High Traffic Transfer With No Active Connections

Fumega

Hi, I was browsing on the Internet today. When I closed Firefox and opened DU Meter, I saw that a high data transfer (download) was being made (1.4 MB/s).

I had no idea why was all that data being download to my PC and where it all came from, so I ran a netstat command, and the only opened connections where FIN_WAIT_2 and close_WAIT. I checked with my Bitdefender firewall and no applications were transferring data.

I'll attach some printscreens.

Where is all that traffic coming from?

Kind Regards.

By the way (I cannot edit the post I don't know why).

I have the BitDefender Total Security 2010 updated and the last total scan was like today at about 2AM.
