Posso eliminare file infetti del registro?

[crosbi]

Salve, avevo fatto circa un mese fa la stessa identica domanda. Purtroppo è ricapitato e non so mai se si possono eliminare. Il fatto è che una volta che li ho eliminati è andato in blocco il sistema e quindi sono rimasto abbastanza terrorizzato.

Grazie mille!
