AVG TCP Server 

AVG TCP Server is used to secure communication between the AVG Anti Virus clients on workstations, 

and the AVG DataCenter on the server. Through the AVG TCP Server the AVG Anti Virus clients connect 

to the AVG DataCenter using the TCP protocol (or the HTTP protocol, to be exact) that is a part of each 

Windows operating system installation. Therefore, the AVG Anti Virus clients do not need any other third 

party component to be able to connect to the remote administration system.

Besides this elementary function, the AVG TCP Server can also provide update distribution within the 

local network. AVG TCP Server can work as a very simple web server offering the update files to AVG 

Anti Virus clients. The update files are downloaded from the Grisoft central update servers just once, 

which significantly decreases the Internet connection link load, especially in larger networks. 

There is also a possibility of different remote network administration solution, e.g. using the SQL server 

and the ODBC driver, or with help of the Firebird database server, etc. These alternatives are described in 

detail in the 

7.8   Using a Different SQL Engine

 chapter. 

6.1 AVG TCP Server Installation and Launch 

By default, the AVG TCP Server is installed into the C:\Program Files\Grisoft\AVG TCP Server 

directory. If you select another destination folder for the network administration, the AVG TCP Server 

will be installed into the AVG TCP Server subdirectory within the selected directory. 

In the Windows NT4/2000/2003/XP Professional environment the AVG TCP Server launches 

automatically on operating system start up.  

In the Windows 98/Me environment the AVG TCP Server launch is defined by the register key record 

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices. 

6.2 AVG TCP Server as a Local Web Server Update Source 

Using the web server implemented into the AVG TCP Server it is possible to perform a centrally 

controlled AVG Anti Virus update within the local network.  

This option's main advantage consists of the fact that AVG Anti Virus clients on separate workstations do 

not have to download the update files from the Internet but can update from the local network update 

source. This way the connection load is significantly decreased, and the download time shortened. This 

function can be provided by any web server. AVG TCP Server secures the service if there is no local web 

server in the network.  

All workstations download their updates based on a preset schedule using the HTTP protocol. The web 

server (AVG TCP Server, or any other web server) address used for the local update can be specified 

directly on the workstation, in the AVG Control Center/Update manager 

component/Configuration/URL tab. If the workstation is connected to the network administration you 

can also control the updates within the 

AVGADMIN

 application. 

The easiest way to download the update files from the Internet to the local web server is using the 

AVGINET Lite

 application. 

The AVGINET Lite program is a part of the AVGADMIN installation. Automatically, it is able to mirror all 

update files, to remove all redundant files, and to download new ones. For this purpose, we recommend 

running AVGINET Lite with these parameters: 

AVGINETL.EXE /URL="http://www.grisoft.cz/softw/70/update" /DIR="C:\AVGUPDATE" 

/PRI=5 

The /DIR parameter must correspond to the AVG TCP Server configuration value, Local HTTP Server 

Root item!
