Hi Kurt!
10 Dec 96, letter Kurt Wismer to Alexander Kovneristy:

    Not all integrity checkers requier clean boot from a floppy disk. For 
example ADinf scans disks by direct call to BIOS entry point and implements 
FAT and VFAT functions inside the program. So it can find every stealth virus 
without clean boot. More over! ADinf implements special alghorithms which 
compare information obtained by direct disk access sector-by-sector throw the 
BIOS and information obtained by DOS functions. This comparation implemented 
in ADinf can find any new active stealth virus. So stealth mechanism helps to 
find infectors! :-)
                                With best regards,
                                    Dmitry Mostovoy
