How to install the application

Expand all | Collapse all

The application is installed to your computer in interactive mode using the Setup 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 the application 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 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.

2. Install additional applications

   When you install Kaspersky Plus or Kaspersky Premium, you can additionally install the following applications:

   • Kaspersky VPN Secure Connection, which enables Kaspersky VPN functionality using Virtual Private Network (VPN) technology.

   Kaspersky VPN functionality is not available in some regions.

   • Kaspersky Password Manager for protecting passwords.

   These applications are available only on Kaspersky Plus and Kaspersky Premium plans. If you want to use these applications, you can download and install them as separate applications. You can remove Kaspersky VPN Secure Connection or Kaspersky Password Manager without removing Kaspersky 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 the application 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 Continue (this button is called Accept in some regions).

   

   License Agreement acceptance window

   In some versions of the application, the End User License Agreement can be opened by clicking the link on the Wizard welcome screen. In this case, only the Back button is available on the window containing the text of the End User License Agreement. By clicking the Continue button, you accept the terms of the End User License Agreement.

   

   Window containing the text of the End User License Agreement

   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.

   Read the Kaspersky Security Network Statement and do one of the following:

   • If you accept all of its terms, click the Accept button.
   • If you do not want to participate in Kaspersky Security Network, click the Decline button.

     

     The Kaspersky Security Network Statement acceptance window

   In some application versions you need to select the I want to participate in Kaspersky Security Network and have read the KSN Statement check box on the welcome screen of the wizard to accept Kaspersky Security Network Statement. You can read the statement by clicking the KSN Statement link. After you read the statement, click the Back button to continue installation. If the I want to participate in Kaspersky Security Network and have read the KSN Statement check box is selected, you accept the terms of Kaspersky Security Network Statement by clicking the Continue button.

   

   Kaspersky Security Network Statement

   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.

3. 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

   The application 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. Applications that cannot be removed automatically must be manually removed by clicking the Remove manually button.

     

     Incompatible software removal window

   When removing incompatible applications, you will need to restart your operating system, after which installation of Kaspersky continues automatically.

4. 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 application, 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 application is run for the first time.

If you downloaded the application from your My Kaspersky account, after installation, the application is automatically activated with the subscription from your account.

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. 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 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 Kaspersky Plus, copies of files are kept and displayed automatically.

Kaspersky Protection browser extension

Expand all | Collapse all

In order for Kaspersky application to fully support browsers, the Kaspersky Protection extension must be installed and enabled in the browsers. The Kaspersky Protection extension injects 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. The application can embed the script without using the Kaspersky Protection extension.

The application 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.

When working with your browser, the Kaspersky Protection extension allows you to:

• Manage Private Browsing
• Manage Anti-Banner
• Safe Money

If the extension is installed together with Kaspersky Free, you will only have access to the following functions:

• Inform about suspected phishing

  To report a suspected phishing website:

  1. Make sure you are on the page that you suspect is a phishing page.
  2. In the toolbar of the browser, click Kaspersky Protection.

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

The application is removed using the Setup 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 the application, you must enter the password for accessing the application settings. If you cannot specify the password for any reason, application removal will be prohibited. After entering the password, click Confirm.

   

   Password entry window

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

2. Saving a subscription in your My Kaspersky account.

   At this step, you can specify whether you want to save the subscription in your My Kaspersky account for future use.

   

   Saving activation code window

   1. If you want to save a subscription, click the Save button.
   2. Click the Next > button.

   The window with the saved subscription will be displayed.

   

   Window with the saved subscription

   1. Click the Next > button.
3. 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).

   

   Saving settings window

   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 the application is removed from the computer, quarantined files become unavailable. To perform operations with these files, Kaspersky application 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).
     .
   • Secret Vault are files placed in storage using Secret Vault functionality.

   To continue uninstalling the application, click Next >.

How to update the application

The application is updated automatically if you select the Automatically update mode in the update settings window (Security → Anti-Virus Database Update → Databases update schedule).

The application is automatically updated if you install a new version of the application over the previous one. When you update paid versions of Kaspersky application, all your settings are preserved.

If the user has paused scanning tasks at the moment when the update arrives, the application will force these tasks to stop and will run the update. Active scanning tasks are not forced to stop.

While downloading the update, the application compares the previous and new versions of the End User License Agreement, Kaspersky Security Network Statement, and Statement regarding data processing for marketing purposes. If the texts of agreements and/or statements are not identical, the application prompts you to read and accept them again.
