I am dealing with a annoying virus. Yesterday my tenant gave me USB to scan. I scanned it with ESET and removed all the viruses. On next restart i noticed that my hidden folders were not displaying even i change settings in folder options. Then i formatted H: drive (in which Avira detected viruses). But still problem is not solved and Avira notifying me about virus present in H: drive and still hidden folders are not displaying. Please help anyone .
