In large LAN networks, communication between your computer and the internet can be mediated by a proxy server. Using this configuration, the following settings need to be defined. Otherwise the program will not be able to update itself automatically. In ESET NOD32 Antivirus, proxy server setup is available from two different sections of the Advanced setup tree.
First, proxy server settings can be configured in Advanced setup under Tools > Proxy server. Specifying the proxy server at this level defines global proxy server settings for all of ESET NOD32 Antivirus. Parameters here will be used by all modules that require a connection to the Internet.
To specify proxy server settings for this level, select Use proxy server and enter the address of the proxy server into the Proxy server field along with the Port number of the proxy server.
If communication with the proxy server requires authentication, select Proxy server requires authentication and enter a valid Username and Password into the respective fields. Click Detect to automatically detect and populate proxy server settings. The parameters specified in Internet Explorer will be copied.
Use direct connection if proxy is not available – If a product is configured to utilize HTTP Proxy and the proxy is unreachable, the product will bypass the proxy and communicate directly with ESET servers.
Proxy server settings can also be established from Advanced update setup (Advanced setup > Update > HTTP Proxy by selecting Connection through a proxy server from the Proxy mode drop-down menu). This setting applies for the given update profile and is recommended for laptops that often receive virus signature updates from remote locations. For more information about this setting, see Advanced update setup.
