I have a XP Pro system that got infected with  the Vundo Trojan.  I feel confident that I have remove it from the system.  There is one issue still lingering.  Upon start up a "RUNDLL" error occurs with thefollowing:

 c:\windows\system32\yohefani.dllm could not be found.

I have done the Google thing, with a bunch of hits for products that will remove the problem.  Before I spend any money I thoguht I would ask to see if there was another way to resolve this issue.

I would install Microsoft Security Essentials
Then download AutoRuns

This should show you that dll, you can fix it manually.
Go into MSConfig and see if the dll is listed from there. If so, then uncheck it.
Next, go to regedit and go to HKEY_LM\Software\Microsoft\Windows\CurrentVersion\Run. Look for entry there.
Delete it if found.
