Update

Updating databases and program modules of Kaspersky Anti-Virus ensures the up-to-date protection status to your computer. New viruses, Trojans, and other types of malware appear worldwide on a daily basis. Kaspersky Anti-Virus databases contain information about threats and ways of eliminating them so regular application update is required for ensuring your computer’s security and timely detecting new threats.

Regular update requires an active license for application usage. Without a license, you will only be able to update the application once.

Application update downloads and installs the following updates on your computer:

  • Kaspersky Anti-Virus databases.

    The protection of information is based on databases which contain signatures of threats and network attacks, and the methods used to fight them. Protection components use these databases to search for and disinfect dangerous objects on your computer. The databases are supplemented every hour with records of new threats. Therefore, you are advised to update them on a regular basis.

    In addition to the Kaspersky Anti-Virus databases, the network drivers that enable the application’s components to intercept network traffic are updated.

  • Application modules.

    In addition to the Kaspersky Anti-Virus databases, you can also update the program modules. The update packages fix Kaspersky Anti-Virus’s vulnerabilities, and supplement or improve the existing functionality.

The main update source of Kaspersky Anti-Virus are special Kaspersky Lab update servers. While updating Kaspersky Anti-Virus, you can copy database and program module updates received from Kaspersky Lab servers into a local folder, providing access to other networked computers. This saves Internet traffic.

You can also modify automatic update startup settings.

Your computer should be connected to the Internet for successful downloading of updates from our servers. By default, the Internet connection settings are determined automatically. If you use a proxy server, you may need to adjust the connection settings .

During an update, the application modules and databases on your computer are compared with the up-to-date version at the update source. If your current databases and modules differ from those in the actual version of the application, the lacking portion of updates will be installed on your computer.

If the databases are outdated, the update package may be large, which may cause additional Internet traffic (up to several dozen MB).

Prior to updating the databases, Kaspersky Anti-Virus creates backup copies of them if you want to roll back to the previous version of databases.

Information about the current condition of Kaspersky Anti-Virus databases is displayed in the Update section of the main application window.

Information on the update results and events, which have occurred during the execution of the update task, is logged in a Kaspersky Anti-Virus report.
