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 上面这个是我xp安全的hosts档 基本上 没这个档 并不会对电脑造成太大伤害 如果本身有中毒 那自己又没有hosts档的话 通常病毒会自动产生 而那里面的档案 并不会有上面的东西 只会有一堆防毒网站等 就像 127.0.0.1 www.symantec.com 127.0.0.1代表的是一个找不到的网址 举个例子来说 你在内部输入127.0.0.1 tw.yahoo.com 然後你在ie中 位址栏输入tw.yahoo.com 然後 它会自动指向127.0.0.1的位址 因此这样就会出现找不到此网页 病毒就是这样让你上不了防毒网站的 简单的说 前面的ip位址 就是让你後面的网址指向前面的ip --
