Trojan/Other Virus problems

By ChrisTheCracka
Sep 4, 2006
  1. So the other day I happened to open a file containg some trojans/spyware/etc.

    I tried to scan my computer using the online scanners suggested but all my browsers keep exiting in the middle, due to the trojans...so as of right now I'm fighting a losing battle.

    I've been forced into Safe Mode with Network Settings...and right now I'm at a loss for what to do.

    Any help is greatly appreciated...

    EDIT: So now I am unable to even use my keyboard...and my account is password protected.

    Hello and welcome to Techspot.

    Go HERE and follow as many of the instructions as you can.

    Post a fresh HJT log as an attachment into this thread, only after doing the above.

    So I was able to do the Trojan Hunter scan in Safe Mode, which was about all.

    I'm really lost as to what else to do and it seems that isnotify/ismini/etc have moved into safe mode aswell.

    If you could walk me through what I need to do it would be greattttt.

    Download and run these four tools. Follow the instructions for using each tool.

    Tool1 Tool2 Tool3 Tool4

    Download and install Ewido http://www.ewido.net/en/download/
    Double-click the Ewido icon on your desktop to run it.
    On the top of the main screen click Shield. Click the word active to change it to inactive.
    On the top of the main screen click 'Update'. Then click on 'Start update'. The update will start and a progress bar will show the updates being installed.
    If you are having problems with the updater, you can get the manual update at http://download.ewido.net/ewido-signatures-full-current.exe
    When you have finished updating, exit Ewido.

    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Turn off system restore.(XP/ME only) See how here.> http://www.bleepingcomputer.com/forums/tutorial56.html

    Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how here.> http://www.bleepingcomputer.com/forums/tutorial61.html

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how here.> http://www.bleepingcomputer.com/forums/tutorial62.html

    Make sure all windows are closed. Run Ewido.
    Click 'Scanner'. Then click 'Complete System Scan' to begin scanning.
    When the scan is complete click 'Recommended Action' and change it to 'Quarantine'.
    Then click 'Apply all actions'.
    Once finished, click the 'Save report' button. Then click 'Save Report As' and save it to your desktop.

    Reboot into normal mode and turn system restore back on.

    Post the Ewido report and a fresh HJT log as attachments. See HERE for HJT instructions.

    Alright so I did all the steps and was able to remove everything but the file you said to remove using killbox(winmbj32.dll). When I run killbox it says the file cannot be deleted.
