Salve a tutti. Ho un problema con un trojan che si è dimostrato una brutta bestia. AVG riconosce come trojan il file uyxff.exe (Generic Downloader) ma non riesce a farci niente. Hijack non riesce a rimuovermi le due voci F2. Perfino modificando le due chiavi del registro relative a uyxff.exe e gtfjpnn.exe, dopo mi ricompaiono uguali!! Con Google non ho trovato NIENTE su questi due file. Come potete immaginare sono piuttosto diperato... Ogni aiuto sarà ricompensato con gratitudine eterna!
