There are some common viruses, their first work is to attack “Folder Option”. They disable Hidden Files & Folder; then they create some annoying script as Hidden. The fact is: user can not delete or control these Hidden files.

User have to do some Registry Edit thing to show Hidden Files & Folder.

1. Go to Start>Run
2. Now regedit
3. Press Enter.
4. Registry Editor will open.
5. Now search User Key from below & Change the value.

User Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\
Advanced]
Value Name: Hidden
Data Type: REG_DWORD (DWORD Value)
Value Data: (1 = show hidden, 2 = do not show)

User Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\
Advanced]
Value Name: ShowSuperHidden
Data Type: REG_DWORD (DWORD Value)
Value Data: ( 0 = Hide Files, 1 = Show Files)
