Hey,
A couple things...first are you sure something is being downloaded or is a process just running or both?
I would disconnect yourself from the internet or wifi or hardwire or whatever during the times which you think it is downloading and then take a look at your system processes that Boli mentioned earlier to see if anything is running. If something is running, you likely have a virus or trojan or something of the sort.
If not, someone may be using your computer to send information or whatever...as others have mentioned, try a packet sniffer such as wireshark but unless you know what you are looking at it may not help.
A little computer geeky is Snort, there are rules based in the program to help identify suspicious traffic.

You can also download Nmap, which is a port scanning tool to see if your firewall is weak and/or someone is finding something open on your computer. google "what is my ip address" and then type that into Target area and hit scan. Some ports may be open, just google them to see if they are used for everyday use such as http which is port 80. If you have a bunch of ports open, you may want to look into a better firewall.

Alternatively, you can use Shields up which will also scan your computer for open ports, however, you must be directly connected to the internet...meaning not running through a router. In a perfect world, all your ports will come up as "stealth" meaning no one knows they even exist on the internet.

Hope that helps. Good luck. In any case, I would back everything up on that computer that you deem important to an external hard drive or something. If your computer is infected it may be best just to wipe the OS and start over.
