Cannot Install Virus Update (Norton Antivirus)

When I run Live Update I get an error message (LU 9001) saying: "The virus definitions failed authenticiation. Run Live Update later." After following the instructions for using the  Symantec Auto Fix Tool (as suggested by Symantec as a way to solve the problem) I get a message that the update has been downloaded successfully. However, when running Live Update again, the latest virus definitions are still listed as NOT installed and when trying to istall them, the LU 9001 error message appears again.

What's going on and what to do about it ?

Grateful fo help !

Get rid of the resource-hogging Norton, install the free better-user-rated AVG:
http://free.grisoft.com/doc/2/lng/us/tpl/v5

Don't believe Norton is not well liked? Just look at the rating at CNET:
http://www.download.com/Norton-AntiVirus/3000-2239_4-10321099.html?tag=lst-0-3
(2.5 out of 5 stars, user rating)

Now look at AVG's rating:
http://www.download.com/AVG-Anti-Virus-Free-Edition/3000-2239_4-10503939.html?tag=lst-0-2
(4 out of 5 stars, user rating)

Besides, you gotta keep paying to use Live Update. AVG gives you free automatic or manual updates!

Look at this link first.  If that does not work below is the process I use to correct the issue.
http://service1.symantec.com/SUPPORT/sharedtech.nsf/0/14b7b0e7a8a63fbd88256ef3007d614c?OpenDocument

1. Uninstall Symantec Antivirus
2. Reboot computer
3 Go to Add/Remove programs and remove the program Symantec Live update, and any other that relates to Norton or Symantec.
4. Under c:\windows\Program Files  delete the directory called symantec
5. under c:\documents and settings\(Your user profile)\Local settings\Application Data remove the Symantec folder
6. Go to Symantec Website and download and run the cleanup tool.
7. Reboot the computer
8. Re-install the Software.

I have seen this a lot.  Seems like Symantec would have a beter way of getting it corrected.  This has worked for me in the past on customers computers.

Tried all the the suggestion from "tthayer", except...

"4. Under c:\windows\Program Files  delete the directory called symantec"

Reason: It could NOT be deleted (maybe because I also I have other Symantec products installed (Ghost)


" 5. under c:\documents and settings\(Your user profile)\Local settings\Application Data remove the Symantec folder"

Reason: Could not find it (I am using XP)

End Result:  PROBLEM UNRESOLVED = Cannot install the latest virus def. (for many days now.

Any other suggestion  (please) ?

try downloading the definition manually:-
http://www.symantec.com/avcenter/defs.download.html
select your version of av from the list
and click download updates

you will prabably want to download the *x86.exe file when run this should update your av definition files.

We use this sometimes on our symantec/norton corporate av software

If you open explorer and go to tools...then folder options...then click on the view tab....and check the box to show hidden files and also system files (It will give you a message but that is OK.  Then click on the button to apply to all.  You should then be able to see the directories.  Make sure since you have ghost installed as well that you do not remove the ghost folder under the symantec.  Also make sure the live update is uninstalled from the add/remove programs.  Then download the liveupdate from the website and install after rebooting.  It could be you need to install the latest version of live update.  The link is below.

I completely agree with Callrs about resource-hogging of Norton. It makes the system very slow and not worth it when you have better and effective free AV solutions available online. I use Avast in my computer and happy with that. The virus definition files update finishes in less than 20 secs on a connection speed of 56K

Hi,
Before throwing away NAV it would be sage if you checked for liveupdate updates. The problem you mentioned occurs sometimes due to liveupdate and the a/v package incompatibility.
Why dont you check out for newer versions in www.symantec.com/techsupp/files/lu/lu.html ?
Check it out. Hope it helped:)

You might need to update you subscription via Symantec. They have this stupid idea
that you have to pay for your software every year. Check and see if your Live Update Subscription
has expired. If it has, don't renew it. It's is cheaper to buy a new edition, that will include a
1 year subscription.

I had this same problem for months. Then, I went for AVG from Grisoft.
Much better. Free. And reliable.
