Why is my laptop hogging so much bandwidth?

I am on a 30Mb connection which is shared with two other people in the household. I have a laptop dual-booted with Windows 7 and Ubuntu. When the laptop is switched off or booted into Ubuntu we get average to good connection speeds all around. Once I'm logged on to Windows 7 however, the connection on any other device connected to the same network drops considerably. I could get an excellent connection on my Nexus 7 but as soon as the laptop is fired up it's like I've been thrown back to 1998.

My brother is insisting it's a virus but I see no evidence of this. All of my scans in MSE have come back clean. It's not that I'm downloading torrents or playing online games either, I could just be browsing these very forums and the problem persists.

How could I go about pinpointing the root of the problem? What measures are there to monitor outgoing traffic from my laptop?

Try Malwarebytes (free version).

Can the router show you what the network traffic actually is, rather than relying on a subjective feeling of 'running slow'?
