Connection options

To access the proxy server setup options for a given update profile, click Update in the Advanced setup tree (F5) and then click Profiles > Updates > Connection options. Click the Proxy mode drop-down menu and select one of the three following options:

Do not use proxy server

Connection through a proxy server

Use global proxy server settings

Select Use global proxy server settings to use the proxy server configuration options already specified in the Tools > Proxy server branch of the Advanced setup tree.

Select Do not use proxy server to specify that no proxy server will be used to update ESET NOD32 Antivirus.

Connection through a proxy server option should be selected if:

A different proxy server than the one defined in Tools > Proxy server is used to update ESET NOD32 Antivirus. In this configuration, information for the new proxy should be specified under Proxy server address, communication Port (3128 by default), and Username and Password for the proxy server if required.

Proxy server settings are not set globally, but ESET NOD32 Antivirus will connect to a proxy server for updates.

Your computer is connected to the Internet via a proxy server. Settings are taken from Internet Explorer during program installation, but if they are changed (for example, if you change your ISP), please make sure the proxy settings listed in this window are correct. Otherwise the program will not be able to connect to update servers.

The default setting for the proxy server is Use global proxy server settings.

Use direct connection if proxy is not available – Proxy will be bypassed during update if it is unreachable.


The Username and Password fields in this section are specific to the proxy server. Complete these fields only if a username and password are required to access the proxy server. These fields should only be completed if you know you need a password to access the internet via a proxy server.
