    first i need to say, i tried to help the honeynet project collecting some malware with mwcollect (www.mwcollect.org). As i am behind a router, exploiting worms cant reach me, so i forwarded the ports. Problem is : i run Windows, so the worm can exploit me. And since i didnt already run the mwcollect, i think some worm exploitet my machine.

    here's my autostart list :

    Have you tried the steps here: General Cleaning Instructions?
    As soon as you forward anything through the router you may be exposing or placing systems behind it at risk. Keep in mind that utilities used to monitor certain ports can only bind to ports not already in use, so anything already being held open by a service/application on systems behind the router are vulnerable unless firewalled on the systems themselves.

    Regards,

    Mwcollect is designed to be run on Linux, not Windows, and to simulate Windows vulnerabilities in a safe environment where they can not be maliciously exploited.

    I've run mwcollect, and the similar nepenthes, and from my logs I see a successful exploitation approximately every 20 mins. Forwarding packets to these vulnerable ports on a Windows machine won't necessarily result in a successful exploitation as many of them are based on old vulnerabilities that will be patched on a Windows XP machine that is currently up to date. Was your machine fully patched before you forwarded ports from your router?

    You could try this first... download IRClean from Diamond Computer Systems. VERY small, standalone, fast

    http://www.diamondcs.com.au/index.php?page=irclean

    It should indicate if you do have it and can maybe get rid of it.... and maybe then if that fails go to the procedures outlined in CM's post.

    TAS

    edit: PS ~ when is scans and it finds nothing, it simply closes, no 'You are Clean' type of window comes up, so don't worry. Only start worrying if it stays open with file/s listed. :(
