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).
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.
