More Information
Troj/Sdbot-HE is a backdoor Trojan which runs in the background as a service process and allows unauthorised remote access to the computer via IRC channels.
The Trojan copies itself to the Windows system folder as MSVDM6.EXE and creates entries in the registry at the following locations to run itself on system restart:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Registration Service
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Registration Service
The Trojan remains resident, listening for commands from remote users. If it receives the appropriate command the Trojan attempts to copy itself to remote network shares with weak passwords.
