    Currently, the most visible issue that I'm experiencing is an AD that seems to be injected into certain websites (my father mentioned something about Gala? Search tool), but I've also noticed the fans going off at full blast when not in use.

    Please download ComboFix to your desktop and run it. Do not do anything while it runs. Attach the log when it is finished.

    Once done, 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:

    * C:\ComboFix.txt
    * C:\MGlogs.zip

    Make sure you tell me how things are working now!

    Combofix reported that I had Microsoft Security Essentials running, but there was no tray icon for it, nor was it listed in programs and features. I could not change any settings that I could tell with Windows Defender either, so I ran Combofix anyway.

    After Combofix's log was generated, I had to reboot to use MGtools.

    The ads seem to have disappeared from the sites that previously would show them.

    Please do the below so that we can boot to System Recovery Options to run a scan. There will be two options to choose from. One if you do not have your Windows 7 boot DVD and another when you have your DVD.

    For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.
    For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

    Plug the flashdrive into the infected PC.

    Option1: 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.

    Option2: Enter System Recovery Options by using Windows installation disc:

    • Insert the installation disc.
    • Restart your computer.
    • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
    • Click Repair your computer.
    • 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 and 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)

    Fixlist.txt

    Save fixlist.txt to your flash drive.

    • You should now have both fixlist.txt and FRST.exe on your flash drive.

    Now reboot back into the System Recovery Options as you did previously.
    Run FRST and press the Fix button just once and wait.
    The tool will make a log on the flashdrive (Fixlog.txt).
    Please attach this to your next message. (See how to attach)

    Now boot into normal Windows can continue with the below.

    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:

    * Fixlist log

    Looks good.

    If you are not having any other malware problems, it is time to do our final steps:

    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real time protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.We recommend them for doing backup scans when you suspect a malware infection.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.


    3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, 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.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click 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.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 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.

    10. After doing the above, you should work thru the below link:
