I am using limited BroadBand ( I can use up to 3GB per month). BroadBand company charges extra money if I use beyond 3 GB.

Everyday one ( or more) background process utilizing 75 MB of Internet Data. I have been monitoring Internet data usage through NET METER tool.

Initially I suspected AVG anti virus S/W so I uninstalled it, but it doesn't solve the problem.

Note: I have closed all Net browsers to confirm background process network utilization.

Can you please tell me , how can I identify background process which is utilizing 75 MB on everyday ?

If you have Windows 7, you can look in the Resource Monitor to see what applications are using bandwidth. Open the task manager (Ctrl+Shift+Esc), go to the Performance tab, and click on "Resource Monitor". On the "Network" tab, click on the column heading "Total (B/sec)" to sort the processes by total usage. This will also show you what server the process is connecting to, which can be useful for determining what a process may be doing.

You could try a software designed to that:

This one shows network usage by process.

Windows Update tends to use some bandwidth. Other software that could also consume bandwidth could be viruses. Use Wireshark to monitor the network traffic on your Network Interfaces

Also, you could use a little tool called process monitor to monitor the most active disc IO on your PC. The latter one I'd recommend using while your PC is completely idle!

you can use NetLimiter.

the free version will show a list of your processes and their bandwidth usage. =)
