Random Black Box Pop-Ups in Chrome with Shady Installed Extension

    Hi guys!

    I have recently had these random box boxes pop up on chrome while surfing random sites. I realized that my ad-blocker was blocking the ads. I then realized my Bit Defender was on Game Mode for the last week, which might have let a few bugs through.

    I went into my Chrome extensions and noticed that a program, offermosquito, was installed by a third party. I uninstalled it, and yet to have any pop ups.

    Nevertheless, I was still freaked out that it was installed without my permission and suspect a malware came through. So I decided to follow the instructions on this site.

    Here are my logs, however, MGtools.exe keeps hanging at nwktst.bat during the checking local loopback ping. I've closed all programs and re-ran it. I also started Windows 7 in safe mode with networking, and still have the same problem. Does anyone know why this keeps happening?

    Thank you for any help! :)

    Welcome to Major Geeks!​
    Uninstall the below very old versions of software:
    Java 2 Runtime Environment, SE v1.4.1_07
    Java(TM) 6 Update 21

    Now install the current version of Sun Java from: Sun Java Runtime Environment

    Please download OTM by Old Timer and save it to your Desktop.
    • Run it by double clicking on it (Note: if using Vista, Win7, or Win8, don't double click, use right click and select Run As Administrator).
    • Copy the lines from the below codebox to the clipboard by highlighting ALL of them and pressing CTRL + C
      (or, after highlighting, right-click and choose Copy): Do not include the word Code: which is just a title line of
      the code box
    Code:
    :Processes
    explorer.exe
     
    :Files
    C:\Users\ronin\AppData\Roaming\SSync\SSync.exe
    C:\Users\ronin\AppData\Roaming\SCheck\SCheck.exe
    C:\Users\ronin\AppData\Roaming\DataMgr\DataMgr.exe
    C:\Users\ronin\AppData\Roaming\Intermediate\Intermediate.exe
    C:\Windows\TEMP\*.*
    C:\Users\ronin\AppData\Local\Temp\*.*

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
    "SSync"=-
    "SCheck"=-
    "DataMgr"=-
    "Intermediate"=-
    
    [HKEY_USERS\S-1-5-21-1513989743-739564920-3087322692-1000\Software\Microsoft\Windows\CurrentVersion\run]

    "Tabs"="res://ieframe.dll/tabswelcome.htm"
    :Commands
    [purity]
    [EmptyTemp]
    [start explorer]
    [Reboot]
    • Return to OTM, right click in the Paste List of Files/Folders to Move window (under the yellow bar
      ) and choose Paste.
    • Now click the large http://forums.majorgeeks.com/chaslang/images/MoveIt!.png button.
    • If OTM asks to reboot your computer, allow it to do so. The report should appear in Notepad after the reboot.
    • Close OTM.
    Now navigate to the C:\_OTM\MovedFiles folder ( assuming your Windows drive is C). This is where your log will be
    saved in the form of Date and Time mmddyyyy_hhmmss.log. Just look for the most recent .log file. Attach
    this log file to your next message.

    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.

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

    Then attach the below logs:
    • the C:\_OTM\MovedFiles log
    • the JRT.TXTlog
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    Hi!

    Thanks for the reply!

    I've done what you said, but still having problems with MGtools hanging at nwktst.bat during the checking local loopback ping. Not sure what to do? I'll still attach it's logs.

    Btw, do I have to change my passwords for my email and bank account with any malware I had in my system?

    Unless you are having other problems, I will not waste time debugging it. It could be that you are blocking ping.exe somewhere in your protection software which does not allow it to run. So are you having any other problems?

    This was just a adware type infection. It is not a information/password stealer, but it inever hurts to periodically change passwords anyway. ;)

    No, I am not having any other problems. So am I all set? Should I turn UAC back on?

    Btw, thank you so much for taking the time to help me out! That's really sweet of you!

    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. Go back to step 4 oof the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    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 or Win 7, 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. 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 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 6 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    8. After doing the above, you should work thru the below link:
