I'm about ready to gouge out my own eyes in frustration over malware (in c:\windows\system32\pmnlk.dll) that refuses to die. It causes irritating pop-ups in IE, but who knows what else--my google search suggests this file has been linked to a variety of problems. After trying the other suggestions on the Forum (I know where the bugger is on my system, but Autoruns and Spybot can't remove it as it's "in use"; Ad-Aware doesn't even detect it), I finally downloaded HijackThis in order to post a log and ask for help.

My HijackThis log file is below. Please note that I know, from my scans with other programs, that pmnlk.dll has infiltrated the following (which, interestingly, didn't show up in the HijackThis scan):

-it's running as a module in the process C:\windows\system32\lsass.exe (trying to kill this module in Spybot caused the system to crash, and it re-installed on startup)
-it's autorunning as BHO {FB2B7947-8CFD-4154-8FDC-26ABCD8D410A} (it respawns/reactivates immediately when I tried to delete/disable it in Autoruns and Spybot)

Actually, now that I've double-checked it, HijackThis doesn't detect *any* BHOs, even in the detailed startup scan! I know this is wrong, because Autoruns and Spybot both detect BHOs for my Google Toolbar, Adobe PDF, RealPlayer, JAVA, and Spybot itself. Hmmm....very weird.

Thanks in advance for any help you can provide,
Matt H

A bit of new info that might help (especially since I see a flood of people with the same problem): I ran HijackThis again using the ADSspy utility. It doesn't find anything on a basic Windows scan, but when I scanned everything, with no exclusions, I got this little gem:

c:\windows\system32\svchost.exe: exm.exe

which google tells me is ADS malware. What should I do with it? Am I going to corrupt Windows if I delete it with HijackThis, since svchost.exe is a legit program?
