Hi All,
Over the weekend I was using my laptop and unfortunately I found a virus/trojan named "dna.exe" which was slowing down my computer. I did a "netstat" in the Windows XP command prompt and my laptop was trying to connect to over 100 computers. I removed this virus and the laptop is running fine.
However...
I noticed that there is a connection to port: 3158 and the IP address is 70.42.52.11 . I tried doing a trace route and unfortunately it didn't give me much information as to where is the location of this IP address is coming from. Even after I do a clean reboot, my laptop keeps connecting to that IP address and the same port.
The question I ask is port: 3158 a potential security hole or is it a safe service program that I am unaware that my laptop keeps executing?
If need anymore details, I am more than happy to provide it if there is any good Samaritan willing to assist me.
Thanks |

Re: Port 3158
The next thing to consider is do these people have any buisness connecting to you or you to them? Do they even know they are trying to connect to you? |

Manchester, NH | Port 3158 = "SmashTV Protocol", whatever that is.
But it could be a trojan as well. Is the connection inbound or outbound? Can you post the output of netstat -ano? |

If in fact you do have Trillian.....and you have used it for File Transfer...then perhaps thats were the Trojan came from, but no matter....there appears NO REASON for that particular Port to be doing anything....unless someone else here can offer a reason.......
My suggestion would be to remove Trillian if in fact you do have it installed....if its the Agent in all this then removing it should shut down that port....
Are you ABSOLUTELY SURE you removed that Trojan ? |
