Guys, do this, download Process Explorer, add the 'Network Recieves' and 'Network Sends' columns. Then Click on the network recieves column to sort it that way.
Check if you have the same symptoms as me.
In my PC, 2 svchost.exe processes are continuously receiving (and uploading!) data, albeit at a very low speed. But still significant. Over a 2 hours or so they've recieved 30mb of data.
Now I don't have any processes set to update/download or anything, so this is very suspicious.
I remember having the exact same problem last time, with the exact same conclusion, svchost.exe was continuously downloading stuff to my PC. So I got a bit investigative, downloaded NBMonitor and found out the IP from where this data was coming. A whois search on the IP showed that it was Airtel who was sending and recieving data to/from my computer. I don't know what 30mb of data is coming from Airtel's server into my PC, and what data are they taking, but I'm certainly not comfortable with this.
I ignored it then because it stopped recieving and sending when it reached around 40mb.
This is the older thread I made:
