UPDATING THE APPLICATION
Keeping protection up-to-date is a key to reliably protecting your computer. As new viruses, Trojans, and malicious
software emerge daily, it is extremely important to update the application regularly to keep your data permanently
protected.
Kaspersky Anti-Virus update implies that the following components will be downloaded and installed on your computer:
 Application databases
Protection of information stored on the computer is ensured thanks to databases. File Anti-Virus and virus scan
tasks use databases when they scan for dangerous objects on your computer and disinfect them. The
databases are hourly renewed with records of new threats and methods of fighting them. Therefore, it is
recommended to update them on a regular basis.
 Application modules
In addition to the databases, you can update the internal modules of Kaspersky Anti-Virus. Update packages are
regularly released by Kaspersky Lab.
Special Kaspersky Lab update servers are the primary update source for Kaspersky Anti-Virus.
Your computer should be connected to the Internet to successfully download updates from servers. If the Internet
connection is ensured by a proxy server, you will need to configure connection settings (see section "Configuring proxy
server settings" on page 69).
Updates can be downloaded in one of the following modes:
 Automatically. Kaspersky Anti-Virus checks for an update package in the update source at time intervals you
have set. During virus outbreaks, the check frequency may increase, and decrease when they are gone. If
Kaspersky Anti-Virus detects new updates, it downloads and installs them on the computer. This is the default
mode.
 By schedule. Kaspersky Anti-Virus is updated according to a specified schedule.
 Manually. You launch the updating procedure manually.
When the update is in progress, the application modules and databases on your computer are compared against those at
the update source. If your computer has the most recent version of databases and application modules installed, you will
see a message confirming that the protection of your computer is up-to-date. If databases and modules on your computer
and those on the update server differ, the application downloads only the missing part of the updates. Databases and
modules are not downloaded in their entirety; this significantly increases the speed of updating and reduces Internet
traffic.
Before updating the application databases, Kaspersky Anti-Virus creates backup copies of them; these backup copies
can be used if you want to use them again for any reason. You might need the rollback (see section "Rolling back the
latest update" on page 62) option, for example, if you have updated the databases and they have been corrupted during
the operation. You can easily roll back to the previous version of databases and try to update them again.
You can distribute downloaded updates to a local source while updating Kaspersky Anti-Virus (see section "Update
distribution" on page 67). This feature enables you to update databases and modules used by the application on
networked computers to reduce internet traffic.
