After this the virus waits for a keypress and then resets the machine.

The 1376 bytes long variant is nearly identical to the Helloween.1839 described above, but it displays this message:

!! Poslouchejte HELLOWEEN - nejlepsi metalovou skupinu !!

This variant also has a different xor-coding constant, it activates on November 1st when it reboots the machine.
