前段时间两位可怜姐姐的电脑都被病毒袭击了，那惨样。

         不提了，现在进入正题。
         首先：“开始”——“运行”输入“net stop server”然后回车，如果提示有其他服务一并关闭，直接输入“y”然后回车。

          然后把下面的内容：

          上面的代码能够一定程度抵御病毒和木马的袭击，看得懂的自己研究，我不解释。

          将代码复制到记事本中，存为批处理文件（就是后缀名bat），然后运行保存的文件就OK了。

          最后安装几个常用的安全软件，

           奇虎360安全卫士       下载

            谷歌工具栏                下载

           谷歌工具栏不用介绍，奇虎安全卫士的操作如下：

            1.查杀木马。

                        

          2.清理恶意插件。

                         

           3.修补系统漏洞。

                        

            3.开启实时保护。

                         

         

最后给大家推荐两个观察进程的安全工具：Process Explorer （这个有汉化版，随处可见） 

                                                                   IceSword             （安全焦点有下载）

最后奉劝大家不要用什么杀毒软件，装杀软，浪费不少硬件资源，简直费神。我最反感那东西。自己搞搞研究，做个免杀还不错，普通用户没那必要，
