How to install or remove the application

How to install the application

Kaspersky is installed to your computer in interactive mode using the Setup and Removal Wizard.

The Wizard consists of a series of windows (steps). The number and sequence of steps in the Wizard depend on the region where you install the application. In some regions, the Wizard prompts you to accept additional agreements regarding how your personal data is processed. To stop the Wizard's activity at any step of installation, close the Wizard window.

If the application will be used to protect more than one computer (with the maximum number of computers defined by the terms of the End User License Agreement), the installation procedure will be identical on all computers.

To install Kaspersky on your computer,

• If you are using an installation disk, insert the disk into the disk drive and follow the instructions on your screen.
• If you have downloaded the application from the Internet, launch it. The application is then installed using the standard Setup and Removal Wizard. In this case, the Wizard displays several additional installation steps for some localization languages.

You can also install the application from the command prompt.

The Setup Wizard goes through the following steps:

1. Starting installation

   During this step, the Wizard prompts you to install the application.

   Depending on the installation type and the localization language, during this step the Wizard may prompt you to view the End User License Agreement concluded between you and Kaspersky, and ask whether you want to participate in Kaspersky Security Network.

   Reviewing the End User License Agreement

   This step of the Wizard is displayed for some localization languages when installing Kaspersky downloaded from the Internet.

   During this step, the Wizard prompts you to review the End User License Agreement concluded between you and Kaspersky.

   Read the End User License Agreement thoroughly and, if you agree with all of its terms, click the Continue (this button is called Accept in some regions). Installation of the application to your computer then continues.

   If the terms of the End User License Agreement are not accepted, the application will not be installed.

   In some regions, you must also accept the terms of the Privacy Policy to continue installation of the application.

   Reviewing the Kaspersky Security Network Statement

   During this step, the Wizard invites you to participate in Kaspersky Security Network. Participation in the program involves sending information about threats detected on your computer, running applications, and downloaded signed applications, as well as information about your operating system, to AO Kaspersky Lab. No personal data received from you is collected, processed, or stored.

   Review the Kaspersky Security Network Statement. If you accept all of its terms, in the Wizard window, leave the check box selected and click Continue.

   If you do not want to participate in Kaspersky Security Network, clear the check box.

   After you accept or decline participation in Kaspersky Security Network, application installation continues.

   In some application versions, the Kaspersky Security Network Statement includes information about personal data processing.

2. Installing the application

   Installation of the application can take some time. Wait for it to finish. Upon installation completion, the Setup Wizard automatically proceeds to the next step.

   Checks during application installation

   Kaspersky performs several checks during installation. These checks may detect the following problems:

   • Non-compliance of the operating system with the software requirements. During installation the Wizard checks the following conditions:
     • Whether the operating system and Service Pack meet the software requirements;
     • All the required applications are available;
     • The amount of free disk space is enough for installation;
     • The user installing the application has administrator privileges.

     If any of the above-listed requirements is not met, a corresponding notification is displayed.

   • Presence of incompatible applications on the computer. If any incompatible applications are detected, they are displayed in a list on the screen, and you will be prompted to remove them. You are advised to manually remove any applications that Kaspersky cannot remove automatically. When removing incompatible applications, you will need to restart your operating system, after which installation of Kaspersky continues automatically.

   Installing Kaspersky Password Manager with the Kaspersky Plus application

   Before completing the installation, Kaspersky also prompts you to install Kaspersky Password Manager to protect your passwords. The installation of Kaspersky Password Manager may continue after finishing the installation of Kaspersky, there is no separate notification about completing the installation of Kaspersky Password Manager.

   The Kaspersky Password Manager application is not part of Kaspersky Basic and Kaspersky Standard plans. If you want to use the Kaspersky Password Manager application for password protection, you can download and install it as a separate application or switch to Kaspersky Plus.

3. Completing the installation

   During this step, the Wizard informs you of the completion of application installation.

   All necessary application components will be automatically started immediately after installation is complete.

   In some cases, you may need to restart your operating system to complete installation.

Along with the application, plug-ins for browsers are installed to ensure safe Internet browsing.

When you run audio and video recording or playback applications for the first time since installation of Kaspersky, audio and video playback or recording may be interrupted. This is required to enable the functionality that controls access by applications to sound recording devices. The system service that controls audio hardware is restarted when Kaspersky is run for the first time.

Kaspersky Plus is installed together with the Kaspersky VPN Secure Connection application intended for establishing a secure connection via Virtual Private Network (VPN). You can remove Kaspersky VPN Secure Connection separately from Kaspersky. If the use of VPN is prohibited in your country, Kaspersky VPN Secure Connection is not installed.

