4.2.2.1.1 Active mode for web browsers
ESET NOD32 Antivirus also contains the Active mode submenu, which defines the checking mode for web browsers.
Active mode is useful because it examines data transferred from applications accessing the Internet as a whole,
regardless of whether they are marked as web browsers or not (for more information, see Web and email clients). If
Active mode is disabled, communication from applications is monitored gradually in batches. This decreases the
effectiveness of the data verification process, but also provides higher compatibility for listed applications. If no
problems occur while using it, we recommend that you enable active mode by selecting the checkbox next to the
desired application.
This is how Active mode works: when a controlled application downloads data, it is first saved to a temporary file
created by ESET NOD32 Antivirus. Data is not available for the given application at that time. Once downloading is
complete, it is checked for malicious code. If no infiltration is found, data is sent to the original application. This process
provides complete control of the communications made by a controlled application. If passive mode is activated, data is
trickle-fed to the original application to avoid timeouts.
4.2.2.2 URL address management
The URL address management section enables you to specify HTTP addresses to block, allow or exclude from checking.
The Add, Edit, Remove and Export buttons are used to manage the lists of addresses. Websites in the list of blocked
addresses will not be accessible. Websites in the list of excluded addresses are accessed without being scanned for
malicious code. If you select the Allow access only to URL addresses in the list of allowed addresses option, only
addresses present in the list of allowed addresses will be accessible, while all other HTTP addresses will be blocked.
If you add a URL address to the List of addresses excluded from filtering, the address will be excluded from scanning.
You can also allow or block certain addresses by adding them to the List of allowed addresses or List of blocked
addresses. After you click the Lists... button, the HTTP address/mask lists window will pop-up where you can Add or
Remove lists of addresses. In order to add an HTTPS URL addresses to the list, Always scan SSL protocol must be
selected.
In all lists, the special symbols * (asterisk) and ? (question mark) can be used. The asterisk substitutes any character
string, and the question mark substitutes any symbol. Particular care should be taken when specifying excluded
addresses, because the list should only contain trusted and safe addresses. Similarly, it is necessary to ensure that the
symbols * and ? are used correctly in this list. To activate a list, select the List active option. If you wish to be notified
when entering an address from the current list, select Notify when applying address from the list.
Add.../From file – Allows you to add an address to the list, either manually (click Add), or from a simple text file (click
From file). The From file option enables you to add multiple URL addresses/masks saved in a text file.
Edit... – Manually edit addresses – e.g. by adding a mask ("*" and "?").
