I have kept the definitions up-to-date, and this seems to be an old virus.
Yesterday boot scanning found:
Trojan.Dumaru [Spyware Doctor]
Backdoor.Nibu [Symantec]
Troj/Dumaru [Sophos]
Backdoor.Dumador [Kaspersky]
Threat Level: High
Author: Smash and SARS
Advice: Toss
Spybot S&D: Full system scan found only 3 local_machine\software\microsoft\Security Center Firewall & Antivirus\ setting changes.
All product ignores are off.
How can I get S&D to find & toss this well known old trojan?
