For many Internet users, the question of antivirus does not arise, and they give their preference to Kaspersky antivirus. It is reliable and modern, but it also has some problems with updating the software base. For this reason, the level of computer protection against viruses is reduced. So why isn't Kaspersky updated?

Possible reasons

The reason may be due to the fact that another anti-virus solution was previously used, which was either already installed or was not completely removed. Maybe the previous antivirus was removed correctly, but the recovery protocols were left behind. This may be the reason why Kaspersky does not update the databases. This problem can be solved only by getting rid of traces of previous antiviruses completely, that is, deleting them. If you can’t handle it yourself, then it’s better to turn to various programs that will delete unnecessary files. You need to install a powerful garbage remover. Only then can you reinstall Kaspersky Anti-Virus and update it.

Demo and unlicensed version

Another reason why Kaspersky databases are not updated is that your product simply does not include such an option. Maybe you have a demo version of the antivirus, or maybe the version is limited in time. You need to purchase the full version. To avoid being distracted by such problems, install automatic updates. The second reason why Kaspersky Anti-Virus is not updated is that you purchased an unlicensed product.

Many PC users are not psychologically prepared for the fact that some kind of virus may appear on their computer. But in most cases, Kaspersky Anti-Virus is not updated precisely because malicious software blocks actions, the OS may become severely slow, glitches during operation, the browser stops working, and spam is sent.

If your antivirus fails and Kaspersky antivirus does not update, don’t worry, it’s not the end of the world.

• KasperskyVirusRemovalTool is a useful program to quickly scan your computer and clean it of malicious visitors.
• Curelt software product. You need to download this program and run it.

After checking with such programs, your computer should start and start working normally.

The popular Kaspersky anti-virus reliably protects the system from various threats, but its successful operation requires constant updates. New viruses and other malware appear every day, and by skipping updates to their databases, you risk that your defender will miss a “fresh” virus that will infect the entire system. To prevent this, you should know the specifics of the Kaspersky update settings.

If you have just installed Kaspersky Anti-Virus, you should update it immediately, since even the latest versions of the program may come out with outdated databases. After installing the antivirus, you will see a settings window where there will be an “Update” option. Click this button to update. In the next window, confirm the action by clicking on “Update”.

Your databases have been updated. Now you should configure how to update your antivirus. To do this, in the main menu of Kaspersky, click on the “Settings” button located at the bottom. In the menu that opens, select the “Advanced” tab from the list, then click on “Update Options” on the right.

In the menu that opens, select automatic download and installation of new versions of the program. These are not virus databases, but corrected and modified antivirus modules. If you don't want to change anything, check the "Don't download new version" option.

Below are the settings for the update launch mode. They relate directly to virus databases and therefore require special attention. You can set automatic updates if you don't want to bother with updates. If you want to keep everything under personal control, install a manual update. This can be convenient, since automatic updates can start at any time and “eat up” computer resources at the wrong time.

You can also set your antivirus update scheduler to check for updates daily or weekly. In the first case, do not forget to indicate a convenient time for such a check; in the second, also the day of the week. For example, every Monday at 20.00. Don't forget to click on "Save".

If there is no Internet or its slow and unstable operation, you can update the antivirus databases in a special way. To do this, download the KLUpdater utility from a computer where the Internet works normally. This can be done from the official website kaspersky.ru. Unpack the archive into a folder and run the KasperskyUpdater.exe file, which will download database updates to the Updates directory. In the program menu, select Russian for the interface. To do this, go to Settings – Service and in the language field, select “Russian” from the list. In the main menu, click "Run". After downloading the updates, move the Updates folder to a computer where there is no Internet. All that remains is to specify the path to this folder in the antivirus update settings. In the main menu, go to “Settings” - “Advanced” - “Update options” and click on “ Configure update source”. Click on “add” and specify the path to the Updates folder.

Kaspersky Anti-Virus – the most popular antivirus currently existing. It provides its users with complete protection in real time, ignoring most existing viruses. However, if the antivirus cannot update its antivirus databases in a timely manner, then all its protective ability goes down the drain.

Below we will look at the main reasons that may affect the inability of Kaspersky Anti-Virus to update its databases.

1. An antivirus was previously installed on the computer. Many users know that you cannot use two antiviruses on your computer at the same time, because... This often leads to them starting to conflict. But few people know that uninstalling an antivirus even through the Control Panel does not always go completely, and traces remain on the computer that can also conflict with Kaspersky.

In this case, you have two options:

1) Almost every self-respecting antivirus manufacturer offers a special utility on its website that will completely remove the antivirus from your computer with all accompanying files.

2) Use a special computer cleaning program, such as CCleaner. CCleaner allows you to remove programs along with all the garbage they leave behind. And besides, using CCleaner you can remove not only antiviruses, but also any other programs.

2. You are using a demo version of Kaspersky. The trial version of the antivirus cannot receive database updates, so go to the official Kaspersky website to.

3. You are using an unlicensed version of the antivirus. Anti-virus database updates come from Kaspersky servers, so the system can check the validity of your license key. If the program detects a fake key, then you will be immediately denied updating the database.

4. Your key has expired. If the paid version of Kaspersky has expired, the program will not update the databases until you correct the situation. Although, as a rule, Kapersky likes to remind us of this often.

5. A virus has entered the system. Paradoxical as it may seem, the reason for the failure of the Kaspersky update could have been an infected virus that edited the file "hosts" . You can fix the problem as follows: find the contents of the original “hosts” file on the Internet (it always looks the same) and open the “hosts” file using Notepad in the C:\Windows\System\drivers\etc\ folder. Return the file to its original form, save the changes and restart your computer.

