Ciao, il log è a posto, non hai detto che problemi hai.

Dovrebbe riguardare Nero ma non è sicuro. Nero 10 è un programma commerciale, lo hai acquistato o hai scaricato la vs in prova, se è la vs prova ti consiglio di rimuoverlo e fare una pulizia con Ccleaner, se vuoi un ottimo sw per masterizzare gratuito ti consiglio QUESTO scarica la vs win EXE.
Facciamo un controllo, installa Malwarebytes QUI lo aggiorni e poi fai una scansione COMPLETA non rapida, elimina quello che trova.
Fai sapere. Ciao

Succede spesso ti dicono download gratis ma si tratta di programmi in prova, nessun pericolo ma è sempre bene controllare, quando ti servono sw, controlla prima su aiutamici ne trovi moltissimi tutti gratuiti e testati.
Ciao
