前几天，机子中了Shell.exe病毒，怎么弄也无未法杀掉它，每次开机均会在system32下自动生成Shell.exe文件，瑞星也发现不了。还会通过U盘传播，弄得我几台电脑均中毒了，经个几天摸索，终于将此毒彻底干掉了，现将杀毒方法写出来，希望对有类似情况的兄弟们有所帮助，高手别笑哦！
中毒的几个典型征状是：
1. 让计算机无法显示隐藏文件
2. 每次开机，会在C:\windows\system32下自动生成Shell.exe和Shell.pci文件
3. 感染 C:\windows\system32下的spoolsv.exe文件，从而造成无法执行打印程序(无法看见打印机)
4.在C盘根目录下生成pass.dic文件
5. 当插入U盘时，会在U盘自动生成Shell.exe和Autorun.inf文件

杀毒方式一：瑞星杀毒
下载更新最新的瑞星杀毒软件，然后再全盘杀毒。如此做后，病毒会全部去除。但由于系统文件spoolsv.exe由于受病毒感染，也被瑞星杀掉了。仍然会无法执行打印程序。此时，如果仅仅将无毒的系统文件spoolsv.exe由复制过来，还是不行的，系统的print spooler服务程序注册信息已没有了，必须手工加入print spooler服务程序注册信息，将以下内容保存为 1.reg 文件，然后双击该文件，将此信息加入注册表。

然后，再手工启动：Print spooler服务便可(“控制面板”—“管理工具”—“服务”里去启动“print spooler”)。

Shell病毒清除方式二：手工杀毒：
由于中毒后，用计算机自带的资源管理器无法查看隐藏文件，所以必须用一个可以查看并能删除隐藏文件的工具, 将system32下的spoolsv.exe文件和Shell文件均删掉(删掉之前，先中止Shell.exe进程)，硬盘根目录下可能有1.exe或2.exe病毒文件，同时也要清除(我是自编的一个工具).
然后将无毒的spoolsv.exe文件复制到system32目录下,重启计算机后，病毒不会再有了，同时打印功能也会自动恢复。这种方式更为简单,一分钟搞定.
