Unlike ESET Nod 32 Smart Security antivirus Kaspersky is updated only with a valid license and an active connection to the Internet. If the user has not had access to the Internet for a long time, the anti-virus databases become outdated and the system may be at risk. Therefore, you should update your antivirus regularly. There are several ways to do this: automatic updating and manual.

Automatic update of Kaspersky antivirus?

In order to start automatic updating of Kaspersky anti-virus databases, you should perform a number of simple steps:

• Right-click on the antivirus icon in the lower right corner of the screen and select “Update”.

• Or you can double click Open the main program window and click “Update”.

• A new window will open. It will display the database update process.

It is worth noting that during the update, not only anti-virus databases are loaded, but also software modules that eliminate the product’s vulnerability to new viruses and potentially dangerous applications.

Manual update of Kaspersky without connecting to the network

Many users believe that simply copying the latest Kaspersky databases from another computer can help update the databases and program modules. However, this method does not work.

The developers of the antivirus itself have released a special program for their users who are not able to update the program via the network - Kaspersky Update Utility. This utility allows you to update your antivirus without connecting via local network. It works as follows.

• Download the archive. Unpack the files into separate folder. You don't have to unpack it, but run the file via Total Commander.

• Run UpdateUtility-Gui.exe.

• A window will open. Click on the “Programs” button.

• A list of products will appear. Select your antivirus version. Click "OK".

• In the next window, click on the “Options” button.

• About the new window, you need to go to the “Download” section and select the folder into which the updates will be downloaded and the temporary folder. Click "OK".
• After specifying the location where you should download the updated antivirus databases, click the “Run” button.

• After the databases are downloaded, a subfolder called “Updates” will appear in the folder.
• Now copy this subfolder and transfer it to the flash drive. We connect it to a PC that does not have an update and specify the path to this folder in the antivirus settings.

• Then click “Update”. The antivirus will update the databases and modules. PC protection will be guaranteed.

You can see how to update your antivirus in the video from the program developers:

According to statistics, new varieties malware occur daily. And even more often! It is quite possible that at the very moment when you read these lines, the the new kind malware. We will not give an assessment to the individuals who turned the storehouse of human wisdom into a potentially dangerous place - we will leave that to psychologists.

Be that as it may, currently connecting to without antivirus program do not do it.

Computer software protection

As you know, where demand arises, supply does not take long to appear. Many companies offer various solutions to protect data from computer viruses. Some of them are very successful, such as software products from Kaspersky Lab, NOD32 from Eset, etc. These solutions are deservedly popular among users. Currently, complex software systems- the so-called “Internet Security” group. They are in the line of every manufacturer, although they may have different names. For example, for Dr.Web it is Security Space, and for NOD32 it is Smart Security. However, protection works properly only if the program has the ability to update itself - to receive updated versions of its own files and virus databases from some source. Otherwise, a situation may arise when new malicious code turns out to be invisible to antivirus detection algorithms. Since the topic is too broad, today we will look at why Kaspersky Anti-Virus is not updated.

Little-known nuances

If Kaspersky is not updated, do not panic - it will always be done in time. Usually the reason can be easily resolved even without contacting customer support. Well, we recommend rolling up your sleeves and... first, carefully read what to do if Kaspersky is not updated.

One of the reasons is the action of a virus that made changes to the system In Windows, you can access it by following the path c:\Windows\System32\drivers\etc\. By making changes to its structure (edited with notepad), you can redefine the addresses of Internet resources or block access to antivirus servers. Result - Kaspersky is not updated. We recommend that you familiarize yourself with the normal content of hosts (available, for example, on Wikipedia) and edit it if necessary.

Next possible reason, due to which Kaspersky is not updated, this is an unstable connection to the Internet.

In this case, the process is simply interrupted at some stage (for example, upon reaching 70%). The solution is simple: you should re-enable the update. It is also worth noting that sometimes the indicator freezes at 99% and nothing happens for a long time (sometimes up to five minutes). In this case, you should wait a little longer.

