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.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
More information on scanning and removal options available in your F-Secure product can be found in the Help Center.
