Affected registry keys are: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\ HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run Registry keys added include: Netbus Server Pro PATCH "C:\windows\patch.exe /nomsg" - note: the entry may not necessarily be called PATCH NetBuster = "" SysCopy = "command /c copy %windir%\\keyhook.dl_ %windir%\\*.dll /Y" Rundll32 = "rundll.dl_ /noadd" Rundll = "regedit /s nbsetup2.reg" Later versions may also add one of these registry entries: HKEY_LOCAL_MACHINE/SOFTWARE/UltraAccess Networks/NetBus Server/ HKEY_CURRENT_USER/NetBus Server/ These entries should be deleted. The files rundll.dl_ (note the underscore, this is important) and nbsetup2.reg should be deleted if they exist. Ending the process is necessary. A reboot of the infected machine is recommended.
