    what's that phrase ? "you play with fire, you get burned"

    na.. so what trojan was it ? couldn't you just google the name and visit an antivirus site and try a manual removal ? how about putting in your OS cd, boot off of it and doing a restore ?
    I'm assuming you have another computer or you probably wouldn't of made it here..

    and we kinda need a bit more info from you in order to help.. which OS ? which trojan ? would help for starters.

    edit : one thing that has helped me in the past when regedit wouldn't start..

    I slaved the bad drive, scanned and cleaned it and then edited the system.ini file
    and where it normally says..

    shell=Explorer.exe

    change that to

    shell=regedit.exe

    you will then boot up and right into your registry editor where you can make your changes to need.. then of course you have to change your system.ini entry back to Explorer.exe

    This my friends (or fellow fools) is a perfect example of a script kiddie, and why you don't want to be like them. Why would you install a trojan on your computer? That's like me saying "Hey, I installed a rootkit on my server, and I got hacked." or in ratman's case "Hey, I give root access to everyone on my computer, and it got hacked, help me". You just don't do stuff like that. Also, speaking atleast a bit better (No one is perfect) might help you out a bit.)

    As for fixing it, what OS are you using? Have you tried a recovery from the install CD?

    Peace

    Unless you know what the trojan does do not install it, especially the server. That's what it's designed to do. Hide itself from running processes, change registry settings, and kill your other security measures such as AV and firewall.

    Since there are hundreds of trojans out there, I could not tell you how to get rid of it. I would try tlsecurity to see if they list it and how it works.

    You had it coming if you chose to be a tard.

    Windows XP users
    Click Start, and then click Run.
    Type command, and then press Enter. (A DOS window opens.)
    Type the following:

    cd\
    cd \windows

    Press Enter after typing each one.

    Proceed to step C of this section.


    Type copy regedit.exe regedit.com

    and then press Enter.


    Type start regedit.com

    and then press Enter. (The Registry Editor opens in front of the DOS window.)

    After you finish editing the registry, exit the Registry Editor, and then exit the DOS window as well.
    btw. where can i get the server??
    do you have the client or how does it work?
    you have a lot of trouble so it should have some use for the community

    plz tell us about the optix !!
    thx

    I play around with trojans all the time...keeps me in the know. But I sure as hell dont put it on the pc that I use for everything else!

    If you're going to play with stuff like viruses and trojans for their "educational value" (and there is educational value if they are used in the correct context) You need a special setup.

    I use several boxes of varying OSes on a seperate lan connected by double pix firewalls and a proxy to my home network. The lab network has no direct internet connectivity, and the only way to access it is either through the proxy or by simulated dial-in, for which I use a dedicated machine that is wiped after every session.

    If you can't do it right, you have no business doing it.

    What I would do is wipe the entire disk and do a clean install. but before you do that I hope that you made backups of all important data before you decided to toy around with the virus And for future testing I would use a spare machine that you don't use that often and doesn't matter if you have to reinstall the O.S over and over again and another smart idea is to keep it off the internet.
