==================================

启动项目中,多出了最后一个内容!兰色字体的哪个

c:\WINDOWS\system32\RavExt.dll是Worm.Brontok.ea病毒
1  、用DOS启动系统
2、删除：c:\winnt\kesenjansosial.exe
      c;\winnt\shellnew\rakyatkelaparan.exe
      c:\winnt\system32\ravext.dll
3、删除c:\winnt\system32\msicn\plugins 下所有.dll文件

4、删除：C:\Documents and Settings\Administrator\Local Settings\Application Data下所有病毒可执行文件

5、重启系统到win2000或winxp，用注册表修复工具（如瑞星注册表修复工具）恢复注册表，屏蔽无关启动项。问题得到解决。


操作时要小心,最好预先备份以下.

我是菜鸟!怎么启动DOS啊!详细点好吗
