hosts 文件是本機域名解析「總開關」,被惡意修改會導致無法上網、跳轉釣魚站、感染木馬。XP/Win7/Win8/Win10/Win11 位置統一:C:\Windows\System32\drivers\etc\hosts。兩種一鍵修復法:
# Copyright (c) 1993-2006 Microsoft Corp.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
hosts 文件小但關鍵,守住它,守住上網安全底線。
