Hola!!

Hice fix en als entradas que me recomendaste y eliminé tambien el archivo que me indicaste.
Enel karpersky me ha encontrado un trojano pero la verdad que no sé ni como se habrá instalado pq tengo el pc formateado hace solo una semana y solo uso el outlook, hotmail y el messenger (que supongo que se habra colado x ahi) y el problema de lentitud me pasa desde hace un año a pesar de formatear varias veces (incluso mientras instalo windows y hoy pasaba el kaspersky el pc hace beep beep beep..)
Muchas graciasx todo :)

Adjunto el report de Ewido y Kaspersky
