    Hi all,

    I have a trojan that I can't seem to get rid of, and I need your help.

    I have NOD32 antivirus, it always capture the file and delete it, but it keeps coming back.

    the trojan name is win32/medbot.FW trojan as reported by NOD32, it always makes two files at the roots of my hard disk partitions, one is autorun.inf, the other is setup.exe, I tried erasing them manually all and restart my PC, worked for a while but they came back again. I tried searching goolge for the trojan but I didn't find any information about it. please help me to get rid of it without installing a new windows.

    thank you

    Hi virtu,
    From what you say I think you need to post a HijackThis log and then wait for someone qualified (gold shield next to their name) to take you through what needs to be done. Please go no further than the steps below and posting your results for now.You may want to print off this guide just in case.

    Using Hijackthis with the self-installer that puts it into Program Files for you:

    go to Click here to download HJTsetup.exe


    • Save HJTsetup.exe to your desktop.
    • Double click on the HJTsetup.exe icon on your desktop.
    • By default it will install to C:\Program Files\Hijack This.
    • Continue to click Next in the setup dialogue boxes until you get to the Select Additional Tasks dialogue.
    • Put a check by Create a desktop icon then click Next again.
    • Continue to follow the rest of the prompts from there.
    • At the final dialogue box click Finish and it will launch Hijack This.
    • Click on the Do a system scan and save a log file button. It will scan and then save the log and then the log will open in Notepad.
    • Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
    • Paste the log in your next reply.
    • DO NOT have Hijack This fix anything yet. Most of what it finds will be harmless or even required.

    Once you've done this, wait and you'll get great help.

    Richard.
