    Print these instructions out.

    NOTE. If any of the programs listed below refuse to run, try renaming executive file to something else; for instance, rename hijackthis.exe to scanner.exe

    ***VERY IMPORTANT! Make sure, you update Malwarebytes before running the scans.***


    STEP 1. Download Malwarebytes' Anti-Malware: Malwarebytes.org to your desktop.
    (Malwarebytes is free to use as a manual scanner. Payment is only required if you wish to have it run and update automatically which is not necessary for our purposes)

    * Double-click mbam-setup.exe and follow the prompts to install the program.
    * At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
    * If an update is found, it will download and install the latest version.
    * Once the program has loaded, select Perform Quick Scan, then click Scan.
    * When the scan is complete, click OK, then Show Results to view the results.
    * Be sure that everything is checked, and click Remove Selected.
    * When completed, a log will open in Notepad.
    * Post the log back here.

    The log can also be found here:
    C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
    Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

    RESTART COMPUTER!

    STEP 2. Download GMER: GMER - Rootkit Detector and Remover, by clicking on Download EXE button.
    Alternative downloads:
    - |MG| GMER 1.0.15.15281 Download
    - http://www.softpedia.com/get/Interne...ers/GMER.shtml
    Double click on downloaded .exe file, select Rootkit tab and click the Scan button.
    When scan is completed, click Save button, and save the results as gmer.log
    Warning ! Please, do not select the "Show all" checkbox during the scan.
    Post the log to your next reply.

    RESTART COMPUTER

    STEP 3. Download HijackThis:
    HijackThis - Trend Micro USA
    by clicking on Installer under Version 2.0.2
    [DO NOT download version 2.0.3 (beta)]
    Install, and run it.
    Post HijackThis log.
    NOTE. If you're using Vista, or 7, right click on HijackThis, and click Run as Administrator
    Do NOT attempt to "fix" anything!


    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

    I have just encounter that the virus does not let you run the application program. The 1st step cant be execute.

    1. Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.

    There are 4 different versions. If one of them won't run then download and try to run the other one.

    Vista and Win7 users need to right click Rkill and choose Run as Administrator

    You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

    * Rkill.com
    * Rkill.scr
    * Rkill.pif
    * Rkill.exe

    * Double-click on the Rkill desktop icon to run the tool.
    * If using Vista or Windows 7 right-click on it and choose Run As Administrator.
    * A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
    * If not, delete the file, then download and use the one provided in Link 2.
    * If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
    * Do not reboot until instructed.
    * If the tool does not run from any of the links provided, please let me know.

    Once you've gotten one of them to run then try to immediately run the following.

    2. Now download and Run exeHelper.

    * Please download exeHelper from Raktor to your desktop.
    * Double-click on exeHelper.com to run the fix.
    * A black window should pop up, press any key to close once the fix is completed.
    * A log file named log.txt will be created in the directory where you ran exeHelper.com
    * Attach the log.txt file to your next message.
    [/LIST]


    Note: If the window shows a message that says "Error deleting file", please re-run the program before posting a log - and post the two logs together (they will both be in the one file).

    3. Please download ComboFix from Here or Here to your Desktop.


    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**

    • Please, never rename Combofix unless instructed.
    • Close any open browsers.
    • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
    • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
    • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

    NOTE 1. If Combofix asks you to install Recovery Console, please allow it.
    NOTE 2. If Combofix asks you to update the program, always do so.


    • Close any open browsers.
    • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
    • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
    • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    • Double click on combofix.exe & follow the prompts.
    • When finished, it will produce a report for you.
    • Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review.

    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!
