  1. Very new to all of this. But I have followed the previous steps and ran hyjacker and malwarebytes. I am unable to run combofix, it pops up the blue box and then when I try to enter the 1 it closes up completely. Also, when clicking remove all on malware I was prompted that some could not be deleted and would need to be restarted to delete.

    I like many other people managed to infect my system with some nasty spyware detailed below are the ones causing problems:


    It is a White and Blue window that says 'Security system Waring"

    A red box mentioning something like:

    Alert Details
    File: C:\WINDOWS\wml.exe


    3) Warning: Your computer may have critical errors in Windows registry and file system!

    and 4) Yellow Triangle with exclamation mark in the bottom right corner where the clock is located. Its constantly prompting me there is spyware infecting my system and is directing me to a website to download some spyware remover.

    Along with many other issues, such as taking me directly to a page for buying spyware removal. I have tried several things such as ad-ware and no such luck.

    If some could please help me fix this problem i would greatly appreciate it.

    I am running on Windows XP

    OK. First of all only use internet explorer if you absolutely have to: Here are 2 more secure browsers to choose from
    1)Firefox ->
    2)Opera ->

    Update your Java Runtime Environment
    • First try going to Start -> Control Panel -> double click Java
    • Select the Update Tab at the top of the Java console
    • Click the Check for Updates button at the bottom
    • If it finds the newer version (Java 6 Update 5) Follow the on screen instructions
    • After it installs the newest version Go back to Control Panel -> Add/remove programs
    • Uninstall any older versions of Java

    If for some reason you couldn't update through the above instructions.
    • Click the following link
      Java Runtime Environment 6 Update 5
    • The 4th option down is the one you want (click Download)
    • Check the box to agree to terms of service
    • Check the box for your operating system and click 'Download selected'at the bottom
    • After the install Go to Start-> Control Panel-> add/remove programs (Programs and features), and uninstall any old versions
    • Navigate to C:\programfiles\Java -> delete any subfolders except the jre1.6.0_05 folder

    Download and Install SDFix
    • Download SDFix and save it to your Desktop.
    • Double click SDFix.exe and it will extract the files to %systemdrive%
      (Drive that contains the Windows Directory, typically C:\SDFix)

    Run SDFix
    • Open the extracted SDFix folder and double click RunThis.bat to start the script.
    • Type Y to begin the cleanup process.
    • It will remove any Trojan Services and Registry Entries that it finds then prompt you to press any key to Reboot.
    • Press any Key and it will restart the PC.
    • When the PC restarts the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
    • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt
    • Attach Report.txt back here

    • Download Combofix to your desktop.
    • Double click combofix.exe & follow the prompts.
    • A window will open with a warning.
    • Type "1" (and Enter) to start the fix.
    • When the scan completes it will open a text window. Please attach that log back here together with a fresh HJT log.
    Caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop. Combofix is a very powerful tool so please do NOT do anything without instruction

    Combofix will automatically save the log file to C:\combofix.txt

    After the scans

    Ok here are the new scans. I followed all of the steps from the java to sdfix to combofix. I still have the pop ups and internet explorer keeps opening on it's own even though I was using firefox. Thanks for the help.

    Hi Andrea, just had a look at your posts and your reports there. I see you have been downloading games and things from zango, that is where your problems are coming from.
    If you go to control panel, look through the list and anything from zango uninstall, also look for programmes with "ad" or spam remover etc in their title, if you are unsure what to download, take a pic of your programmes in the control panel and post it on here, also remember to run your spyware again, mcafee etc all good but if you have accepted a programme which is downloading this then it will not necessarily pick up on it. We have all done it at some point and it is not the end of the world so would not worry about it.
    Post back if you found anything in your installed programmes, if you are unsure of anything do not remove it but ask about it on here.

    Thanks I will try that...however, the odd part is that I have never been to zango and don't download stuff...unless it came from something on facebook I have no idea. Thanks for the help.

    try downloading and running avg antispyware 7.5, it is free or you can download the full version on a 30 days trial for free as well. This will remove the zlob downloader ( one that is coming through or as zango for you ).

    Also, when you are running your virus scans and any anti spy scans, remember to do so in safe mode and try not to access the net at the same time, when your scans have run, and if everything is cleared, ( check with a couple of different anti spy etc ) set a new clean restore point for yourself to go back to.

