x2y AV Ultimate

Real-Time Security & System Integrity for Windows

x2y AV Ultimate is a professional-grade security utility developed by x2y devs tools. It delivers genuine, non-AI, production-level system protection by utilizing a Hybrid Architecture (Flutter UI + Native Windows Service) to execute privileged system checks, real-time file monitoring, and advanced malware persistence analysis.

🌟 Features

1. Real-Time Protection Shield

• Active Monitoring: Runs in the background (System Tray) watching high-risk entry points (Downloads, Desktop, Documents).
• Instant Blocking: Intercepts file creation events, calculates SHA-256 hashes, and compares them against a local threat database.
• Kinetic Action: Automatically kills malicious processes and quarantines files before execution.

2. Intelligent Scanning Engine

• Quick Scan: Rapidly audits critical system areas (System32, User Root, Startup).
• Full Scan: Recursively traverses the entire file system with progress estimation.
• Custom Scan: Target specific files or folders for analysis.
• Smart Filtering: Uses exclusion zones to ignore trusted directories (configurable in Settings).

3. Network Activity Monitor

• Live Traffic Map: Visualization of active network flow using dynamic charts.
• Process Mapping: Maps every TCP/UDP connection to its specific Process ID (PID) using native netstat calls.
• Threat Intel: Flags suspicious connections or non-standard ports.

4. Persistence Auditor

• Registry Analysis: Scans HKCU and HKLM Run keys for hidden malware.
• Startup Folder: Audits physical startup directories for unauthorized scripts or binaries.

5. Quarantine Vault

• Secure Isolation: Threats are renamed to .x2y_quarantine and locked.
• Management: Users can Restore false positives or Permanently Delete threats.

🚀 Technologies Used

This application is built using Flutter for Windows with heavy reliance on FFI (Foreign Function Interface) for native system interactions.

• UI Framework: Flutter (Dart)
• Database Engine: SQLite (via sqflite_common_ffi) - Stores Scan History and Threat Definitions.
• Native Interop:
  • win32_registry: For reading Windows Registry keys.
  • process_run: For executing netstat and taskkill.
  • window_manager & system_tray: For background persistence and window control.
• Cryptography: crypto package for SHA-256 file hashing.

⚙️ Configuration

The app includes a robust Settings hub for customization:

• Run on Startup: Toggles Registry keys to automatically launch x2y AV Ultimate with Windows.
• Scheduled Scans: Set daily scan times, which are saved to local storage.
• Exclusions: Add specific file paths or directories to be ignored by the Real-Time Shield and scanning engine.
