Remove brontok virus manually

"Brontok virus" came from Indonesia.After infecting with this virus in the first run, it copies itself to the user's application data directory. It then sets itself to start up with windows, by creating a registry entry in the HKLM\Software\Microsoft\Windows\CurrentVersion\Run Registry key. It disables the Windows Registry Editor (regedit.exe)and modifies Windows explorer settings. It removes the option of "Folder Options" in the Tools menu so that the hidden files, where it is concealed, are not easily accessible to the user.
