Hi, I am new here. I have little knowledge of port/tcp-ip, etc, so it is difficult to interpret a firewall output. XP Pro sp3 Eset Smart Security 3 Malwarebytes ADLS, Nat router: IP 192.168.11.1, PC IP 192.168.11.2 Issue: When I use utorrent.exe, the pc freezes. utorrent connection are not affected, but I have a load of connections that seem not related to utorrent.exe (case of no download and very little upload). I guess someone is using my DSL connection through utorrent.exe (?) AV checks are negative, combofix: negative. When I stop utorrent.exe, all comes back to normal. What could it be? It is like a plague. Here are the system message: http://img152.imageshack.us/img152/5494/aaaaasg1.png Here is the ESET FW log for the current day: http://img104.imageshack.us/img104/6276/91982589fn0.png PS: how to I show the photos in the message? I tag the links with but they show up as hyperlinks?? ***************UPDATE****************** I found the answer there: http://forum.utorrent.com/viewtopic.php?id=34527 It is fixed now, not even an attack, I guess too many connections where transfered to ekrn.exe for analyze and that froze everything (what stupid advanced settings to solve the problem?! as if nobody where using utorrent..., could be a default setting "user uses torrent"). but what about the firewall log? is it normal? I have read in another thread DNS poisoning attacks where not relevant. So what to believe now? For a first time with ESET, it is a kind of a cold shower in winter.
