Salve, è da un po' che non entravo nel forum...

Oggi ho deciso di fare una scansione completa al mio pc, non che notassi nulla di strano, però ogni tanto la faccio.

Il mio pc è un acer e ha un sistema operativo windows 8.1, come antivirus uso Bitdefender Total Security.

Il risultato della scansione non rilevava nulla di infetto, però dal log ho notato che alcuni files sono stati ignorati sia perchè non trovati sia perchè protetti da password.
Ora mi chiedo se tutto ciò sia normale.

Vi posto il log coi file di cui parlo.

E' tutto nella norma?

Grazie.

La scansione l'hai fatta con Bitdefender ?
Gli elementi non trovati sono tutti file di sistema tranne gli oem, non conosco bitdefender devi guardare nelle impostazioni dell'antivirus.
Quindi non posso dirti se è tutto a posto, se vuoi posta un log di HijackThis e ti saprò dire.

Buongiorno,

ecco il log con scansione:

Penso sia stato installato a mia insaputa, ho bitdefender versione a pagamento sarebbe stato inutile avere anche avast, anzi può entrare in conflitto..provo a rimuovere da hijackthis
Il pc ora è più veloce, non che avessi problemi o errori prima, ma comunque più veloce.
Grazie dell'aiuto :)
