LOGANDK.DLL - just ran into this thing

I got home from work this morning and fired up my PC to play an online
game. BAM! it crashed after opening very sluggishly. Long story
short - something had infected my PC while my wife and/or daughter
were surfing last night. Adaware found some registry entries, so I
zapped those (machine was freshly scanned and cleaned before I left).
AVG anti-virus didn't find a thing. Still my games kept crashing
(DXDiag would hang too).

I found an "extra" task running that I wasn't used to seeing -
WINMGMT, and then I tracked that to a startup entry calling
C:\Windows\System\LOGANDK.DLL. The file was time stamped for the
previous evening. Aha! I had to boot into DOS (I'm running Win98) to
delete it, and then comb through the registry to find the startup call
and eliminate that. Finally, everything's back to normal. Whatever
it was, it does not appear to have caused any permanent corruption.

I haven't seen any previous references to this file, so I thought I'd
throw out this warning.
