da cui è evidente che nelle due righe F2 è presente il malware.
Ora se io fixo (ma no mi è chiaro il concetto di fixare) queste due stringhe non corro il rischio al riavvio di non riuscire a far partire nulla dal momento che è compreso anche il file system.ini e che quindi elimininandolo si trascinerebbe explorer.exe, windows. Forse faccio confusione lo so, ed è proprio per questo che non avendo chiarissimi i concetti di windows chiedo aiuto qui.
Io pensavo di fare così: avviare il regedit e nelle stringhe interessate eliminare solo la voce __p9hEPQkbj e solo quella lasciando inalterata il resto della stringa. Potrebbe andar bene?
Ringrazio anticipatamente.
