Step 7

Buscar y eliminar estos archivos

[ learnMore ]
Puede que algunos de los archivos del componente estén ocultos. Asegúrese de que tiene activada la casilla Buscar archivos y carpetas ocultos en la opción "Más opciones avanzadas" para que el resultado de la búsqueda incluya todos los archivos y carpetas ocultos.
  • {Drive Letter}:\autorun.inf
  • %Program Files%\{Random filename}.inf
DATA_GENERIC_FILENAME_1
  • En la lista desplegable Buscar en, seleccione Mi PC y pulse Intro.
  • Una vez haya encontrado el archivo, selecciónelo y, a continuación, pulse MAYÚS+SUPR para eliminarlo definitivamente.
  • Repita los pasos 2 a 4 con el resto de archivos:
      • {Drive Letter}:\autorun.inf
      • %Program Files%\{Random filename}.inf

    • Step 8

    Reinicie en modo normal y explore el equipo con su producto de Trend Micro para buscar los archivos identificados como TROJ_AGENT.UOU 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.
