Centrally Controlled Update 

12.1 Update Levels 

AVG Anti Virus offers three update levels to select from: 

Priority update 

The priority update contains changes necessary for a reliable anti virus protection. Typically, it 

does not include any changes to the code and updates only the virus definition database. This 

update should be applied as soon as it is available. 

Recommended update 

The recommended update contains various program changes, fixes and improvements. 

For mission critical systems, it is recommended that such updates are not applied automatically 

when they become available, but rather that they are tested in a testing environment first.  

Optional update 

The optional update reflects changes that are not necessary for program functionality   texts, 

updates of the setup component, etc. Optional updates can be downloaded and applied together 

with recommended updates but their importance is rather low. 

When scheduling an update, it is possible to select which priority level should be downloaded and applied. 

Every update of higher extent (e.g. Optional update) automatically includes all available critical updates 

(Priority update). 

12.2 Update within the Local Network 

AVG clients can perform an update directly from GRISOFT web servers. Also, it is possible to download 

the update file onto a LAN server, and configure the AVG clients for local update.  

For smaller networks (20 25 workstations typically) it is recommended to update directly from the 

Internet. AVG Anti Virus update files are designed so that the smallest available needed files are always 

being downloaded.  

If the network consists of more than 50 workstations, 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 

Anti Virus versions update) must be downloaded this way to allow AVG clients 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 local 

web server. AVG TCP Server provides limited web server functionality, and it can be used for mirroring. 

Update files can be downloaded on the AVG TCP Server using the AVGINET Lite application (a part of 

the AVGADMIN installation package). AVG clients then search for the update files on the computer with 

the AVG TCP Server running. This option is considered the preferred way of update file distribution within 

the local network. 

Note: 

For further information on AVG TCP Server settings please refer to chapter 

6.2   AVG TCP Server as a 

Local Web Server Update Source

.  

However, it is possible to use any other web server for this kind of update. The server only has to share 

one isolated folder accessible by AVG clients. When you are using Microsoft Information Server for 

example, the root of all the accessible folders is usually C:\InetPub\wwwroot. Supposing 

C:\InetPub\wwwroot\avgupdate folder, which is accessible by web interface, is present on the web 

server called localweb. Web (HTTP) clients can access documents and files in this directory by the URL 

http://localweb/avgupdate

. Following these steps, AVG clients will use the same URL 

http://localweb/avgupdate

 for updates.
