How can I stop this remote attack?

Someone appears to be logging into my machine remotely, I am running Avast anti virus with Comodo Firewall both report no attacks.I only noticed this because on my router security logs I see the following.

I have scanned the machine with 6 different anti virus scanners and all report the machine is clean, so it's probably a zero day attack. It happened after I stupidly downloaded a .doc from a torrent. I suspect a Trojan on my machine, is there anyway I can block this attack and find out manually which program is dialing home to the attacker?
