I get a pop-up notice:"16 bit MS-DOS Subsysten: C\..System32\SYMEVENT.SYS

I ran Autofix for my installation of N360 and found no errors.  I used to have Norton SystemWorks Premiere installed.  I removed it when I started getting this error:

  "16 bit MS-DOS Subsysten:

    C:\Program Files\Cisco Aironet\cscodiag.exe

    C\..System32\SYMEVENT.SYS, An installable Virtual Device Driver failed Dll initialization.  Choose close to terminate the application.  [Close] [Ignore]. 

 

I checked \system32 and SYMEVENT,SYS is gone.  I can't find where it's hiding. My wireless adapter is working fine (since I'm here)

 

TIA
