Netman (Network Connections Service)

When I first boot up my computer, SVCHOST runs at 50% cpu time. If I "Go
To Service" I notice the same services associated with this particular
errant SVCHOST processes. Stopping them one at a time yields no change in
processor usage until I try and stop NetMan "Network Connections" service.
Processor time drops almost immediately to normal. Restarting the service
does affect the computer

 

Hi
Use this utility and check whether the computer is running unexplained
Network activity.