    The thread starter has the full Mcafee protection already installed, and though I am not a fan of Mcafee we do not recommend installing another anti-virus program in addition to the current protection. You can have all the anti-spyware programs you want but 1 anti virus and 1 firewall

    Super Anti Log

    Ok here is the scan for the last step I have followed with the SuperAntiSpyware. Still having pop ups but it appears that the trojans showed up on this scan...even for slow people like me! I really do appreciate all of this help.

    Now copy

    and Paste into notepad. Select Save As, set Notepad to 'All Files' and save the file as FixReg.REG. If you save it on your desktop it will be easy to find.

    Double-Click on the file; FixReg.REG and allow the contents to be merged into the Registry (click 'Yes' when asked)..


    Open notepad and copy/paste the text in the code box below into it:
    NOTE* make sure to only highlight and copy what is inside the quote box nothing out side of it.
    Also ..

    Pay particular attention to this :-

    Make sure the word File:: is on the first line of the text file you save (no blank line above it, & no space in front of it)
    Save this as CFScript.txt

    Then drag the CFScript.txt into ComboFix.exe as you see in the screenshot below.


    This will start ComboFix again. After reboot, (in case it asks to reboot), post the contents of Combofix.txt in your next reply together with a fresh HJT log.

    New logs of combofix

    Ok I followed the previous steps and ran combofix again with a new HJT log. The pop ups dissappeared from the screen and the screen background that said your computer has been infected with spyware. So looks like progress!

    Thanks so much. The computer is running much better. No popups and it is amazing to have control over my own computer being able to close programs, ctrl alt delete for intstance.

    When I follow the previous directions and go to command prompt I get an error message that says SC open service failed 1060: The specified service does not exist as an installed service.

    Looks good.

    Launch MBAM -> select quarantine tab -> highlight all infection and select delete all

    Uninstall Combofix
    * Click START then RUN
    * Now type Combofix /u in the runbox
    * Make sure there's a space between Combofix and /u
    * Then hit Enter.

    * The above procedure will:
    * Delete the following:
    * ComboFix and its associated files and folders.
    * Reset the clock settings.
    * Hide file extensions, if required.
    * Hide System/Hidden files, if required.
    * Set a new, clean Restore Point.

    Cleanup using OTMoveit2 by OldTimer
    Now we can clear out the rest of the programs we've been using to clean up your computer, they are not suitable for general malware removal and could cause damage if launched accidentally.

    Download OTMoveIt2 by OldTimer OTMoveIt2.exe and place it on your desktop.

    1. Double click OTMoveIt2.exe to launch it.
    If using Vista Right-Click OTMoveIt and choose Run As Administrator
    2. Click on the CleanUp! button.
    3. OTMoveIt2 will download a list from the Internet, if your firewall or other defensive programs alerts you, allow it access.
    4. Click YES at the next prompt (list downloaded, Do you want to begin cleanup process?)

    * When finished exit out of OTMoveIt2

    I recommend you keep
    1 anti virus program
    1 firewall
    Combo of Anti-Spyware (Spybot S&D and MBAM, or your choice)

    For Spybot you can download the latest version from HERE.

    keep them updated.

    You can also turn on tea timer in Spybot:
    • Click on Mode at the top and make sure that Advanced is checked
    • Expand the Tools tab in the left pane
    • Single click on the Resident Icon also in the left pane
    • check Resident "TeaTimer" (Protection of over-all system settings) Active
    • Close spybot

    Also under Tools you can double-click System Startup in the right pane and disable programs from running at startup. This will free up system resources. For example if you don't use MSN Messenger everytime you run your computer you can disable it, then when you want to use it you can launch it through Start -> all programs, or make a shortcut on the desktop for it. That way it doesn't use resources when you aren't using it. Don't disable any entries in green though.

    And just to be sure
    Set correct settings for files
    • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
    • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
    • If unchecked please check Hide protected operating system files (Recommended)
    • If necessary check "Display content of system folders"
    • If necessary Uncheck Hide file extensions for known file types.
    • Click OK

    clear system restore points

    • This is a good time to clear your existing system restore points and establish a new clean restore point:
      • Go to Start > All Programs > Accessories > System Tools > System Restore
      • Select Create a restore point, and Ok it.
      • Next, go to Start > Run and type in cleanmgr
      • Select the More options tab
      • Choose the option to clean up system restore and OK it.
      This will remove all restore points except the new one you just created.
