UPDATE
Keeping the application updated is a prerequisite for reliably protecting your computer. New viruses, Trojans, and
malicious software emerge daily, so it is important to update the application regularly to keep your personal data
constantly protected. Information about threats and methods of their neutralization is stored in the databases of
Kaspersky Anti-Virus, therefore their timely updating is an essential part in the maintenance of reliable protection.
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 added to 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 also updated.
Application modules.
In addition to the databases of Kaspersky Anti-Virus you can also update the program modules. The update
packages fix the application's vulnerabilities and add new or improve the existing functionality.
Kaspersky Lab's update servers are the primary update sources for Kaspersky Anti-Virus.
To successfully download updates from servers, your computer must be connected to the Internet. By default, the
Internet connection settings are determined automatically. If the proxy server settings are not determined automatically,
the connection settings can be edited manually.
During an update, the application modules and databases on your computer are compared with those at the update
source. If your computer has the latest version of the databases and application modules, you will see a notification
window confirming that your computer's protection is up to date. If the databases and modules on your computer differ
from those on the update server, the application downloads only the incremental part of the updates. The fact that not all
the databases and modules are downloaded significantly increases the speed of copying files and saves Internet traffic.
If the databases are outdated, the update package can be large and it can cause the additional internet traffic (up to
several tens of Mb).
Prior to updating the databases Kaspersky Anti-Virus creates a backup copies of them in case you may want to roll back
to the previous database version.
You might need the update rollback option if, for example, the databases have become corrupted during the update
process. You can easily roll back to the previous version and try to update the databases again.
You can copy the retrieved updates to a local source while updating Kaspersky Anti-Virus. This service allows updating
the databases and program modules on network computers to save Internet traffic.
You can also configure automatic update startup.
The My Update Center section of the main application window displays information about the current status of
Kaspersky Anti-Virus databases:
release date and time;
number of database records and their composition;
databases status (up to date, out of date or corrupted).
