It might not be a virus/trojan inside your PC, it might be someone trying to get one in and overflowing your TCP/IP stack.

Block the following ports in your personal firewall or router/hub and the problem might go away
(even if it doesn't solve this problem its a good idea anyway for future protection).

port / traffic type / in or out / why

135 UDP NetBios - Both Net Send Spam/Pop-ups, Worms;  
135 TCP NetBios - Incoming Net Send Spam/Pop-ups, Worms;
136-139 UDP, TCP NetBios - Both Worms, Network Neighhood;
445 TCP MS-DS/NetBios - Both Worms, Network Neighhood;
1433 TCP MS-SQL - Inbound Worms, Trojans;
1434 UDP MS-SQL - Inbound Worms, SQLslammer;
1900 UDP MS-DS/NetBios - Both Worms, Network.
3127 UDP,TCP
