There are two variants of 'DelPart' trojan. They are both small
COM programs. Being run the first variant of the trojan erases
(fills with zeros) Master Boot Record on first and second hard
disks and exits to system.
The second variant erases (fills with zeros) MBR and DOS Boot
Record on first hard disk and outputs a message: 'Partition table
and boot record successfully deleted!'. If any of operations fail
the trojan outputs: 'Partition table or boot record don't
deleted!' and exits to system.
