URL address management

The URL address management section allows you to specify HTTP addresses to block, allow or exclude from checking.

Websites in the List of blocked addresses will not be accessible unless they are also included in the List of allowed addresses. Websites in the List of addresses excluded from checking are not scanned for malicious code when accessed.

Enable SSL protocol filtering must be selected if you want to filter HTTPS addresses in addition to HTTP web pages. Otherwise only the domains of HTTPS sites that you have visited will be added, the full URL will not be.

In all lists, the special symbols * (asterisk) and ? (question mark) can be used. The asterisk represents any number or character, while the question mark represents any one character. 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. See Add HTTP address / domain mask for how a whole domain including all subdomains can be matched safely. To activate a list, enable the List active option. If you want to be notified when entering an address from the current list, enable Notify when applying.

If you want to block all HTTP addresses except addresses present in the active List of allowed addresses, add * to the active List of blocked addresses.

Add – Creates a new list in addition to the predefined ones. This can be useful if you want to logically split different groups of addresses. For example, one list of blocked addresses may contain addresses from some external public blacklist, and a second one may contain your own blacklist, which makes it easier to update the external list while keeping yours intact.

Edit – Modifies existing lists. Use this to add or remove addresses from the lists.

Remove – Deletes existing list. Only possible for lists created with Add, not for the default ones.
