This virus doesn't contain any destructive routine - it only tries to write the following message:
Virus napsany specialne pro inzenyra ZAKA ze SPS ******************* Nepodlehejte panice, mate nakazeno jen par souboru... (c) 1993 II.A 1988 Tak a ted si vyzkousime treba: RESET Kdyby kazdy nespokojeny student napsal virus, tak v nasich skolach by ani jiny software nekolov al a McAfee by se divil...
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:
Nesedte porad u pocitace a zkuste jednou delat neco rozumneho! ******************* !! Poslouchejte HELLOWEEN - nejlepsi metalovou skupinu !!
This variant also has a different xor-coding constant, it activates on November 1st when it reboots the machine.
