    Greg, remove the 'dirty' DNS cache, and restore MS's Hosts File:

    Copy and paste these lines in Note pad.

    @Echo on
    pushd\windows\system32\drivers\etc
    attrib -h -s -r hosts
    echo 127.0.0.1 localhost>HOSTS
    attrib +r +h +s hosts
    popd
    ipconfig /release
    ipconfig /renew
    ipconfig /flushdns
    netsh winsock reset all
    netsh int ip reset all
    shutdown -r -t 1
    del %0


    Save as flush.bat to your desktop.
    Double click on the flush.bat file to run it.Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

    Next, download TFC by Old Timer TFC - Temp File Cleaner by OldTimer - Geeks to Go Forums and save it to your desktop.
    Save any unsaved work. TFC will close ALL open programs including your browser!
    Double-click on TFC.exe to run it. If you are using Vista/Windows 7 right-click on the file and choose Run As Administrator.
    Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
    Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

    After doing all of the above, scan the machine with ESET OnlineScan:

    1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
      ESET OnlineScan
    2. Click the button.
    3. For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
      1. Click on to download the ESET Smart Installer. Save it to your desktop.
      2. Double click on the icon on your desktop.
    4. Check
    5. Click the button.
    6. Accept any security warnings from your browser.
    7. Check
    8. Push the Start button.
    9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
    10. When the scan completes, push
    11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
    12. Push the button.
    13. Push

    TeamViewer won't reconnect after disconnecting during Old Timer cleaning. Will have to wait to finish the steps. I did notice I cannot access Device Manager by rightclicking Computer any longer. I get a lost path when I click Manage. I had to use Control Panel.

    This reminds me why I always end up reinstalling after one of these. When I get back there next week I'll probably reapply an image from February. At least he's able to use it no problem now.

    I think the better idea of cleaning and re-installing will be for the best. Some System Check <-- fake Av will be bundled with the latest TDL rootkit.

    Everything completed without problems and performance is good.

    The only remainder experienced so far is that it's lost its path from rightclick>Computer to Management console. I wonder if that would have been one of the links restored by the brilliant Unhide program had CCleaner not deleted Temp files before it was run? It prompted that without the Temp files it could not restore other links in All Programs folder.

    May I ask what all flush.bat flushed?

    Thanks, Jacee. Would rep you again if it would let me.

    The 'flush.bat' flushed the bad DNS cache, restored MS's Hosts file, reset the winsock (in case a bad program/file hijacked it), and renewed the computers IP address.

    A request flows in the following order:
    Web browser or other application
    |
    winsock.dll
    |
    TCP/IP layers
    |
    Modem or network card
    |
    The Internet and destination

    This might also interest you DNS (Domain Name System)

    FYI: With rogues that make it appear that files/programs are missing, do not run a temp file cleaner. The rogues generally "hide" the files in the %Temp%\Smtmp folder.

    Grinler also created some scripts to restore the default Start Menu for specific versions of Windows that he has access to. See the 11/14/2011 update at Unhide.exe - A introduction as to what this program does

    Hi, Corrine. I had run CCleaner earlier after infection so Unhide couldn't restore the Start Menu items.

    This was a learning experience.

    Hi, Greg. I understand that. :) The purpose of my comment was twofold. First to advise others who may read this topic not to run a temp file cleaner and, second, to direct your attention to are Grinler's scripts to restore the Start Menu items. They are in the same discussion topic as the information on Unhide.exe. Just scroll down the page to the section marked Update 11/14/2011.

    Thanks, Corrine. :)

    Unhide is a lifesaver. The guy's external had almost 1tb files which were hidden and it unhid them as well as all of his data flawlessly.

    Zepher's advice to unhide them in Control Panel>Folder options worked initially but I needed a permanent solution so I could rehide legitimately Hidden Files.

    It is even more of a lifesaver now! Grinler posted this update to the Unhide.exe topic today:

    Update: 04/03/2012

    Unhide was updated to include certain Start Menu options that were being hidden on the start menu. Unhide will now restore those settings back to Windows defaults and then restart Explorer.exe so that the changes go into effect.

    These start menu items that are now made visible include:

    • Documents
    • Pictures
    • User Profile
    • Music
    • Games
    • Control Panel
    • Videos
    • Default Programs
