(Nota: %User Profile% es la carpeta de perfil del usuario activo, que en el caso de Windows 98 y ME suele estar en C:\Windows\Profiles\{nombre de usuario}, en el caso de Windows NT en C:\WINNT\Profiles\{nombre de usuario} y en el caso de Windows 2000, XP y Server 2003 en C:\Documents and Settings\{nombre de usuario}).
. %Windows% es la carpeta de Windows, que suele estar en C:\Windows o C:\WINNT).)Crea las siguientes copias de sí mismo en el sistema afectado:
- %User Profile%\Application Data\Java\?shimgvw?.exe
- %User Profile%\Application Data\Java\?Jview?.exe
(Nota: %User Profile% es la carpeta de perfil del usuario activo, que en el caso de Windows 98 y ME suele estar en C:\Windows\Profiles\{nombre de usuario}, en el caso de Windows NT en C:\WINNT\Profiles\{nombre de usuario} y en el caso de Windows 2000, XP y Server 2003 en C:\Documents and Settings\{nombre de usuario}).

Step 6
Buscar y eliminar estos archivos
- %User Profile%\Application Data\Java\Desktop.ini
- %Windows%\ntbtlog.txt
Step 7
Reinicie en modo normal y explore el equipo con su producto de Trend Micro para buscar los archivos identificados como WORM_NUQEL.DU En caso de que el producto de Trend Micro ya haya limpiado, eliminado o puesto en cuarentena los archivos detectados, no serán necesarios más pasos. Puede optar simplemente por eliminar los archivos en cuarentena. Consulte esta página de Base de conocimientos para obtener más información.
