Hi, I'm encountering a powerful malware. So needs help to remove this malware. Hope u guys can help me out.

My Windows XP SP2 is infected by this malware, Trojan-Downloader.Dadobra.CP, as labeled by Spyware Doctor.

There're a few programs that will tend to hang easily, especially when they're running simultaneously. These programs're BitComet 0.96, Windows Live Messenger 8.1 & Mozilla Firefox. After hanged, the programs can't be killed.

Restart is not possible as well. Although the Windows will closes all other programs, but will not start restarting the pc.

Besides, my NVidia overclocking utility, D.O.T.(Dynamic Over-Clocking Technology) seems to be infected, or maybe is rundll32.exe that gets infected, bcoz whenever I enable or disable my D.O.T. feature, my Spyware Doctor will block rundll32.exe's attempt to write the registry: HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURR ENTVERSION\RUN, WinSys="C:\WINDOWS\System32\WinSys.exe". Maybe is rundll32.exe gets infected instead of the D.O.T..

Another symptom is that my Windows will appears to locked after my programs hang. The 'Unlock Computer' window will appears when I try to log off or switch user. However, unlock the computer using other user accounts in my pc can't works, but unlocking using the logged on user account works.

I've tried wiped my system partition & reinstalled my Windows, but my fresh Windows experiencing this same prob within 12 hours! So, I'm suspecting that the malware is exists in my other partitions. Wipe my other partitions as well? But I've a lot of data in my other partition, so backing up the data might backing up the malware as well? Or is my speculation wrong?

Above symptoms're juz for reference for any possible solution. So, if anyone knows solution to this prob, plz let me know. Anyway, I'm expecting extensive removal instruction to this Trojan-Downloader.Dadobra.CP. Any help is greatly appreciated. Hope to hear from u guys soon. Thx in advance! ^^
