I should start with the fact that I am not so computer savvy. So anyways, I am using a friend's computer and I think I have downloaded something I shouldn't have. I am pretty sure I am using Windows XP, and I primarily use firefox. I am getting numerous messages that have a variety of different titles that all end with .exe - Bad Image (ex: LuCallbackProxy.exe - Bad Image). The error message says: The application or DLL c:\windows\systems32\dukotova.dll is not a valid Windows image. Please check this against your instillation diskette. I get this message multiple times before the computer is fully loaded, and then about every 3 minutes. I have run Norton antivirus, Windows defender full scan and Spybot Search and Destroy and it hasn't seemed to fixed anything. I am really worried I can't fix this. Any help would be REALLY appreciated! please help me fix this before I have to give the computer back!

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Now run the Full Scan and post the new log.

so far the pop-up thing hasn't come back which is awesome!! and the scan said no malicious items found. Thank you soo much! just a question, is this scan thing something i should be doing often by myself, or is it only something I should do when I have someone to interpret the results? I'm sorry if that sounds stupid

You can run the scan yourself any time you feel the need.

If you’re clean, you should create a new Restore Point to prevent possible re-infection from an old one.

Go Start > Programs > Accessories > System Tools and click System Restore. Choose the radio button marked Create a Restore Point on the first screen then click Next. Give the Restore Point a name and then click Create. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go Start > Run and type: "Cleanmgr" (without the quotes). Click Ok > More Options tab > Clean Up in the System Restore section to remove all previous restore points except the newly created one.

Also, go Start > Control Panel and double-click Add or Remove Programs. Post back and report any Java entries that you have.

so I'm not 100% sure what you mean by java applications, but I think this is what you mean:

J2SE Runtime Environment 5.0 Update 11
J2SE Runtime Environment 5.0 Update 6
J2SE Runtime Environment 5.0 Update 9
Java ™SE runtime Environment 6 update 1

Those are the only things with the little java teacup icon next to them, is that what you were talking about?

Those are all out of date. You should remove them all and download the latest from here:
