4.2.2 Web access protection
Internet connectivity is a standard feature in a personal computer. Unfortunately, it has also become the main medium
for transferring malicious code. Web access protection works by monitoring communication between web browsers
and remote servers, and complies with HTTP (Hypertext Transfer Protocol) and HTTPS (encrypted communication)
rules.
We strongly recommend that Web access protection is enabled. This option can be accessed from the main window of
ESET NOD32 Antivirus by navigating to Setup > Web and email > Web access protection. Access to known web
pages with malicious content is always blocked.
4.2.2.1 HTTP, HTTPs
By default, ESET NOD32 Antivirus is configured to use the standards of most Internet browsers. However, the HTTP
scanner setup options can be modified in Advanced setup (F5) > Web and email > Web access protection > HTTP,
HTTPS. In the main HTTP/HTTPS scanner window, you can select or deselect the Enable HTTP checking option. You
can also define the port numbers used for HTTP communication. By default, the port numbers 80 (HTTP), 8080 and
3128 (for Proxy server) are predefined.
ESET NOD32 Antivirus supports HTTPS protocol checking. HTTPS communication uses an encrypted channel to
transfer information between server and client. ESET NOD32 Antivirus checks communications utilizing the SSL (Secure
Socket Layer), and TLS (Transport Layer Security) encryption methods. HTTPS checking can be performed in the
following modes:
Do not use HTTPS protocol checking – Encrypted communication will not be checked.
Use HTTPS protocol checking for selected ports – HTTPS checking only for ports defined in Ports used by HTTPS
protocol.
Use HTTPS protocol checking for selected ports – The program will only check those applications that are specified in
the browsers section and that use ports defined in Ports used by HTTPS protocol. Port 443 is set by default.
Encrypted communication will be not scanned. To enable the scanning of encrypted communication and view the
scanner setup, navigate to SSL protocol checking in Advanced setup section, click Web and email > Protocol filtering
> SSL and enable the Always scan SSL protocol option.
