ho fatto una scansione antivirus dal sito security. symantec e mi ha trovato questi 3 virus. C:\WINDOWS\Downloaded Program Files\CONFLICT.1\gsa_1372.exe è infettato con Dialer.SPlanet C:\WINDOWS\Downloaded Program Files\celebrita1.exe è infettato con Dialer.MicroDialer C:\WINDOWS\Downloaded Program Files\gsa_1372.exe è infettato con Dialer.SPlanet poi il mio antivirus lo spybot e ad aware non mi trovano questi virus,come li elimino???La scansione on line li trova ma non li elimina

non mi è stato possibile eliminare le voci con la funzione cerca perchè non le trova,le scansioni in modalità provvisoria le ho fatte ma non ha trovato niente...c'è un altro modo per eliminare quei virus???

ciao Alfonso come faccio a trovare manualmente ciò ke mi hai detto????
devo avviare l'antivirus e poi cancellarli da la? e se si come li cancello???
cmq nn ho il cd di XP dovrei averlo???
mi sembra d aver letto da qualche parte che per formattare i pc con Windows98 si può fare anche senza il disco del programma è vero???
è lo stesso per XP???
grazie
