More Information

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Configuration
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Configuration
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\Configuration

W32/Sdbot-ML connects to a remote IRC server and allows a malicious user remote access to an infected computer.
