Rede
Este artigo aborda o AdGuard para Windows, um bloqueador de anúncios multifuncional que protege seu dispositivo a nível de sistema. Para ver como funciona, baixe o aplicativo AdGuard
O módulo Rede é dedicado à filtragem de rede, e aqui você encontrará opções adicionais relacionadas à rede. Dois deles estão habilitados por padrão: Habilitar filtragem de tráfego e Filtrar HTTPS. Estas são precauções extras importantes para filtrar melhor o seu espaço web. A maioria dos sites agora usa HTTPS, e o mesmo se aplica à publicidade. Em muitos sites, como youtube.com, facebook.com e x.com, é impossível excluir anúncios sem Filtragem HTTPS. Portanto, mantenha o recurso Filtrar HTTPS ativado, a menos que você tenha um bom motivo para não fazê-lo.
Neste módulo você pode selecionar a caixa de verificação Usar AdGuard como proxy HTTP para usar o AdGuard como um proxy HTTP regular que filtrará todo o tráfego que passa por ele. Você também pode ativar o recurso Filtrar sites com certificados EV. Os certificados SSL de validação estendida (EV) oferecem uma garantia de segurança mais forte; os proprietários de tais sites devem passar por um processo de verificação de identidade completo e padronizado globalmente, definido pelas diretrizes de EV. É por isso que alguns usuários confiam em sites com esses certificados e preferem não filtrá-los.
Por fim, há uma seção com configurações de proxy. Lá você pode especificar qual servidor proxy o AdGuard deve usar para atualizar filtros, obter novas versões e assim por diante.
SockFilter and other network drivers
In Network, you can also enable traffic filtering and choose which driver to use: SockFilter, WFP, or TDI.
WFP (Windows Filtering Platform) is a powerful driver, but it may present stability risks, such as occasional system crashes (BSOD) for some users.
The TDI driver is also available, but it is outdated and may cause filtering issues in some versions of Google Chrome. A temporary workaround exists, but it’s not a reliable long-term solution.
SockFilter is an experimental, lightweight kernel-mode network driver that works at the socket level (TCP/UDP). Instead of inspecting or modifying packets as they travel through the full Windows networking stack, a sock filter intercepts socket calls (e.g., connect, send, receive, bind) at a higher, more stable abstraction level. This makes it ideal for applications that need to monitor or control network activity without deep packet processing.
Currently, SockFilter Right is still unstable, and you may encounter bugs. When fully tested and implemented, SockFilter has the potential to bring several advantages over other drivers:
- It operates at a higher, socket-level layer: SockFilter works with socket operations rather than raw packets, making it less complex and more stable than WFP's low-level packet filtering.
- No interference with other network drivers: Because it sits above VPN, firewall, and antivirus WFP filters, it avoids filter-ordering problems and compatibility conflicts common in the WFP stack.
- Greatly reduced risk of NETIO-related BSODs: SockFilter doesn't run inside the NETIO packet pipeline, so it avoids the typical crash scenarios caused by WFP callouts mishandling buffers, classification results, or packet memory.
When it comes to disadvantages, SockFilter driver sees only socket-level operations and does not capture traffic generated by other kernel drivers or components that bypass the standard Winsock API. From a low-level networking perspective, this can be viewed as a limitation, since the driver cannot access raw packets or inspect non-socket traffic. However, for an ad-blocking application, this behavior is not just acceptable but optimal. All relevant traffic from browsers and user-mode applications goes through standard sockets, and that's exactly what we need to control. At the same time, ignoring low-level driver traffic removes unnecessary complexity, avoids compatibility issues, and keeps the system stable.
AdGuard VPN
The last section is dedicated to AdGuard VPN — an ideal tool that provides security and anonymity each time you browse the Internet. You can download it by clicking the Download button or go to the AdGuard VPN website by clicking the Homepage button.
How does AdGuard VPN work? Without going into technical details, we can say that VPN creates a secure encrypted tunnel between the user's computer or mobile device and a remote VPN server. In this way, data privacy is preserved, as well as the anonymity of the user, because a third-party observer sees the IP address of the VPN server and not the actual user's IP.
What AdGuard VPN does:
- hides your real whereabouts and helps you stay anonymous
- changes your IP address to protect your data from tracking
- encrypts your traffic to make it unreadable to third parties
- lets you configure where to use VPN and where not to (exclusions feature)
