Allora...

ho eseguito alla lettera ciò che mi avete consigliato e adesso sembrerebbe tutto a posto, se non fosse che facendo la scansione online con il Norton mi rileva 8 file infetti che invece non trova facendo la scansione direttamente con il Norton installato sul pc(peraltro aggiornato).
Questi sono i risultati della scansione online:



" 79975 file esaminati, 8 file infettato/i.

Nella memoria non è stato rilevato alcun virus.

La scansione ha rilevato uno o più virus nei file esaminati.
