This is a typical boot sector virus, spreading via floppies.
The virus contains an encrypted message and code to display it, but this routine always fails. The encrypted text reads:
the UNashamed Naked!
Otherwise the virus does nothing but spreads. This virus has been reported to be in the wild in several locations, and is especially common in Africa. The virus can be disinfected from the hard drive with generic means (ie. FDISK /MBR after a clean boot if the hard drive is accessible normally).
Allow F-Secure Anti-Virus to disinfect the relevant files.
For more general information on disinfection, please see Removal Instructions.
