ip rules help (urgent)
this morning i realized my windows 2000 system has around 20 (yes 20) tcp connctions established to various web sites and irc servers
it's probably a trojan or a worm of some kind....
before i investigate i'd like to cut off all access on all ports besides http access (wanna still be able to browse)
how can i make that happened either from within the OS or open source solutions only

Have you got a firewall? If not, look into something like ZoneAlarm or Outpost. Both easy to install and free versions are available.

First, go to www.moosoft.com and download the trojan cleaner. Next, you can get tcpview from www.sysinternals.com and look at a realtime view of what is happening on your box. Follow up with process explorer to see what processes are participating. Once you hae a good idea, run the trojan cleaner and then install one of the many free personal firewalls and consider this a nice learning experience.
Best thing to do is not panic. Go through the above light remediation to determine exactly what is happening, then clean your box if it does turn out that you have a trojan, then protect it from future attacks with a personal firewall.
This is the best I can do for you with the info you provided. Hope it helps out.
