podrias mirar las conexiones salientes el inicio en windows en las carpetas %appdata% %temp% (varia ya que en muchos malwares tenes la posibilidad de modificar donde se guarde) activando ver archivos ocultos.

Buenas tardes,
Aparte de pasar un Antivius o Antimalware, ¿Hay alguna manera de detectar si en un equipo hay instalado un Keylogger?
Aparte de mirar el árbol de procesos. Algún comportamiento extraño, o algo así.
Saludos!

¿Que pasaría si el Keylogger es local y no remoto?... :-X
