      %HomeDrive%\soS.Exe
      %HomeDrive%\Autorun.Inf
      %DriveLetter%\soS.Exe
      %DriveLetter%\Autorun.Inf
      %System32%\txomou.exe
      %System32%\autorun.inf
    (3)恢复病毒修改的注册表项目,删除病毒添加的注册表项:
      [HKEY_CURRENT_USER\Software
      \Microsoft\Windows\CurrentVersion
      \Explorer\Advanced]
      新建键值:DWORD:"Hidden"="0"
      原键值:DWORD:"Hidden"="1"
      [HKEY_CURRENT_USER\Software
      \Microsoft\Windows\CurrentVersion
      \Explorer\Advanced]
