C:\windows\system32\com Xóa hết các file có thuộc tính ẩn và sysem trong đó ( chủ yếu là 2 file lsass.exe và smss.exe)
xóa hết đi 

Đường dẫn này còn tùy vào version của virus. Con mà mình gặp nằm trong Windows\Fonts\
(Chạy hijackthis là thấy ngay thôi mà)

Cái này mình đã từng làm rùi Mình vào Dos show hết những File trong c:\windows\system32\com thì nó vẫn thấy File lsass.exe và smss.exe Nhưng khi thực hiện lệnh xoá thì lại báo ko tìm thấy file này.---> tại sao lại như thế chả lẽ trong Dos mà nó vẫn chạy sao 

File ẩn bạn phải xóa bằng: del filename /ah  

config.php
