This is a stealth boot sector virus. Unlike most other boot sector viruses, RP does not decrease the total amount of DOS memory; instead it decreases the amount of free memory.
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.
You may also refer to the Knowledge Base on the F-Secure Community site for more information.
RP activates on the 17th of December. When the machine is booted on that date, the virus decrypts a message, switches the display to 40 column mode and displays the following text:
RP wants to say hello!
After this, the virus overwrites part of the hard drive, making the machine unbootable.
The virus is buggy and often crashes when infecting a floppy. RP was reported to be in the wild in Hungary and Denmark in January 1996.
