We recommend ESET NOD32 Antivirus for use on a network server. ESET Smart Security also offers a personal firewall, antivirus, to prevent unsolicited communications from remote computers. While this is one of the advantages of ESET Smart Security provides home users, it can be to the detriment of the business and the environment, the computer network on a regular basis trying to communicate remotely with the server. ESET clearly hampers the server equipment ESET Smart Security (ESET, and customer service in North America does not support these institutions), as ESET personal firewall may be blocking access to the server, even if the administrator wants to change the server after installation.
