Windows OS transmitting data on network

2 machine, Windows 7 and 8 Pro, are using up bandwidth whenever the network adapter(s) are enabled.  The machines have been scanned numerous times for viruses and nothing comes up.

The machines are connected to the internet via satellite carrier and are using up the monthly bandwidth and I'd like to stop it from occuring.  Currently I turn the network adapters off when they are not in use but this is painful because it also stops me from using stored data on other machines.

I downloaded and ran TCPView, from Sysinternals, and have identified some of the programs that are using the bandwidth.  Problem is the programs using the bandwidth are programs I am not familiar with.

There are jpg's attached with a view of the output from TCPView.  Any help you can give me would be appreciated.

Just noticed that some are SVCHosts and I didn't get the programs running inside of them, I'll have to get that and upload it

What you showed does not seem too abnormal. My own machines transmit / receive that volume of data over some hours.

Open Resource Monitor (admin tools) and go to the network tab. You can let it run for a couple of hours and see what is using the bandwidth. It couple be updates (lots of those), Anti Virus Updates (uses bandwidth).

Of course, scan for viruses and malware also.

Disconnect the PC's from the internet when you don't want them to use it. There a many services, like Windows update, AntiVirus, other software that look for updates, Mail Clients, which constantly communicate with the Internet. Particularly many windows 8.x crapps will always want to communicate with the internet. Disable/uninstall the crapps, you don't need any of them, except maybe PC settings and the store...
Let's talk numbers.
What monthly bandwidth is consumed? How many days were needed to consume that, in other words, can you find out, what volume was used per day at least?
Without that info, who could tell if there's something abnormal going on? Modern OS' assume the pc is connetced and has a flatrate - that's how it is.

See the attachment for data useage.  Nothing remarkable was going on in that time period, no downloads.

Data useage is limited to 4gig per month

If nothing unusual is going on and since Windows, Anti Virus, email syncing and all that stuff normally takes bandwidth, then:  Do you have a problem?  And if so what it is do you think?
Wow. 2 GB a day and it "wasn't you"? That's really a lot.
You should use firewall rules to let only browsers do traffic and also the service "windows update".

Actually I turned windows update off because of the rash of updates lately, still a lot of date.

I won't have access to the machine for a couple of day, when I do I am going to try the resource monitor.  I had forgotten all about that

Let us know about Resource Monitor when you run it. Also update the machine when you get back to it. Microsoft is issuing lots of updates and it is best not to get too far behind.

One of the IPs in the image above is a Godaddy server.  Are you using email thru them?
c7c4c7Author Commented:
No, email is not through godaddy

I did not get access to the machines this week.  Hopefully by Wednesday

Using Resource monitor, TCPView and Task Manager I finally found some answers to what is causing some of the usage.
The largest offender was Malwarebytes looking for updates every hour, turned that back so it wasn't looking/downloading every hour and  things calmed down a bit.  

Then I found a uoipservice.exe that was causing a lot of net work traffic.  After that I also turned off One Drive to stop the syncing and changed the user account to a local account

There seems to be a fair amount of traffic between Microsoft and McAFee on the machine as well, I can't turn all that off so will have to live with it.  It's amazing the number of connections that are open on a machine to Microsoft at any one time

Thanks for the help
