
