This is a boot sector virus, which infects the DOS boot sector on
hard drives (instead of the usual MBR). It stays resident in low
system memory in the interrupt table. Virus contains several bugs
and may often crash the machine. The virus also reinfects floppies
every time they are accessed.
Bug has no activation routines, it just spreads. Virus uses hex value
070A as an infection marker and as a backdoor to original INT 13h, hence
the reference to 70 in some alias names for this virus.
Bug has been reported to be in the wild in Norway and Finland during
1996.
