# Copyright (c) 1993-1999 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost 上面這個是我xp安全的hosts檔 基本上 沒這個檔 並不會對電腦造成太大傷害 如果本身有中毒 那自己又沒有hosts檔的話 通常病毒會自動產生 而那裡面的檔案 並不會有上面的東西 只會有一堆防毒網站等 就像 127.0.0.1 www.symantec.com 127.0.0.1代表的是一個找不到的網址 舉個例子來說 你在內部輸入127.0.0.1 tw.yahoo.com 然後你在ie中 位址欄輸入tw.yahoo.com 然後 它會自動指向127.0.0.1的位址 因此這樣就會出現找不到此網頁 病毒就是這樣讓你上不了防毒網站的 簡單的說 前面的ip位址 就是讓你後面的網址指向前面的ip --
