Hai eseguito le operazioni in Modalità Provvisoria?

Se non si cancellano allora sono legate a qualche virus, in questo caso devi formattare il disco e reinstallae tutto.

In questo LOG non vengono caricate, forse non riesci a trovarle.

Adesso sono ricomparsele righe

ma non ci sono file sospetti da eliminare, potrebbe trattarsi proprio dell'azione di un virus, il Norton non indica nulla?
