3rd party update servers will work with most NOD32 versions. The patch will only work with 3.0.621 and above. DO NOT use the patch on any versions below 621. We strongly recommend you read our updated article regarding NOD32 AV with unlimited updates here.

Here is some good news for NOD32 users who are tired of getting their keys blacklisted. If you follow the method described below, you will no longer be needing a key to update your copy of NOD32 Antivirus 3.0 or ESET Smart Security (and this works with trial versions). The process does not involve cracking or doing any sort of modification to the core files of above mentioned programs.

How to set up NOD32 Antivirus 3.0 and configure a 3rd party update server:

For an overview of ESET NOD32 Antivirus 3.0 features see this article.

1. Download NOD32 Antivirus 3.0 trial version from here.

2. Install the program with default update parameters. Once the install is done and reboot is completed, double click the tray icon to launch NOD32 control center.

3. By default, NOD32 interface will be switched to Standard mode. You will need to set this to advanced mode. Click on "Setup" in left hand panel and click on "Toggle advanced mode". Answer yes to the question.

4. Several new options will appear when advanced mode is toggled. Click on "Enter entire advanced setup tree" link. A new window will open.

5. From the left hand panel in new Window, Click on "Update". Click on the "Edit" button. A new window titled "Update servers list" will pop up. In the "Update servers" text field type http://eset.com.sapo.pt and press "add". Press ok once to close this window.

6. You will have the update setup window still open. In the "Update server" drop down box, select the server you entered in Step 5 (I.E- http://eset.com.sapo.pt). Delete everything in "username" and "password" text fields and press ok.

7. You should now be able to update NOD32 without issues. The server which you just entered does not validate usernames or passwords so there will be no fear of trial expirations or keys getting blacklisted.

What happens here is that you are downloading updates from an update server hosted by a 3rd party instead of ESET's servers which require authentication and a paid subscription. According to our experience this server is secure. If you have doubts, you can compare the 3rd party server content with that of ESET's official server's using NOD32View tool and see for yourself.

How to set up ESET Smart Security and configure a 3rd party update server:

For an overview of ESET Smart Security features see this article.

The process of configuring a 3rd party update sever to ESET Smart Security is similar to that of ESET NOD32 Antivirus (described above). 3rd party servers for ESET NOD32 Antivirus also works with ESET Smart Security. Download and install ESET Smart Security from here and use the method described above to get free updates.

Note: We cannot guarantee that these update servers will stay online forever as they are not operated by us. If you find that your ESET product is not updating or if you are getting constant server connection failure warnings, drop a comment here and we'll do our best to help you.

    I followed the instructions you've posted but I still couldn't update. I clicked on the server link and there was a "Download the official Fix here" blinking red. I download it and when I opened the "hot fix" program, it went onto a "DOS" which it said "This fix will automatically add and select a mirror update server for ESET 3.x Versions (Smart Security and NOD32 Antivirus) and clean the username and password to prevent any errors. Press any key to continue" once I did that, the update worked! But I'm still uneasy about the "hot fix" they made me download... Did anyone else have the same problem as I did? Anyone know if this "hot fix" is legit? I scanned it with AVG (before I deleted it) and also on ESET. Both didn't find any spyware, virus, trojan, etc. Can someone confirm this? Thanks.

  2. Lightning_Struck_Tower // 1/03/2008 12:29:00 PM  

    Why did you download the hotfix in the first place? It is not required. Merely setting the server name as instructed in the article will suffice.

    Anyways we checked out the hotfix and can confirm that its not harmful. It enables one click addition of the update server into nod32 via a registry key. Its safe.

    But still no need to download a fix just set the name as instructed in the article.

  3. Ahl // 1/03/2008 09:00:00 PM  

    I did what the instructions said but it wouldn't let me update but I must have left something out. Thank you for checking the hot fix out.

  4. Redd // 1/04/2008 02:51:00 PM  

    Ahl:You need to download the latest build of NOD32 or Smart Security. The hot fix/the method specified above will then work. The build should be no older than 3.0.600.

  5. vishnu // 1/04/2008 05:27:00 PM  

    but on 4th january 2008 when i updated the eset smart security 3.0 it updated to 2763 version but the original version in eset.com was 2765 . Help guyyyyys

  6. Redd // 1/04/2008 08:37:00 PM  

    ESET releases updates atleast twice a day. The other website (the one you use) cannot afford to do that. Waiting for another day wont kill you. If it does, buy an original license in your next life.

  7. Big // 1/06/2008 07:34:00 PM  

    Hello amigo!!
    My question is a bit more ambiguous!! Is there a more permanent solution to ESET update issue for people how don't like to spend money? (i.e. finding some username&password that are authentic and work with ESET servers rather than depending on the mercy of 3rd party server)
    If yes, please shoot me a msg. or post it here!!!

  8. Sina // 1/07/2008 03:33:00 PM  

    this update server is excellent

  9. Scott // 1/11/2008 05:47:00 AM  

    this server now appears to be down. Got this today when i updated.

    "Virus signature database could not be updated. File not found on server."

  10. Lightning_Struck_Tower // 1/11/2008 11:37:00 AM  

    scott, retry after a while or use the server below:


    Or for a set of licence keys updated daily try http://www.nod321.com/

  11. sachithra // 1/11/2008 12:47:00 PM  

    Hey ur new server ddnt work 2 me...
    why ??

  12. Lightning_Struck_Tower // 1/11/2008 01:04:00 PM  


  13. Big // 1/11/2008 08:23:00 PM  

    You will never find a permanent solution to these proxy servers! they all will die some day, eventually!!

  14. Lightning_Struck_Tower // 1/11/2008 11:13:00 PM  

    KM92 has updated his page explaining why the server went down. Apparently there is a new patch out there :)


  15. Lightning_Struck_Tower // 1/11/2008 11:18:00 PM  

    If you dont like the patch try:


    Make sure your virus DB actually gets updated most of these servers will report "no updated needed" when they go bonkers. ESET usually releases updates once every two days and if your app says no update needed for more than 5 days its time to change the server.

    btw the patch mentioned in previous post works.

  16. TEAM FILEnetworks // 1/13/2008 06:25:00 PM

  17. Sina // 1/13/2008 11:33:00 PM

    3rd party server working as of 10/8/08.
    Updates are delayed by one day.


  27. Александр // 8/27/2008 06:59:00 PM  

    Hey guys... After release of 26/08/2008 update all third party update servers do not respond. But declaring "could not connect to server" after half a second of trying makes me think that content of latest update is blocking connection with third party server. Any suggestions? (ESS v3.0.630.0 TemDono FIX v 1.1)

  28. Jarai Csaba // 9/02/2008 10:53:00 AM  

    Thanks Lighting!


    works fine (at least until now 2008.09.02)

  29. Astral // 9/08/2008 09:32:00 PM  

    Thank you for this stuff.
