Kaspersky is not updating
If your network contains more than 300 managed devices in a single network segment or if your network consists of several network segments with more than 9 managed devices in each network segment, we recommend that you use distribution points to propagate the updates to the managed devices (see figure below).
Distribution points reduce the load on the Administration Server and optimize traffic between the Administration Server and the managed devices.
You can calculate the number and configuration of distribution points required for your network.
In this scheme, the updates are automatically downloaded from the Administration Server repository to the repositories of the distribution points.
It is essential to update antivirus databases on a regular basis.
If you do not do this, your antivirus program will not detect new malicious programs.
From August 1, 2012 Kaspersky Lab stops releasing anti-virus databases in zip-archives.
Each Kaspersky Lab application requests required updates from Administration Server.
Using the Download updates to the Administration Server repository task In this scheme, Kaspersky Security Center downloads updates through the Download updates to the Administration Server repository task.
In small networks that contain less than 300 managed devices in a single network segment or less than 10 managed devices in each network segment, the updates are distributed to the managed devices directly from the Administration Server repository (see figure below).
Updating by using the Download updates to the Administration Server repository task without distribution points By default, the Administration Server communicates with Kaspersky Lab update servers and downloads updates by using the HTTPS protocol.
You can configure the Administration Server to use the HTTP protocol instead of HTTPS.
