Esque estos logs sirven para conocer rutas de algunos malwares conocidos y para que veas si en realidad estan las cosas que vos instalaste en tu pc, las que tendrian que estar. Lo que quiero decir es que tu mismo tendrias que saber que cosas tienes en tu pc, porque si nosotros vemos un programa muy conocido en el log, no diremos que es un malware, pero sin embargo talvez vos nunca lo instalaste entonces puede ser un malware.. Lo mejor que puedes hacer es formatear la pc y hacer un log de nuevo para saber que cosas tenes cuando recien comenzas desde 0 y luego vas a ir conociendo tu pc y un dia diras: "opa.. esto no tendria que estar corriendo en mi pc.." y ahi es cuando sirven estos logs de verdad.

Conclusion: Aprende a conocer tu pc y asi sabras cuando tienes algun bicho instalado. Saludos

Elimina la barra de searchqu, mas el proceso datamng asociado.

Para la barra de Searchqu, desinstalala desde el panel de control - Agregar o quitar programas (CCleaner tambien trae esa opción).
