By default, ESET NOD32 Antivirus is configured to monitor the HTTP protocol used by most Internet browsers.
HTTP Scanner setup
In Windows Vista and later, HTTP traffic is always monitored on all ports for all applications. In Windows XP, you can modify the Ports used by HTTP protocol in Advanced setup (F5) > Web and email > Web access protection > Web protocols. HTTP traffic is monitored on the specified ports for all applications, and on all ports for applications marked as Web and email clients.
HTTPS Scanner setup
ESET NOD32 Antivirus also supports HTTPS protocol checking. HTTPS communication uses an encrypted channel to transfer information between server and client. ESET NOD32 Antivirus checks communication utilizing the SSL (Secure Socket Layer), and TLS (Transport Layer Security) protocols. The program will only scan traffic on ports defined in Ports used by HTTPS protocol, regardless of operating system version.
Encrypted communication will be not scanned. To enable the scanning of encrypted communication and view the scanner setup, navigate to SSL/TLS in Advanced setup section, click Web and email > SSL/TLS and enable the Enable SSL/TLS protocol filtering option.
