Hi guys,

I'm hoping someone here can help me.

I've recently contracted a nasty trojan called tr.kazy.mekml.1 according to Avira Antivir. It has deleted or hidded my quicklaunch icons, and most of the programs in the start menu, as well as blocking access to task manager and other useful programs. It has also deleted some icons from my desktop, as well as some important folders I stupidly left there and didn't back up.

If anyone can help me get them back I'd be very grateful. I have a system restore point for two days ago, and I'd like to make sure my PC is clean before I use it (if restoring is still possible).

Thanks in advance,

Will L

Hello as we don't know your OS yet. Please run this as it may clear it all up for us anyway.

>>>> Download this file and doubleclick on it to run it. Allow the information to be merged with the registry.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks boopme, I'm running Vista 64

I'd actually started this process already, but without stopping Avira Antivir before running Rkill. Is it important that I do so? I'll make sure to post my logs when Malwarebytes finishes its scan.

EDIT: the trojan hasn't actually deleted anything thankfully. It looks as though it's making use of Windows' hidden files option to make it look that way.

Anyway, I'll post back with my logs later

17.This infection family will also hide all the files on your computer from being seen. To make your files visible again, please download the following program to your desktop:

Unhide.exe

Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.

Thanks for the help :)

I eventaully managed to get rid of everything using a combo of spybot, malwarebytes and avira.

I'm not sure if this is the right subforum to be asking this, but is there anyway to partially undo Unhide.exe? It certainly duid what it said on the tin, but now everything is unhidden. Would a repair install of Windows do the job?

Thanks,

Will L
