    Hello MG experts,

    I have become infected with this Trojan.MSIL.Citron.hx, I went to install MorphVOX I downloaded via newsgroups, my AV (Vipre) immediately reported as trojan and attempted to quarantine. This happened yesterday.

    Symptoms before running read me - Vipre was disabled (could not invoke a scan even in safe mode), Malwarebytes was disabled, the installer window for MorphVox would appear everytime PC rebooted. Still have internet access, everything else appears fine.

    I was able to run all scans apart from Malwarebytes - tried to re-install but was unsuccessful (had this installed already before the infection)

    I had to run rogue killer again after completing the readme as the original log txt it created was empty?

    Thanks in advance for your help.

    Welcome to Major Geeks!

    Run Hitman Pro again and activate the 30 day free trial. Have it fix all the Malware and Potential Unwanted Programs that it finds. Then reboot the PC and run a new Hitman Scan and attach the new log.


    Now please download Junkware Removal Tool to your desktop.
    • Shut down your protection software now to avoid potential conflicts.
    • Run the tool by double-clicking it. If you are using Windows Vista or Seven, right-mouse click it and select Run as Administrator.
    • The tool will open and start scanning your system.
    • Note: That JRT may reset your home page to a google default so you will need to restore your home page setting if this happens.
    • Please be patient as this can take a while to complete depending on your system's specifications.
    • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
    • Attach JRT.txt to your next message.
    Then attach the below logs:
    • the Hitman Prolog
    • the JRT.TXT log
    Make sure you tell me how things are working now!

    Hello Chaslang,

    Thank you for taking the time to read through my log files and respond, much appreciated.

    I have followed your instructions and attached the logs you requested.

    My AV (Vipre) is still being blocked / denied from starting when I boot windows, when attempting to run it from the start menu I get the following error message:

    "The Vipre service is not running. If this continues please contact Technical Support."

    I should have mentioned in my first post that the installer window for MorphVOX disappeared from boot up once I had completed the read me scans.

    Thanks again

    You're welcome.

    I suggest that you try uninstalling it and then reboot your PC. After reboot, reinstall and see if it works okay.

    I'm sure that you probably noticed by now that the forum software was changed since last night. It is apparent that we have lost a few posts from last night.
    So I don't know if you ever saw my last fixes using FRST and also a couple of your last posts are now missing. Can you please reattach the last logs I had you create last night. These were at a minimum the scan results from running FRST and also a new MGlogs.zip file. I don't really need the results from having run Hitman Pro again since we know that it had not fixed the problem. I can reattach the proposed fix with FRST if you missed it. Just let me know if you need it.

    good morning and yes, I had a WTF moment when i check back here :eek:
    so I completed the instructions that you had posted and I had replied, so I will do my best at remembering what I wrote.....

    Attached is the fixlog.txt and I couldn't attach the MGlogs.zip (file type unsupported?) so i renamed the extension to .txt - hopefully you can just rename it to a .zip and it works? if not let me know I can post the individual .txt files for you

    I was able to manually delete the vipre folder in c:\program files(x86), the two items on my desktop (shortcut to malwarebytes & roguekiller.exe) still cant be deleted - permission required?

    Malwarebytes (that was already installed before the infection) will now run (this was previously blocked) - I didnt run a scan (the database was outdated anyway and cant update it).

    The infected PC can no longer access the internet, it has an error about the "wired network adapter having problems" - the router is working fine as this computer I am using to post here has no problems with it.
    I also forgot to mention with the windows repair, the option to repair winsock & DNS cache (i think) was available, but all others repairs were done.

    Thanks again for your help with this

    You're welcome.
    Let's try to fix the networking issue and also I will give you a new version fix for Windows Repair since the program has changed. But first, if you have not powered down the PC since running the previous fix then please power the PC down for a few minutes. Then power back up and continue. If you had already powered down last night then just continue on.

    • Now run Repair_Windows.exe by double clicking on it ( if you are running Vista or Win 7, use right click and select Run As Administrator)
    • Now select the + Repairs tab.
    • Then click the + Open Repairs button down on the bottom right.
    • This will automatically begin a registry backup, so wait for it to complete and when it finishes, you will see a list of many possible different repairs and they are all selected by default. At the bottom of this form there is a not so obvious Unselect All Repairs check box which is to the right of a check box with a green check mark in it. Please click the Unselect All Repairs box. The green check mark box is to Select All Repairs. The ony way you see what these boxes are is when your mouse hovers over them.
    • Now select the following repair options ( the numbers at the begin are the current repair numbers but this is subject to change.)
      • 01 - Reset Registry Permissions
      • 02 - Reset File Permissions
      • 03 - Reset Service Permissions
      • 04 - Register System Files
      • 05 - Repair WMI
      • 06 - Repair Windows Firewall
      • 10 - Remove Policies Set By Infections
      • 13 - Network
      • 14 - Repair Proxy Settings
      • 15 - Repair Windows Updates
      • 21 - Repair MSI (Windows Installer)
      • 23 - Repair File Associations (12 )
      • 26 - Restore Important Windows Services
      • 27 - Set Windows Services To Default Startup
    • Now on the right side under the When Repairs Complete title, check the box for Restart/Shutdown System and then make sure the Restart System radio button is enabled not the Shutdown System button.
    • Shutdown any other programs that you are running now before continuing.
    • Now click the Start Repairs button at the lower right.
    • Be patient while the tool repairs the selected items.
    • It should reboot automatically when finished. If it does not then reboot it yourself.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, Win7, or Win8, don't double click, use right click and select Run As Administrator).
    Then attach the below logs:
    • C:\MGlogs.zip

    Also after attaching the above log, please run a new scan with FRST just like you did previously and attach the new log. Since the instructions are missing from the thread, I will repost them. You don't need to redownload FRST since you already have it. I'm just reposting the complete instructions.

