My Anti Virus software (AVG Free edition) recently found a Trojan horse called Downloader.Generic.OAX.
I used AVG to delete the threat and it has not been detected since.
However, every time I run spybot it finds a registry change;

Windows.ActiveDesktop: User settings (Registry change, nothing done)
HKEY_USERS\S-1-5-21-1195745321-4289944141-1504440272-1007\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesktop\NoHTMLWallPaper!=W=1


I am not sure if its connected to the Trojan horse, but I have not been able to fix the problem using spybot.
Spyware doctor and adaware also detect a registry change but cannot fix the problem

I have used HijackThis to run a scan of my registry and have attached the log file it produced.
Please can someone advise me further.

Hello thefaz and welcome to the BC HijackThis forum. I don't think that any malware would be making that setting in the registry. It is a setting used to protect a system from having anything but bmp files set as the desktop background, thus preventing malicious html pages or jpeg files to be loaded as a background.

It is more probable that the entry keeps coming back due to WinPatrol or Spyware Doctor protecting the registry from any changes. If you want to remove that entry from the registry then you will need to first close any registry protecting programs which prevent changes. Once the entry is removed then reboot the machine and let the protection programs start up again.

Other than that the HijackThis log is clean. You are good to go.

Cheers.
