SOLUTION
Step 1
Los usuarios de Windows ME y XP, antes de llevar a cabo cualquier exploración, deben comprobar que tienen desactivada la opción Restaurar sistema para permitir la exploración completa del equipo.
Step 2
Reiniciar en modo seguro
Step 3

- In HKEY_CURRENT_USER\Identities
- From: Identity Ordinal = "2"
To: Identity Ordinal = ""1""
- From: Identity Ordinal = "2"
Step 6
Buscar y eliminar estos archivos
- %User Profile%\Application Data\Peol
- %User Profile%\Peol\awytu.exe
- %Application Data%\gozym.xyi
- %User Profile%\Address Book\Wilbert.wab
Step 7
Buscar y eliminar estas carpetas
- %User Profile%\Application Data\Peol
- %User Profile%\Microsoft\Address Book
Step 8
Reinicie en modo normal y explore el equipo con su producto de Trend Micro para buscar los archivos identificados como TSPY_ZBOT.LMI 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.
