More Information
W32/Rbot-GHT is a worm with IRC backdoor functionality for the Windows platform.
W32/Rbot-GHT runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
When first run W32/Rbot-GHT copies itself to <Windows>\directxclickers.exe and creates the file <Current Folder>\directxclks.sys.
The file directxclks.sys is detected as Troj/NtRootK-F.
The following registry entries are created to run directxclickers.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Microsoft Directx clicks
directxclickers.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Directx clicks
directxclickers.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Microsoft Directx clicks
directxclickers.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Directx clicks
directxclickers.exe
W32/Rbot-GHT sets the following registry entries, disabling the automatic startup of other software:
HKLM\SYSTEM\CurrentControlSet\Services\wuauserv
Start
4
HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess
Start

Note: disabling autostart for the SharedAccess service deactivates the Microsoft Internet Connection Firewall (ICF).

Microsoft Directx clicks
directxclickers.exe
HKLM\SOFTWARE\Microsoft\Ole
