How can I discover what app/process is stealing my bandwith (W10 Home)
Hi
I am in a remote part of the world with limited access to networking. I am using a 3G mobile/cell USB modem with cellphone sim card to get internet access. I only get 2.5GB allowance per month.
Every day when I first connect to the network, *something* on my computer downloads 130MB of data. Every day! This mystery app/process is using up my whole data allowance! How can I find out what it is and stop it, please?
I suspect it is these:
PID Address
scvhost.exe (netsvcs) 476 14.40.233.105
scvhost.exe (netsvcs) 476 14.40.233.112
scvhost.exe (netsvcs) 476 14.40.233.50
scvhost.exe (netsvcs) 476 14.40.233.106
scvhost.exe (netsvcs) 476 13.107.4.50
...as they all go crazy (network Bytes/second) in the Network view of Windows Resource Monitor while the download is happening.
Process Explorer by Sysinternals shows one scvhost.exe (C/Windows/System32/svchost.exe (netsvcs)) file getting very busy (CPU usage) at the time of the download. That particular svchost.exe has these processes associated with it:
Application Information [AppInfo]
Computer Browser [Browser]
Delivery Optimisation [DoSvc]
Geolocation Service[ifsvc]
IP Helper [iphlpsvc]
Remote Access Connnection Manager [RasMan]
Server [Lanman Server]
System Event Notification Service [SENS]
Shell Hardware Detection [ShellHWDetection]
Themes [Themes]
Task Scheduler [Schedule]
UserProfileService [ProfSvc]
User Manager [UserManager]
Windows Push Notifications System Service [WpnService]
Windows Management Instrumentation [Winmgmt]
When whatever-it-is has finished downloading its 130MB, it goes quiet and doesn't generate any more traffic until the next day.
The regular Windows 10 task mananger doesn't show any network traffic at all. I guess that it doesn't recognise my USB modem as a network interface.
I have turned off all the "auto-updates" I can think of (Avast, MBalwarebytes, Firefox extensions). Windows updates is set to "Do not Download over metered connections" I have even tried turning off Windows Updates entirely, (plus Skype Updates, Googleupdates) under "Services" in Control Panel.
How do I discover what it is that is doing the downloading and turn it off? thanks.
The machine shows-up as clean in Avast, MBalwarebytes scans.
OS: Windows 10 home, latest build.
