(Symantec (Symantec) antivirus software, including SymantecAntiVirus or SAV series, SymantecClientSecurity or SCS series, and SymantecEndpointProtection or SEP series, are specially customized for enterprise users. These three sets of Symantec antivirus software include server-side installers and client-side installers, and are not sold to individual users. In the enterprise environment, by configuring the server side, each client is updated through the server side, and the server side communicates with Symantec through the network. Upgrade the server connection to update, because some clients in the enterprise cannot be updated because they cannot connect to the server due to some special factors, so Symantec allows the client to choose the independent installation mode when designing the program (that is, does not accept the server-side management mode. ), if the client chooses not to accept server-side management during installation, it can be updated directly from the Symantec server (the enterprise version does not require verification), because the client installer leaked by the enterprise is widely circulated, and because the enterprise version does not Verification is required, everyone uses this for free use. Now the commonly used enterprise antivirus software for individual users is the SEP11 series. Among these three models, SAV is a separate antivirus software without a firewall module; SCS is a suite of antivirus software and firewall, but only a simple combination; SEP is a seamless combination of antivirus software and firewall, and has an automatic protection module. In general, the Enterprise Edition is designed to provide enterprises with integrated anti-virus software, and provide powerful security protection for enterprise systems, especially server systems.)
