What to do when your favorite NOD32 antivirus suddenly stops updating and periodically pops up a message ESET NOD32 Antivirus: Invalid username and / or password? It is known that an antivirus that has not been updated for more than a month is no longer able to protect your computer with any quality. There are cases (though very rarely, but there are) when a delay in the update of several hours can allow an infection that might not have occurred, since definitions came with the following anti-virus databases that can prevent it. In this article I will talk about the reasons for this behavior and how to deal with it.
This situation occurs most often when the license expires and you need to contact the antivirus supplier to renew it: for Ukraine, for Russia, or in the closest computer store or electronics supermarket to your home. note that license Renewal is CHEAPER than buying a new one! Antivirus warns the user in advance about the expiration date of the license. New login and the password you need to enter into the antivirus according to this image:
1. Settings (or the "F5" key on the keyboard). 2. The "Update" tab. 3. Make sure that the update server is "Update automatically". 4. Enter a new username (login). 5. Enter a new password. 6. Close the window and try to update.
Customization ESET NOD32 Smart Security no different from eSET settings NOD32 Antivirus. Therefore, the pictures and technique presented here are valid for both cases, as well as versions 3 and 4 work, are configured and updated in the same way, although it is recommended to upgrade to latest version (currently version 4.2) for more complete protection.
It also happens when the number of users who are updated using one login-password exceeds the allowable number, in such cases the manufacturer blocks this license and all users, including those who paid for it, lose the right to update. This may not necessarily happen on purpose: there are trojans with the help of which hackers steal logins and passwords from the NOD32 antivirus (how to determine if there is a malicious software read).
Logins and passwords from "Chinese sites"
Besides the evil hackers, there are also good ones. Some of them (whose traces lead to the Celestial Empire) have figured out the algorithms by which the antivirus company generates logins and passwords and share this opportunity with us. ordinary users... To do this, we just need to know a few addresses of the sites on which they publish them, for example: hhuu.net, nod325.com, nod321.eu, trynod.com, tnoduse2.blogspot.com, trialkeysnod32.blogspot.com.
This just means that you are on the right track and the antivirus has blocked access to this site (who wants to lose money and will allow you to receive for free what they sell for money?) In order to enter here we need to temporarily disable antivirus protection
by right-clicking on the antivirus icon in the lower right corner of the monitor near the clock:
Or like this:
1. Enable advanced mode (if not enabled), or CTRL + M on your keyboard. 2. The "Settings" tab. 3. The "Antivirus" tab. 4. Item "Internet access protection" - Disable
Now we can go to these sites, which we will immediately do:
Site nodsj.com: 1. Announcement of today's logins and passwords. 2. Logins (username). 3. Passwords. 4. Link to full list of today's logins and passwords. 5. Link to yesterday's list of usernames-passwords
Site nod325.com: 1. Logins (usernames). 2. Passwords.
Now you just need to copy username (Username) ( be careful not to trap extra characters such as colon or space) and insert it into the antivirus, as shown in the upper figure. Likewise, copy-paste and password (Password). The username is that after the colon, it can be read either by the word EAV, as in this case the first login: EAV-48770263. Also, logins can begin with the word TRIAL- ... The password for this login is located directly under it in the same way after the colon.
If the update has not started, it means either we made a copy-paste mistake and made something wrong, or these logins-passwords are already blocked and we need to try to substitute others, or from another site.
The advantage this method is that we get an absolutely workable antivirus program that has not been cracked or modified in any way and behaves like an absolutely licensed one.
Disadvantage method - sometimes you have to enter new logins-passwords literally every day, so they are quickly blocked by the manufacturer. But sometimes you are lucky and the antivirus does not bother for several months, working normally and updating.
There are also other methods updates for this antivirus:
- using alternative update servers;
- using the method of unlimited extension of the trial period (Trial mode);
- using offline updates;
- from time to time, ESET holds various promotions and distributes promotional keys for 2, 3 and even as much as 6 months.