6. Unstable Internet. If your home Internet is not stable, downloading updates may be interrupted periodically. However, if downloading updates has stopped at 99%, then you should wait. Usually at this stage the installation of the bases occurs, so the remaining time can take up to 15 minutes.

7. Proxy activated. If you have enabled work through a proxy in your settings, then it must be disabled while installing anti-virus databases.

According to statistics, most Internet users prefer antivirus from Kaspersky Lab. It meets many requirements and is one of the most reliable antiviruses available. But sometimes it happens that the antivirus cannot update its software databases, and this may result in a decrease in the level of protection of the user’s PC.

Speaking about the importance of updating your antivirus, it is worth noting that new types of malware appear every day that can cause serious harm to both your PC and personal information.

There are main reasons for this problem:

1. The most common reason is another antivirus was installed on your computer , which could leave “tails” behind it. These tails can conflict with Kaspersky antivirus. Accordingly, to solve this problem it is necessary to find these tails in the computer and remove them. If you could not find them on your PC yourself, then various programs that specialize in deleting just such files will come to your aid. Install a similar program and remove all junk from your computer. Once the removal is complete, you need to restart your PC and try updating your antivirus.

2. The second possible reason for the inability to update the antivirus is the one you are using the product does not support updates . This can happen if a trial version (demo version) of the antivirus is installed on your computer. To solve this problem, you need to purchase the full version of the antivirus on the official Kaspersky Lab website. To avoid being distracted by constant antivirus updates in the future, check the box next to “Download and install updates automatically,” which can be found in the antivirus settings.

3. Third reason - An unlicensed version of the antivirus is installed on your computer . Because Since antivirus updates go through official Kaspersky servers, they can track your antivirus license and block updates. This problem can be resolved by purchasing a license on the Kaspersky Lab website.

4. Kaspersky may not update if the antivirus the key has expired . And here the solution to the problem is extremely simple: buy a new key on the developer’s website.

5. The next reason may be edited "hosts" file , which is located at: C:\Windows\System\drivers\etc\. By changing the structure of this file, the virus can block access to Kaspersky servers. To solve this problem, you need to find the original hosts file, for example, on Wikipedia, compare it with the contents of the file on your computer (open using the standard Notepad program) and edit it if necessary.

6. It is possible that the antivirus cannot update due to unstable connection Internet networks. In this case, your update may be interrupted at some stage of the download (for example, 85%). In this case, you need to restart the update download. If the antivirus update has stopped at 99%, then you need to wait a little longer, because... At the final stage, installation may take up to 10 minutes.

7. Also, Kaspersky may not update if Work via proxy is enabled in the settings . In this case, you need to disable the proxy mechanism (if it was used before).

Kaspersky Lab Antivirus is the most famous antivirus. Thanks to timely updates, a huge anti-virus database and powerful security systems, the anti-virus has won the trust of a huge number of computer users. But even in this program errors can occur. In particular, I will look at the problem of the inability to update anti-virus databases and provide tips for resolving this error.

Why should anti-virus databases be updated promptly? Imagine, every day hundreds of thousands of hackers operate on the Internet, inventing new ways to penetrate your computer. But Kaspersky Lab is not asleep, trying to detect new viruses and add them to the database. If the database is not updated in a timely manner, the antivirus may not detect a virus program that is trying to attack your computer.

The most common problems that can affect the inability of the antivirus to update the database:

1. Most often the problem is that antivirus from another manufacturer was previously installed on the computer . When deleting an old antivirus, a program may leave behind so-called tails that can conflict with Kaspersky antivirus. Therefore, your main task is to try to find these tails on the computer and delete them. If you couldn’t do this on your own, then there are a lot of programs on the Internet that are based specifically on removing programs, including their traces.

There is another way. Almost every reputable antivirus manufacturer has released a special program to completely remove their antivirus from a computer. Go to the official website of a used antivirus and download the remover program.

2. The second reason may be that your the antivirus simply cannot receive updates . And perhaps this is for one simple reason: a demo version of Kaspersky anti-virus is installed on your computer. It is easy to solve this problem, but to do this you will have to go to the official website of Kaspersky Lab and part with a certain amount of money for the full version.

3. The third reason may arise if you are using an unlicensed version of Kaspersky antivirus on your computer . Database updates come from Kaspersky servers, which can check the antivirus license. If they notice that you are using a free antivirus, you may simply be blocked from accessing updates. The solution is simple - purchase a license.

4. Also a problem >may involve the expiration of the key, although, as a rule, the antivirus often warns about this. If this is the case, you should renew the key and download updated databases.

5. The next possible reason is edited "hosts" file . This file is located at the following address: C:\Windows\System\drivers\etc\. The file may be modified if a virus has entered your computer. If the structure of this file has been changed, the antivirus may be blocked from accessing updates. To fix this problem, you need to open the file using the standard Notepad program and compare the contents of your “hosts” file with the original contents of the same file, taken, for example, from Wikipedia. If necessary, edit the file, returning it to its original form, and save the changes. Now restart your computer and try downloading updates.

6. Sometimes downloading updates can take a while unstable internet connection . In this case, the download is usually interrupted at some stage, take, for example, 75%. Cancel and restart downloading updates. If the download has stopped at 99%, then you may need to wait some more time, because... This step includes installing updates, so it may take up to 15 minutes.

7. If in your settings proxy work enabled , then you need to disable it for a while, because this can also affect the occurrence of database update errors.
