I know this is a very old post, but I have had this identical issue for two days and I did find the culprit. In the Windows/system32 folder I found a file called "winthemes_service.dll" which was proliferating rundll32.exe files. As time went on I would have a hundred or more on my win xp system. I opened windows in the safe mode and simply did a search for this file name and deleted it. Case closed... Hope this may help someone else...

1- Open your Task Manager and stop viral rundll32.exe process. You can detect it by the high usage of CPU (ranging from 40% to 100%);
2- Open Registry Editor, by pressing Win+R buttons and typing regedit in the line. Then navigate the following Registry Keys and remove them:
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN\XTray.exe
3- Find all the files that can be called like rundll32, except the file that exist in C:\Windows\System32\ folder
4- After that you should do the full scan of your computer with the help of a powerful antivirus program.
That worked! Thank you very much man really appreciated
