Windows NT/2000/XP/2003
In Windows NT/2000/XP/2003 you will also need to edit the following registry entry for each user who ran the virus. The removal of this entry is optional in Windows 95/98/Me. Please read the warning about editing the registry.
At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.
Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export Range' panel, click 'All', then save your registry as Backup.
Each user has a registry area named HKEY_USERS\[code number indicating user]\. For each user locate the entry:

Close the registry editor.
More Information
Troj/BagleDl-H is a Windows Trojan downloader that has backdoor functionality.
When run the Trojan attempts to create the following registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
(Default)
ssgrate.exe
HKCU\Software\DateTime8
The Trojan listens on TCP port 31121 and waits for instructions from a remote attacker.
Troj/BagleDl-H then attempts to download a file from the internet to the Windows folder and run it.
The Trojan may also create a file ban_list.txt in the Windows System folder which is non-malicious and can be safely deleted.
Troj/BagleDl-H also tries to terminate and disable various anti-virus and security-related programs.
Sophos's anti-virus products include proactive protection technology, which can defend against new threats without requiring an update. Sophos customers have been protected against Troj/BagleDl-H (detected as W32/Bagle-Gen) since version 3.86.
