I recently installed a firewall and I am having great floods of scanners probing for netbus and subseven trojans. I have scanned my system with Mcafee, Nortons (enterprise), and Trend and show no trojans (or virus) on my machine. However I have caught windows explorer sending out on an undifined port. Does anyone know how to track this thing down? I have replaced the explorer.exe file but the scans still keep hitting me! <IMG SRC="smilies/eek.gif" border="0">
