Mistakes made when editing the registry can render your PC inoperable and cause irreparable damage to your operating system.

Causes of dysfunction in ESET NOD32

The problem in question appears both in licensed versions of the program and in its pirated versions.

There may be several reasons for its appearance:

Invalid license to use the antivirus. An incorrect license key was entered or the license failed due to various reasons;

Error downloading update files. May occur due to unstable Internet, random PC failure, incorrect proxy operation and other relevant reasons;

The virus signature database is damaged;

NOD32 antivirus conflicts with another antivirus installed on this PC;

The incorrect date or time is set on the user's PC;

The Windows Firewall blocks the antivirus from accessing the network;

There is no free space on the PC hard drive.

Let's figure out how to fix the module update error in GCD 32 on your PC.

Try "Test Update"

Switching the update type to “Test update” gives good results. To do this, go to your antivirus settings and select “Advanced settings.” Next, click on “Update” (on the left), and open the “Main” tab. Set the update type to Test Update.

Select "Test Update"

Now go to the “Update” section and click on “Update Now”. After the test database has been successfully loaded, switch the update type back to “Regular update” and try to update the database again. This may help get rid of the “Module update failed” error on your PC.

Problem with updating ESET NOD32 Antivirus. What to do?

Module update failed. Unable to authorize updates, please check the authenticity of your license. but my license is probably valid until 2020. What is the shorter problem then?

It’s great that, in principle, people are interested in this topic... 1. Check the free space on the disk where the Anti-Virus was, in fact, installed; judging by experience, there should be 300MB of free space.
It is also valid to check if there is a date and all the time in the computer. 2. Open the Antivirus program. Open the Settings section, click the Advanced/Advanced settings button (F5). 3. Advanced settings of the Updates menu (Left) - Open the Home tab. Change the Update Type Update Test - OK. (The Regular update option is selected by default) 4. Go to Update and click the Update now button. Wait until the test database is loaded. If the update was successful - disable the update type, Advanced options return to updates - OK. 5. Re-update the signature databases. ———————————————— I would like your problems, by the way. Kapot Abep

Virus signature error

During the update process, the antivirus downloads new data from the laboratory database about the status of malware and information about how to combat it. This can be done every day or even several times a day. If you constantly receive an error when trying to update your antivirus program either scheduled or manually, then it is possible that the problem is with virus signatures. For example, they are damaged, which makes it impossible to download new ones. To resolve the issue and both update signatures and ensure full protection, you need to do the following:

open the antivirus menu;
go to the “Settings” menu;
open the “Advanced settings” item;
find the “Updates” section;
in it, click the “Clear” button opposite the “Clear update cache” column.

After this, try downloading again. The problem must be resolved.

What to do if Nod 32 antivirus is not updated?

Greetings, dear reader. I have been approached more than once with the question : what to do if it is impossible to update the virus signature database, or an error occurs when downloading update files , or the antivirus is not activated by any key, etc. Therefore, I decided to describe in detail what to do in such cases. If you encounter this problem, I recommend following these steps:

1.If the antivirus displays an error message about updating the signature databases or an error occurs when downloading update files, the first thing you need to do is try to replace the activation key; it may have expired or been banned.

In order to replace the key you must:

Open Nod32 (right-click on the Nod icon, near the clock) and the main program window will open.

Click Settings

Click on program activation.

Copy the key and password from here and paste it here.

Click Activate.

2. If the program has been activated, but the signature database update error still appears, do the following:

Open Nod32 (right-click on the Node icon, near the clock) the main window will open

After the program has opened, press F5 on the keyboard. The setup menu will open.

In the left block of the window (tree structure of available settings), approximately in the middle, select UPDATE

In the right block of the Additional update settings window, the SETTINGS button in the window that appears, the HTTP PROXY tab

Select DO NOT USE A PROXY SERVER (this is done if your Internet is not really connected through a proxy server. Otherwise, you need to check the proxy server settings.) click OK

In the right block of the Clear update cache window: CLEAR button

ALWAYS reboot the computer
Copy the key from the list again.
Let's try to update again.

If the standard message “virus signature database is out of date” appears , as expected, you try to start the update manually, but when you start it says that the latest databases are installed and an update is not required. To get rid of this problem you need to clean some folders.

For Windows XP users:

C:\Documents and Settings\All Users\Application Data\ESET\%Product%\Updfiles

C:\Documents and Settings\%userprofile%\Local Settings\Temp

C:\WINDOWS\Temp

For those who have Vista and Windows 7:

C:\ProgramData\ESET\%Product%\Updfiles

C:\Users\%userprofile%\AppData\Local\Temp

C:\Windows\Temp

The reason that the antivirus is not updated may be that a virus has entered the system and is blocking update sites. Thus, our antivirus will not be able to update. Therefore we need to do the following:

Open settings using the F5 key and select the Updates section there.

In the “Update server” item, you need to select Edit and enter in the “Update servers” field https://89.202.157.139/eset_upd

press the add button and confirm adding After updating, it is advisable to conduct a full scan of the computer or use external antiviruses to identify the problem.

5. If the antivirus does not start after loading the operating system , this is a clear sign that a virus has entered the system. In this case, you need to download the cureit or Kaspersky Virus Removal Tool and perform a full scan of the computer.

Issues with ESET NOD32 license

This antivirus operates in a license format, which is provided for a certain period, for example, 1 year. Without it, you cannot download the latest updates. Therefore, if your license has expired, then simply buy a new code to renew. However, it may happen that an expiration error will start appearing (for example, digital signature not found) even if your license is still active. This happens when there is a failure when trying to receive data from the server. You can try updating the program. Or go to the antivirus menu and click the “Activate full version” button by entering the existing product code. After this, the period should be restored.
