1 - Web Ad Blocking

Basic Principles of Ad Blocking

“NullScreen” employs DNS filtering technology to monitor and analyze network requests in real-time. When detecting ad-related domain requests, the system automatically returns a null address or local loopback address, effectively blocking ad content loading. This method is both efficient and transparent to users, without affecting normal browsing experience.

Intelligent Blacklist System

NullPrivate adopts a multi-level blacklist management mechanism:

• Automatic Updates: The system regularly fetches the latest ad domain lists from trusted sources
• Category Management: Classifies domains into different categories such as ads, trackers, and malware
• Performance Optimization: Uses efficient matching algorithms to ensure quick responses
• Statistical Analysis: Provides detailed blocking statistics to help

2 - Mobile Ad Blocking

Problem Overview

Many Android devices ship with pre-installed adware that:

• Pops up ads at inappropriate moments
• Continuously collects user data in the background
• Consumes system resources, causing performance degradation
• Generates unnecessary network traffic
• Significantly shortens battery life

AdGuard Solution

“NingPing” protects your device by:

• Blocking network requests from adware
• Preventing malicious tracking
• Optimizing device performance
• Extending battery life
• Reducing mobile data usage

3 - Privacy Protection

The Relationship Between Privacy and Advertising

Advertisers’ revenue primarily comes from ad conversions. To improve conversion rates, platforms need to:

1. Increase user retention
2. Deliver personalized ads

This requires collecting vast amounts of user privacy data. Platforms circumvent legal restrictions through:

• Complex user agreements
• Data exchanges with partners
• Disguised data anonymization

Priority of Privacy Protection

Privacy protection is more important than mere ad blocking:

• AdGuard’s Chinese region tracking blocking rules (>400,000) far exceed ad rules (<100,000)
• Some platforms generate more revenue through privacy data despite having fewer ads

Behind Platforms’ “Thoughtfulness”

So-called personalized recommendations often don’t truly understand user needs, but rather serve as marketing strategies:

• “You might like this” actually means “We want to sell this”
• Seemingly thoughtful services mask continuous data collection

How to Protect Yourself

Learn “cyber discretion” – control privacy leaks to avoid accurate profiling by platforms. AdGuard Private Service can help you achieve this goal.

4 - Malware Blocking

What is Malware?

Malware is a category of software designed to damage or gain unauthorized access to computer systems. It may:

• Steal personal information and sensitive data
• Disrupt system functions and files
• Encrypt data for ransom
• Recruit devices into botnets

How Malware Spreads

Hackers typically spread malware through the following methods:

• Download links disguised as legitimate software
• Attachments in phishing emails
• Vulnerable websites
• Infected advertisements

How AdGuard Protects You

“NingPing” provides comprehensive malware protection:

• Blocks known malware download links
• Prevents communication between malware and command-and-control servers
• Identifies and stops suspicious data exfiltration
• Regularly updates malware signature databases

It is recommended that you also adopt additional security measures, such as keeping your system and software up to date and exercising caution when downloading and opening attachments.

5 - Adult Content Blocking

Feature Overview

“NullPrivate” employs a multi-layer content filtering mechanism that can effectively identify and block:

• Pornographic and adult content sites
• Violent content
• Gambling-related sites
• Other harmful information

How It Works

The system achieves content blocking through:

1. DNS-level blocking: Prevents domain resolution of known harmful sites
2. Intelligent categorization: Classification system based on multiple trusted data sources
3. Real-time updates: Regularly updated blocking rules to ensure protection effectiveness

Configuration Guide

Basic Settings

Add the blocklist Link to the filter blacklist

Advanced Options

• Custom rules: Add specific sites to the blocklist
• Exception management: Set up whitelists to avoid false positives
• Access logs: View blocking records

• Public spaces: Suitable for public networks in libraries, schools, etc.

Notes

1. Recommended to use in conjunction with anti-addiction features
2. Regularly check and update filtering rules
3. If false positives occur, promptly add to whitelist
4. If circumvention is detected, submit feedback

6 - Social Network Blocking

Risks of Social Network Tracking

Social network platforms collect user data through various means:

• Social plugins and share buttons

With these measures, you can continue using the core features of social networks while protecting yourself from unwanted tracking and data collection.

7 - Phishing Site Blocking

What is a phishing site?

A phishing site is a fraudulent website that masquerades as a legitimate one in order to obtain sensitive information such as personal details and account passwords. These sites usually imitate:

• Banks and payment platforms
• Social networks
• E-commerce sites
• Government agency websites

Main risks

• Stealing user accounts and passwords

8 - Tracking Protection

What is Tracking?

Tracking is the practice of websites and applications collecting user data. Common tracking methods include:
