Hey Hey

My firewall log shows a lot of attempts by different people to Tracert my pc.The source and the destination ports are both 6346.This means that there's some trojan in my pc and the dumb lamer is using some canned client program.My dumb anti trojan software doesn't detect it.. Is there some way i can just stop all activities in a particular port (6346!) ?? or is there some really good and free antitrojan software ????
I use a firewall called Omniguard... the problem with it is that when i use it i can't use any instant messengers or p2p ... Reminds me of what Peter Norton said about internet security
" Security is inversely proportional to convenience "
So are you running the software or not? I'm guessing yes if you have a firewall log. I'd suggest you check out other firewall software. Tracert.. Trace Route is a method of determining the number of hops between two points and the path the packet takes. This is done using ICMP, so you shouldn't be seeing any ports on these attempts... You also said these are attempts, this doesn't mean any connection occurred... It's not even proof that that port is open on your PC... just that someone checked to see if it was. The odds are you don't have a trojan... and most AV software these days will pick up trojans, so grab a copy of AVG Free... or if you must have a trojan Cleaner.. check out The Cleaner by MooSoft.

As as closing ports.... like everyone has said find out the application that is opening the port and kill it if you don't need it.. Ports don't just open, there's always a piece of software beind it... Irongeek mentioned netport... I prefer fport.. it's a very handy console app to have around. Download Here
