Salve,
vi riporto il file di Log, salvato dopo aver fatto partire HiJack This.
Mi sono ritrovato nell'esecuzione automatica, due voci sospette, explora e task, e dalle informazioni prese su Internet, dovrebbe trattarsi di un trojan, giusto?
Cosa mi consigliate di fare?

Grazie e buon lavoro.
Cari saluti.

Fai una scansione on-line :

E dimmi se ha trovato qualcosa. Se non ha trovato niente,per scrupolo, fanne un'altra con Kaspersky.
