Technical Details

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.
