Hi All,

My laptop had some unwanted pop-ups from FireFox so I scanned the whole system using McAfee and it found bunch of virus, all of which were said to be either cleaned or deleted by McAfee. I then rescanned it few times afterward and each time I get the following:

Name is "NtQueryDirectoryFile"
Detected As "Generic Rootkit.d!rootkit"
Detection Type "Trojan".

McAfee always says it is "cleaned" but it shows up each scan.

I would appreciate it if someone could help me clean it. Thanks in advance!

Hi and welcome to BleepingComputer :thumbsup:

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Hi Rigel,

Thank you for looking at my issue.

Well, things had gone from bad to really worse. I downloaded the Malwarebytes this morning and it bombed out during installation, complaining about certain "run time error 440". I then tried to reboot my machine. I chose "apply update before shut down" option because I noticed there was an update notice icon at the lower right hand corner. The machine did power down. However, when I rebooted it and right after the window screen, before the login window, I got an error message saying "service.exe cannot perform a write to certain memory location". It just hangs there. I could, however, boot into safe mode.

I am about to throw in my towels and do a fresh build, unless you tell me my OS can still be rescue.

Thanks,

Bill

All rootkit infections are bad. They attack the very core of the OS. We can try a few things, or you can reformat and reload.

An option for safe mode:

Please download ATF Cleaner by Atribune & save it to your desktop.
alternate download link DO NOT use yet.

Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the
    definitions before scanning by selecting "Check for Updates". (If you encounter
    any problems while downloading the updates, manually download them from
    here and
    unzip into the program's folder.
    )
  • Under the "Configuration and Preferences", click the Preferences... button.
  • Click the "General and Startup" tab, and under
    Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner
    Options
    , make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose:
    Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp"

ATF-Cleaner must be "Run as an Administrator".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
Let me know what version of windows you are running.

Hi Rigel,

I went ahead and tried to re-install the services.exe back and was able to re-login back in Windows (normal) again. However, when I tried to install SUPERAntiSpyware and it complained about about "Window Installer is not correctly installed". I couldn't install it in Safe Mode either, when I rebooted it Safe Mode.

I think at this point I will just go ahead and reload the OS.

Thank you very much for your help. What is really upsetting is that I still have no glue as I how got this virus in the first place.

Cheers,

Bill.

P.S. I was using Windows XP Professional SP3

Hi Rigel,

I am using another machine now.

I have used couple of portable USB harddrive as backups for the laptop and it's highly likely that they may carry the virus as well. Should I scan them using Malwarebytes o SUPERAntiSpyware to scan them from a good machine? What do I need to do to ensure they wouldn't infect the good machine?

Thanks,

Bill

That depends on the infection. With Generic rootkits, I can't guarantee any protection 100%

The best chance of protecting yourself is to have Windows fully updated - to have your anti-virus fully updated - to have a fiewall in place and functional. Make sure you scan with Antivirus and Antimalware programs (SuperAntiSpyware and Malwarebytes)
