suspect .dll file and no sound

I recently got rid of the siszyd32 trojan with MalwareBytes but there is still an entry in the startup tab in msconfig that wasn't there not long ago, esafoqesidanape is the name of it. I found a .dll file by that name in my windows folder, also a registry entry, and I can't delete either. I've run Avast antivirus, AdAware, MalwareBytes, Hijack This, and SpyBot. The registry enty is:

04-HKLM\..\Run: [Fwirayazadahigu] rundll32.exe "C:\WINDOWS\esafoqesidanape.dll",Startup

Startup is extremely slow, takes 15-20 minutes or more and my sound is gone. Otherwise, my computer runs fine. In device manager, 7 entries under Sound are disabled--6 are Microsoft Kernel, the 7th is Multimedia Audio Controller. For the Microsoft Kernels, I found this message: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)". For the Multimedia Audio Controller, it said that the drivers are not installed. I tried to reinstall them and it wouldn't do it. Could this be related to the malware problem? I got a new sound card a year or two ago.

I appreciate any advice you can give me.

Most Virus and Spyware scans are likely to work better in Windows Safe-Mode.

I could uncheck esafoqesidanape in msconfig.
I did that back when the MSBLASTER worm started.

You could remove any bad msconfig entries in Registry at

OK, I went into safe mode & deleted the .dll file & also the registry key & rebooted. When I rebooted, the file was still deleted and it was gone from the startup tab in msconfig. The registry key was there again but I deleted it and for now it's still deleted. On reboot, I got a message saying it couldn't find the .dll file, so something is still calling for it.

Still don't have any sound. I guess I'll see if I can another way to install new drivers.
