Lưu ý:
- Phụ thuộc vào mạng đang sử dụng (VNPT, Viettel, FPT...), mỗi mạng khác nhau cần file HOST khác nhau mới có thể truy cập được Facebook.
- Việc thêm những thông số vào trong file host như nêu trên có thể bị các phần mềm diệt virus (như KIS, MSE... tự động xoá, dẫn đến không vào được facebook, do đó cần phải kiểm tra lại

Chúc các bạn thành công!