    Please do the below so that we can boot to System Recovery Options to run a scan.
    For 32-bit (x86) systems download Farbar Recovery Scan Tool and save it to a flash drive.
    For 64-bit (x64) systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

    Plug the flashdrive into the infected PC.
    Enter System Recovery Options from the Advanced Boot Options:
    • Restart the computer.
    • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
    • Use the arrow keys to select the Repair your computer menu item.
    • Select US as the keyboard language settings, and then click Next.
    • Select the operating system you want to repair, and then click Next.
    • Select your user account an click Next.

    On the System Recovery Options menu you will get the following options:
    • Select Command Prompt
    • In the command window type in notepad and press Enter.
    • The notepad opens. Under File menu select Open.
    • Select "Computer" and find your flash drive letter and close the notepad.
    • In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
      Note:
      Replace letter e with the drive letter of your flash drive.
    • The tool will start to run.
    • When the tool opens click Yes to disclaimer.
    • Press Scan button.
    • It will make a log (FRST.txt) on the flash drive. Please attach this file to your next reply. (See: How to attach)


    Now please download Farbar Service Scanner and run it on the computer with the issue.
    • Put a check mark in each option box on the left side.
    • Click "Scan".
    • It will create a log (FSS.txt) in the same directory the tool is run.
    • Please attach this log to your next reply.

    I have run the windows repair again (twice in safe mode), this doesn't appear to have repaired the networking issue :( - other symptoms appear the same.

    The remainder of your instructions have been followed and the log files you requested have been attached (again I renamed the MGlogs.zip to .txt).

    thanks

    A DLL file for Windows Live is missing which has broken your LSP chain and this will in turn cause no network access. We will remove this from your LSP chain to see if that fixes the problem. If you need Windows Live, you may need to reinstall but I don't see it even installed.

    You don't need to do this. You only had to do it previously because you were reattaching the same log a 2nd time due to the forum change to new software.

    Now download LSP - Fix

    Run LSP-Fix.

    Check the Box labeled "I know what I'm doing" and then click on the wlidnsp.dll file (in the “Keep” section) to select it.

    Then, Select the >> button to move wlidnsp.dll into the Remove section.

    Now, click the Finish Button. When the Repair Summary box appears, click OK.
    If it is already in the Remove section, just click Finish.

    Now reboot your PC and see if there is any change.

    Okay it may be necessary to reinstall your network card drivers because no network cards were showing up in your previous log. You probably show errors in Device Manager for your network interface card. Do you have the driver disks for your PC?

    Burnstarr69 Private E-2

    okay, MB has onboard lan, will download latest drivers and re-install. in device manager the issues are related to sunbelt software (vipre) - screen grab attached......

    will let you know how i go

    ok, that has seemed to work, I tried repairing the LAN drivers, but didn't work so I uninstalled and re-installed and can now access the internet. Tried to uninstall the sunbelt firewall entries but still there, I ran CCleaner to clean the registry - this removed some sunbelt entries (hope this was ok) - kept a registry back up.

    HitmanPro was run again and no threats detected (log attached) - guessing this means the infection has been cleaned?

    only other symptoms are the two items on my desktop I cant delete.

    Thank you again for your hard work in getting rid of this trojan :D

    You're welcome. Sounding a lot better. Exactly which files are you referring to on your Desktop.

    Burnstarr69 Private E-2

    Yeah, glad to have this PC back online - although would like to be able to re-install vipre again, is it ok to proceed with that?

    the two files on my desktop are:
    C:\Users\Public\Desktop\Malwarebytes Anti-Malware (shortcut)
    C:\Users\Ben\Desktop\RogueKiller.exe

    when I downloaded roguekiller the first time and went to run it, it gave me a permission error and couldn't rename it - this has been there since I worked through the read me.
    Malwarebytes - I attempted to install this onto a separate drive (it was already installed on C:\ before the infection but was blocked by the trojan) - obviously this didnt work - I have since removed the remnants of that attempted install but the shortcut still remains.

    Neither of these files can be deleted or renamed, gives an error message that I need permission from NZXT_PC\Ben (roguekiller) or Administrators for the shortcut.

    I would wait on reinstalling Vipre until we are finished just to avoid any unwanted complications.

    Try right clicking on the files on your Desktop and selecting Properties. Then select the Security tab and see if you can choose your user name in the Group or user names: section and then click the Edit button to change permissions. Then on the next Permissions form, again choose your name and see if you can set the Permissions for Full control. Then apply and OK your way out. See if this helps.

    You're welcome.

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware.
    2. Renable your Disk Emulation software with Defogger if you had disabled it in step 4 of the READ & RUN ME.
    3. Go to add/remove programs and uninstall HijackThis. If you don't see it or it will not uninstall, don't worry about it. Just move on to the next step.
    4. If running Vista, Win 7 or Win 8, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    5. Now goto the C:\MGtools folder and find the MGclean.bat file. Double click ( if running Vista, Win7, or Win 8 Right Click and Run As Administrator ) on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    6. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    7. If you are running Win 8, Win 7, Vista, Windows XP or Windows ME, do the below to flush restore points:
      • Refer to the instructions for your WIndows version in this link: Disable And Enable System Restore
      • For Windows 8 and 8.1 system restore see this link: Win 8 System Restore - How to enable/disable
      • What we want you to do is to first disable System Restore to flush restore points some of which could be infected.
      • Then we want you to Enable System Restore to create a new clean Restore Point.
    8. After doing the above, you should work thru the below link:
