Why is Kaspersky Internet Security not updated? Why isn't Kaspersky updated? Main reasons. Manual update of Kaspersky without connecting to the network

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.

Most common problems, which may 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 special program For complete removal your antivirus from your 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. Solving this problem is simple, 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 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. Next possible reason – 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 resolve this issue, you must open the file using standard program“Notepad” 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.

Kaspersky Lab requires no introduction. This is one of the best (if not the best) developers of security applications for the operating room. Windows systems. Its antivirus and internet security products are the most popular and offer value for money.

After installing KIS, I activated the product by entering license key and then manually updated the database to the latest available version. And after that, I did not open Kaspersky, because I was under the impression that it would automatically load the database and would not require manual intervention, but I was wrong. About 5 days ago I discovered that Kaspersky does not update the virus database automatically and decided to find a fix for this problem.

I asked myself: why is Kaspersky not updated? And most importantly, how to solve this error?

The main reasons why Kaspersky is not updated

• The reason may be that previously another program was installed on the PC to protect against viruses, which could simply have been uninstalled incorrectly or incompletely.
• Sometimes, even if the program is correctly uninstalled, errors may occur because recovery protocols were left behind.
• This problem can be solved very simply: you need to properly clean up the remnants of the previous program.
• If you do not understand such things yourself, then use special programs that will help you delete unnecessary files.
• To clean up the remnants of such utilities, you will need a powerful program.
• After clearing the databases and recovery protocols, reinstall the program and try updating the databases.
• Also, the problem may be that the Demo (or unlicensed) version is installed.

This is the most important and with default settings, Kaspersky does not run scheduled scans or update the virus database when running on battery power. In short, if you charge your laptop battery when the laptop is turned off and always use the laptop on battery, this could be the main reason why Kaspersky is not updating the database automatically.

To configure Kaspersky to download and install updates while on battery power, you need to follow the steps below.

1. Open the window Kaspersky. Click the Options button in the lower right corner to open Settings.
2. In the left panel, click " Performance" to see several parameters related to Kaspersky performance.

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 databases software, and this may result in a reduction 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 treated 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 type hosts file, for example, on Wikipedia, compare with the contents of the file on your computer (open using the standard Notepad program) and edit 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... on 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).

Attention! After installation Kaspersky Internet Security 2016 does not provide complete protection. To ensure complete protection, run a program update.

Updating the program database is only possible with a valid license. You can buy a license (activation code) in the online store. To renew your expired license at a discount, use License Update Center .

If you encounter any problems while updating the databases, follow the steps described in the article Diagnosing update problems.

If you have any problems downloading the new version Kaspersky Internet Security 2016, download new version from the site Kaspersky Lab and install it manually.

1. How the databases are updated

When updating, the following are downloaded and installed on your computer:

• Anti-virus databases. The databases contain descriptions of threats and network attacks, as well as methods to combat them. Update your databases regularly and run a full scan.
• Software modules. Update packages fix program vulnerabilities, add new features or improve existing ones.
• New versions. The program by default downloads the new version to the computer and automatically installs “on top” of the current version.
  If you have any problems downloading, please download the new version from the website Kaspersky Lab and install it manually.

Databases are downloaded only for included program components to reduce the volume of downloaded updates and download time. When you enable the component, downloading the appropriate updates immediately begins.

2. How to update the databases

1. Make sure your computer is connected to the Internet (for example, open the website www.kaspersky.ru)
2. Set the proxy server settings in the product if you use a proxy server to access the Internet.
3. At the bottom right of the screen, right-click on the product icon and context menu select item Update.

   If the program icon is hidden from the notification area, click the button Show hidden icons. If the icon is missing,

The popular Kaspersky anti-virus reliably protects the system from various threats, but its successful operation requires constant updates. New viruses and others malware appear every day, and by missing 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 latest versions programs may be released 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 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 be that the key has expired, 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.