If Kaspersky is not updated, it is quite possible that the settings indicate working through a proxy. It is necessary to click the “Proxy server” button in the update source settings and enter the correct data (if any) or disable this mechanism(if not used).

Another common reason is that the key has expired. This antivirus is not updated.

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

After installing KIS, I activated the product by entering the 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 wondered: 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.

If you are also having problems with automatic Kaspersky update Antivirus or Kaspersky Internet Security, you can try the following solutions.

It is also worth checking that your computer is connected to the Internet and that you have not blocked Kaspersky in any way.

Make sure your system date and time are correct

Before you begin troubleshooting, make sure that your system date and time are correct, as Kaspersky depends on your system date and time to load the virus database.

Teach Kaspersky to automatically download updates

It is very important. With default settings, Kaspersky products regularly connect to the server and automatically download available updates. But if you have changed this default setting, you need to set it to automatic download updates by following the instructions below:

1. Launch Kaspersky. To do this, double-click the “Kaspersky” icon on the taskbar or notification area.
2. Click on the small option Settings located in the lower right corner to open Kaspersky settings.
3. In the left panel, click " Additionally" to view the different options on the right side. Now click Update Options on the right to go to the Update Options page.
4. here make sure the first option is selected Loading and install updates automatically, and if not, select the same to automatically download and install updates.
5. Then click " Configure the update launch mode", set it to Automatic and click the "Save" button. Ready!

Enable update tasks when running on battery

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.
3. Right remove checkbox“Disable scheduled scanning tasks” when running on battery power. Ready!

Configure Kaspersky to not use a proxy server

For users who need to connect to the Internet using a proxy server, Kaspersky offers options for using a specific proxy server. If you are not connecting to the network using a proxy server, make sure that the "Don't use a proxy server" option is enabled by following the instructions below.

These are the main reasons why Kaspersky is not updated. We hope the article was useful to you. Tell us about it in the comments!

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 on its website special utility, which will completely remove the antivirus from the 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, with 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: search the Internet for content original file"hosts" (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.

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.

If the database is not updated in a timely manner, the antivirus may not detect virus program, which 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 .

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 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.

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.

• 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.

It is also worth checking that your computer is connected to the Internet and that you have not blocked Kaspersky in any way.

Make sure your system date and time are correct

Before you begin troubleshooting, make sure that your system date and time are correct, as Kaspersky depends on your system date and time to load the virus database.

5. Then click " Configure the update launch mode", set it to Automatic and click the "Save" button. Ready!

Enable update tasks when running on battery

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.

Computer software protection

As you know, where demand arises, supply does not take long to appear. Many companies offer various solutions to protect data from computer viruses. Some of them are very successful, such as software products from Kaspersky Lab, NOD32 from Eset, etc. These solutions are deservedly popular among users. Currently, complex software systems are especially relevant - the so-called “Internet Security” group. They are in the line of every manufacturer, although they may have different names. For example, for Dr.Web it is Security Space, and for NOD32 it is Smart Security. However, protection works properly only if the program has the ability to update itself - to receive updated versions of its own files and virus databases from some source. Otherwise, a situation may arise when new malicious code turns out to be invisible to antivirus detection algorithms. Since the topic is too broad, today we will look at why Kaspersky Anti-Virus is not updated.

By making changes to its structure (edited with notepad), you can redefine the addresses of Internet resources or block access to antivirus servers. Result - Kaspersky is not updated. We recommend that you familiarize yourself with the normal content of hosts (available, for example, on Wikipedia) and edit it if necessary.

The next possible reason why Kaspersky is not updated is an unstable Internet connection.

In this case, the process is simply interrupted at some stage (for example, upon reaching 70%). The solution is simple: you should re-enable the update. It is also worth noting that sometimes the indicator freezes at 99% and nothing happens for a long time (sometimes up to five minutes). In this case, you should wait a little longer.

If Kaspersky is not updated, it is quite possible that the settings indicate working through a proxy. It is necessary to click the “Proxy server” button in the update source settings and enter the correct data (if there is one) or disable this mechanism (if not used).

Another common reason is that the key has expired. This antivirus is not updated.
