Is there a startup entry for wmon16.exe, either in the
Registry or StartUp folders?

Also, have you sent a copy of the file to your
anti-virus vendor?

What does? wmon16.exe? Are you sure?

What does? wmon16.exe? Have you used fport.exe or
openports.exe to confirm this? Also, are these the
source or destination ports?

A little digital detective work will help you tie the
symptoms to the file you found, if that is in fact the
case. Kill the process, remove any Startup entries,
and restart a machine. If the process returns, then
you need to dig deeper.

HTH,
