hi, i am jai and i have been experiencing a strange problem.I got a new antivirus , NOD and it cleaned lot of viruses last week, two days later i found that i cannot see my hidden files even if i am going to tools>folderoptions> show hidden files. i click this radio button and i go back and see it is not clicked. no hidden files become visible. i am the administrator, so i think the issue is not about rights. could some one suggest?
