Hello there admins and fellow forum members:

Well, I have to say that Malware Defense/krl32mainweq.dll was one hell of a clever trojan. I spent all weekend battling with it, and I seem to have removed nearly every trace of it thanks to the wonderful tutorial on this website. However, there's one thing I can't seem to fix.

Simply put, my audio doesn't work. The speaker icon in the lower right corner of the screen displays an X next to it. When I try to open Volume Mixer, it says

"No audio device is installed".

However, when I go into the Device Manager, everything seems normal. The driver is Conexant High Definition Audio. When I look at driver details, the following are listed:

C:\Program Files\CONEXANT\CNXT_HDAUDIO\UIU32a.exe
C:\Windows\system32\CnxtAp32.dll
C:\Windows\system32\drivers\CHDRT32.sys
C:\Windows\system32\drivers\drmk.sys
C:\Windows\system32\drivers\portcls.sys
C:\Windows\system32\SysFxUI.dll
C:\Windows\system32\UCI32A29.dll
C:\Windows\system32\WMALFXGFXDSP.dll

I've already tried uninstalling/reinstalling the driver, but that didn't work. Anyone have any ideas? Perhaps some files are missing? Should I post a HijackThis or Malwarebytes log just for the sake of being thorough?

Any assistance is greatly appreciated.

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

I've been fighting this for days. There are 10000 answers out there and I've tried every one I've come across, and still "no audio device". I'm looking at a clean wipe if I can't do this within a few more hours.
