13. Updates
13.1. General Information
AVG offers two update levels to select from:
Definitions update contains changes necessary for reliable anti-virus, anti-spam and anti-
malware protection. Typically, it does not include any changes to the code and updates only
the definition database. This update should be applied as soon as it is available.
Program update contains various program changes, fixes and improvements.
When scheduling an update, it is possible to select which priority level should be downloaded and
applied.
You can distinguish between two types of update:
On demand update is an immediate AVG update that can be performed any time the need
arises.
Scheduled update - within AVG it is also possible to pre-set an update plan. The planned
update is then performed periodically according to the setup configuration. Whenever new
update files are present on the specified location, they are downloaded either directly from the
Internet, or from the network directory. When no newer updates are available, nothing
happens.
Note: If a time coincidence of a scheduled program update and scheduled scan occurs, the update
process is of higher priority and the scan will get interrupted.
13.2. Update within the Local Network
AVG stations can perform an update directly from the AVG Technologies web servers. Also, it is
possible to download the update file onto a LAN server, and configure the AVG stations for local
update.
For smaller networks (20-25 stations typically) it is recommended to update directly from the
internet. AVG update files are designed so that always the smallest available required files are
downloaded.
If the network consists of more than 50 stations, it is better to maintain mirroring of all the available
update files within the local network. All the update files (that could be used for all the previous AVG
versions update) must be downloaded this way to allow AVG stations to use the current file to
perform the program/virus database update.
Generally, there are two options of update files local mirroring. The recommended option is using the
UpdateProxy role, that can be deployed also on multiple servers. See the Deploying multiple
UpdateProxy roles chapter for more information.
By using this, the AVG Admin Server is able to automatically download all necessary update files.
