Folder Options is removed from Tools in Windows by a virus. The virus is called W32.Rontokbro@mm OR W32/Rontokbro.gen@MM
The removal of this virus is slightly difficult. Antivirus can't remove
it automatically. However detailed procedure to remove it is available
About this Virus/Worm:
What it does is creating new files which looked like a folder but its
actually a .exe file. Unless you’ve enabled the view extensions in the
folder options or else you won’t see the .exe extension of the file.
The file is approximately 43.7Kb and normally people will click to open
it because it looked like a folder. So after you’ve open it, the virus
will run each time during startup and keep on spreading and spreading…
into the harddrives.
More troubles coming up. Normally when you click “Tools” in explorer,
there’s a “folder options” underneath it. Once the pc is infected with
the virus, the Folder Options will be missing, which disabled you to
change the options to view the extension of the files. So when you see
a new folder appeared from nowhere and you clicked to open it out of
curiousity, the virus spread more again. Moreover, the virus disabled
the registry edit where you will see this message “Registry edit is
disabled by the administrator” everytime you try to edit the registry.
So how to clean the virus then? I found some solution from the following link and have successfully cleaned it from my system.
It will help you to get rid of this virus named W32.Rontokbro@mm aka brontok.a and to get back your hidden files.
