Technical Details


It’s a memory resident dangerous virus which hooks INT 9, 13h and
infects the floppy Boot-sectors by a virus “Brain” algorithm. It
moves the TSR part into the memory at a random address and does not change
the system areas. It can cause the computer to hang-up. This virus checks the
keyboard and beeps when the Alt-Ctrl-Enter pressed. It also erases the FAT
and DIR sectors of the drives.
