Hola, te doy la bienvenida al foro, sigue estos pasos:

- Descarga la herramienta DelPSGuard.zip y ejecútala en Modo a Seguro

- Descarga el Super Antispyware instálalo y actualízalo luego realiza un escaneo en Modo Seguro

- Pasa el Ccleaner y siguiendo los pasos de su manual utiliza las opciones Limpiador y Registro.

- Reinicia la máquina y realiza un escaneo con Ewido Online, luego pega otro log de Hijackthis y uno de DelPSGuard nos cuentas como te fue.

Saludos