To continue using the application, you must connect to My Kaspersky and complete the activation process; for details, see the following sections:

Installing over other Kaspersky applications

The application can be installed over the following Kaspersky applications:

• Kaspersky Free
• Kaspersky Anti-Virus
• Kaspersky Internet Security
• Kaspersky Total Security
• Kaspersky Security Cloud

When you install the new application, previously installed Kaspersky Anti-Virus, Kaspersky Internet Security, Kaspersky Security Cloud, Kaspersky Total Security applications are removed. The license of a removed application can be used for the new Kaspersky application, with the exception of the Kaspersky Total Security license. The settings of removed applications are kept.

When you install the new application, the previously installed Kaspersky Free application is removed. The settings of Kaspersky Free are not saved.

When you switch from Kaspersky Total Security to Kaspersky Basic or Kaspersky Standard, backup copies of files are kept but not displayed in these applications. You can add backup copies of files manually. When you switch from Kaspersky Total Security to the Kaspersky Plus application, copies of files are kept and displayed automatically.

Getting started

In order for Kaspersky to fully support browsers, the Kaspersky Protection extension has to be installed and enabled in browsers. Kaspersky uses the Kaspersky Protection extension to embed a script into the web page opened in Protected Browser and into traffic. The application uses this script to interact with the web page and to transmit data to banks whose websites are protected by the Safe Money component. The application protects data transmitted by the script using a digital signature. Kaspersky can embed the script without using the Kaspersky Protection extension.

Kaspersky signs data transmitted by the script using the installed anti-virus databases and requests to Kaspersky Security Network. The application sends requests to Kaspersky Security Network regardless of whether or not you accepted the terms of the Kaspersky Security Network Statement.

Installing the Kaspersky Protection extension in Chromium-based Microsoft Edge, Mozilla Firefox, and Google Chrome

The Kaspersky Protection extension is not automatically installed in Chromium-based Microsoft Edge, Mozilla Firefox, and Google Chrome. If the Kaspersky Protection extension is not installed in the browser, the application prompts you to go to the extensions download page and manually install Kaspersky Protection when the browser is started.

Yandex Browser support

When using Yandex Browser, the following application components are operating:

• Protected Browser;
• URL Advisor
• Safe Browsing;
• Anti-Phishing.

The Private Browsing and Anti-Banner components operate but cannot be configured in Yandex Browser.

Internet Explorer support

Starting with Kaspersky 4, the Kaspersky Protection extension will no longer support the browser Internet Explorer. If you want to continue using the Kaspersky Protection extension in Internet Explorer, you can go back to the previous version of the application.

How to uninstall the application

After removing Kaspersky, your computer and personal data will be unprotected.

Kaspersky is removed using the Setup and Removal Wizard.

How to uninstall the application in Windows 7

How to uninstall the application in Windows 8 or later

Removal involves the following steps:

1. To remove Kaspersky, you must enter the password for accessing the application settings. If you cannot specify the password, for any reason, application removal will be prohibited.

   This step is available only if a password has been set for application removal.

2. Saving data for future use

   During this step you can specify which of the data used by the application you want to keep for further use during the next installation of the application (for example, when installing a newer version of the application).

You can save the following data:

• Subscription details is a set of data that rules out the need to activate the application during future installation, by allowing you to use it under the current subscription unless the subscription expires before you start the installation.
  • Quarantine files are files scanned by the application and moved to Quarantine.

    After Kaspersky is removed from the computer, quarantined files become unavailable. To perform operations with these files, Kaspersky must be installed.

  • Operational settings of the application are values of application settings selected when configuring the application.

  You can also export the protection settings at the command prompt, by using the following command: avp.com EXPORT <file_name>.

  • iChecker data are files that contain information about objects that have already been scanned using
    iChecker technology

    iChecker is a technology that increases the speed of anti-virus scans by excluding objects that have remained unchanged since their last scan, provided that the scan parameters (the anti-virus database and settings) have not changed. The information for each file is stored in a special database. This technology is used in both real-time protection and on-demand scan modes.

    For example, you have an archive file that was scanned by a Kaspersky application and assigned not infected status. Next time, the application will skip this archive unless the archive has been altered or the scan settings have been changed. If you altered the archive content by adding a new object to it, modified the scan settings, or updated the anti-virus database, the archive is re-scanned.

    Limitations of iChecker technology:

    • This technology does not work with large files, since it is faster to scan a file than to check whether the file has been modified since it was last scanned.
    • The technology supports a limited number of formats (EXE, DLL, LNK, TTF, INF, SYS, COM, CHM, ZIP, RAR).
    .
  • Anti-Spam databases are databases with specimens of spam messages added by the user.
  • Secret Vault are files placed in storage using Secret Vault functionality.

1. Confirming removal

   Since removing the application threatens the security of your computer and personal data, you will be asked to confirm your intention to remove the application. To do this, click the Remove button.

2. Completing removal

During this step, the Wizard removes the application from your computer. Wait until removal is complete.

This functionality may be unavailable in some regions.

During removal of the application, you must restart your operating system. If you cancel an immediate restart, completion of the removal procedure is postponed until the operating system is restarted or the computer is turned off and then started up.
