This is a harmless memory resident multipartite encrypted (in files) virus. It infects both COM and EXE files. On execution of infected file it hits MBR of hard drive. On loading from infected disk it hooks INT 08h, waits for DOS loading and then hooks INT 21h. It writes itself at the end of files that are executed.
This is a stealth virus on accessing to infected hard drive, it hooks INT 13h to use that function.
Sometimes this virus decrypts and displays:
Nech zije Jozef Tiso, prvy slovensky prezident !
