Does anyone recommend a util for scanning my own ports to check for security holes/trojans. I'm using Tiny Personal Firewall 2.0.15 and it has picked up a lot of activity from the Dal.net servers. I dont use irc so can only assume I may have a Trojan somewhere. Theres also a lot of incoming TCP connection attempts from other servers. I run NAV 2002 and it hasnt picked anything up. I dloaded Swat It and have also run that, it doesnt find any trojans. Cheers.
