- From: ShowUI = "0"
Step 5
Buscar y eliminar estos archivos
- %Windows%\Fonts\F5F520B0.DLL
- %Windows%\Fonts\1B7AFA40.EXE
Step 6
Explorar el equipo con su producto de Trend Micro para eliminar los archivos detectados como TROJ_DLOADER.UPH 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.
