Hi Mushy J
That is definitely left over from some malware that has been removed from your PC, the dll is not recognized library, there must be some reference to that in your Startup processes - you need to remove that
Task Manager and indeed Msconfig offer only limited control over Startup items . . .
Click the link below to download a small free utility that does not require installation
When the file downloads, unzip it.
Depending on your system, run Autoruns or Autoruns64 as Administrator
With that utility, on the initial list and on the Logon Tab, look for any reference to winscomrssrv.dll, then right click and delete that reference . ..
