computer attaccato da keylogger?

Messaggioda pepstatina » dom dic 11, 2005 2:43 pm

salve a tutti, ieri ho fatto uno scan con keylog detector, e secondo lui ho dei movimenti sospetti nel pc. Secondo voi, guardando il resoconto potrebbe essere così? Ho fatto anche uno scan con HijackThis del quale posto il risultato di seguito a quello di keylog.
Vi ringrazio anticipatamente per l'aiuto che fornite, ciao a tutti.

Per me non si vede un bel niente di pericoloso.
Non conosco quali siano i principi di scansione di quel keylogger, ma ha identificato file di programma/windows in uso e quindi soggetti a modifica in quel momento.
Infatti traducendo più o meno quello che scrive all'inizio in inglese ti dice: questi file sono sospetti ma vatti tu a vedere se sono pericolosi.

Il log di Hijackthis è pulito.

Grazie mille per la risposta, anche io pensavo che non fosse nulla di pericoloso ma ho preferito sottoporlo ad occhi più esperti.Grazie ancora e buone feste anticipate [:-D]
