Netzwerk
Dieser Artikel behandelt AdGuard für Windows, einem multifunktionalen Werbeblocker, der Ihr Gerät auf Systemebene schützt. Um zu sehen, wie es funktioniert, laden Sie die AdGuard-App herunter
Das Modul Netzwerk ist der Netzwerkfilterung gewidmet, und hier finden Sie zusätzliche netzwerkbezogene Optionen. Zwei davon sind standardmäßig aktiviert: Datenverkehrsfilterung aktivieren und HTTPS filtern. Dies sind wichtige zusätzliche Vorsichtsmaßnahmen, um Ihren Webspace besser zu filtern. Die meisten Websites verwenden jetzt HTTPS, und dies gilt auch für die Werbung. Von vielen Websites, wie youtube.com, facebook.com und x.com, ist es unmöglich, Werbung ohne HTTPS-Filterung zu entfernen. Lassen Sie also die Funktion HTTPS filtern aktiviert, es sei denn, Sie haben einen triftigen Grund, dies nicht zu tun.
In diesem Modul können Sie das Kontrollkästchen AdGuard als HTTP-Proxy verwenden aktivieren, um AdGuard als regulären HTTP-Proxy zu verwenden, der den gesamten Datenverkehr filtert, der ihn durchläuft. Sie können auch die Funktion Websites mit EV-Zertifikaten filtern aktivieren. Extended Validation (EV) SSL-Zertifikate bieten eine stärkere Sicherheitsgarantie; die Inhaber solcher Websites müssen ein gründliches und weltweit standardisiertes Identitätsprüfungsverfahren durchlaufen, das durch EV-Richtlinien definiert ist. Daher werden Websites mit solchen Zertifikaten vertraut und nicht gefiltert.
Schließlich gibt es noch einen Abschnitt mit Proxy-Einstellungen. Dort können Sie angeben, welchen Proxyserver AdGuard verwenden soll, um Filter zu aktualisieren, neue Versionen zu erhalten usw.
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The TDI driver is also available, but it is outdated and may cause filtering issues in some versions of Google Chrome.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)
