I recently got cable internet. The first thing I did was to install Zone Alarm for a firewall.
Yesterday, I happened to run netstat, and was appalled to see some connections I just don't recognize. I ran a trojan scanner, as well as an uptodate McAfee, and they showed nothing. Nor have I detected any Trojan-like activity.
The unknown connections don't appear when I'm on dialup... only cable. I'd like to try blocking the ports just to see if I can keep them out totally. Is there a simple, Freeware utility I can use to do this?
