I had success on several computers catching IRC Bots with SwatIT, which is free.

Subject: Syn Flood

 

 

I have a problem on a home PC of all things. Every once in a while it bursts into life and syn floods an IP address on port 80. The IP addresses it chooses are random and varied. The network counters ratchet up alarmingly (as viewed in the connections window). I am running winXP Pro on this box.

 

I have zone alarm, an SMC Barricade firewall, and Norton anti virus.

 

I don’t seem to be able to catch the computer at it, I just have the evidence after the event. I don’t like the anti social behavior that this is exhibiting and am wondering if the collective wisdom of this group might have any ideas how to track the issue down.

 

According to virus checkers, I am clean.

 

Thanks in advance
