Full Version: Help! I've been Hijacked by res://qtndi.dll/index.
Gladiator Security Forum > Malware Help Forum > HELP! Think you are Infected?
NicktheDad
My son's EI has been corrupted by this res://qtndi.dll/index.html#12802 hijack that refuses to let us redefine his homepage, gives us various annoying pop-ups (even with the Google toolbar anti-popup service engaged) and occasionally informs us that the system admin hasn't given us enough priviledge to perform some operation. I've tried both AdAware (01.07.2004 Reference file) and Spybot S&D with no good results. It seems like things are being reloaded as fast as they are exterminated. I've included my latest hijackthis output (v 1.97.7) for your analysis. Any help cleansing the system and protecting it in the future would be greatly appreciated.

Thanks,

NicktheDad

Hi NicktheDad,

Thanks for being so patient, we are quite backlogged with requests for help as you can see flowerz.gif

First, Please make a new folder to put your HijackThis.exe into. Anywhere on your hard drive is fine other than your Desktop or the Temp folder. We suggest you use C:\Program Files\HijackThis but feel free to use any name or folder you like. Unzip HijackThis again and save the contents (Hijackthis.exe) to the new folder you made. Then navigate to it and run HijackThis from there. This is to ensure it makes the necessary backups for recovery if needed.

1. Download this tool called AboutBuster http://www.downloads.subratam.org/AboutBuster.zip

Unzip it to your desktop but don't run it yet.

2. If you already have Adaware installed, just make sure it's up to date. Just open Adaware and click on *Check for Updates Now* and then *Connect*. It will find a new reference-file. Click *ok* and let it download and install the updates by clicking on *Finish* .This will return you to the main screen. You should now see Reference File # : 01R326 01.07.2004 or higher listed.

3. Print out these instructions so you have them handy as some of the steps need to be done in safe mode and you may not be able to go online.

4. Make sure your PC is configured to show hidden files

Open Windows Explorer & Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked. Also uncheck "Hide protected operating system files" and untick "hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"

5. Next, go to Start->Run and type "Services.msc" (without quotes) then hit Ok

Scroll down and find the service called "Network Security Service". When you find it, double-click on it. In the next window that opens, click the Stop button, then click on properties and under the General Tab, change the Startup Type to Disabled. Now hit Apply and then Ok and close any open windows.

6. Reboot to Safe Mode
How to start the computer in Safe mode
http://service1.symantec.com/SUPPORT/tsgen...src=sec_doc_nam

7. Scan with Hijack This and put checks next to all the following, then click "Fix Checked"

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = res://C:\WINDOWS\qtndi.dll/sp.html#12802

R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = res://qtndi.dll/index.html#12802

R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = res://qtndi.dll/index.html#12802

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = res://C:\WINDOWS\qtndi.dll/sp.html#12802

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = res://qtndi.dll/index.html#12802

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = res://C:\WINDOWS\qtndi.dll/sp.html#12802

O2 - BHO: (no name) - {F46BFBE4-74D6-8A19-EF8B-A8BBD569B571} - C:\WINDOWS\netpw32.dll

O4 - HKLM\..\Run: [ipzf32.exe] C:\WINDOWS\system32\ipzf32.exe

and delete the following files if present.

C:\WINDOWS\system32\ipzf32.exe

C:\WINDOWS\winrl.exe

C:\WINDOWS\qtndi.dll

C:\WINDOWS\netpw32.dll


8. Go to Start->Run and type Regedit then click Ok. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
and highlight Services in the left pane. In the right pane, look for any of these entries:

__NS_Service
__NS_Service_2
__NS_Service_3

If any are listed, right-click that entry in the right pane and choose Delete.

Again in Regedit, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root and highlight Root in the Left Pane. In the right pane, look for these entries (the number at the end should correspond to the first one you deleted above):

LEGACY___NS_Service
LEGACY___NS_Service_2
LEGACY___NS_Service_3

If you find it, right-click it in the right-pane and choose delete.

9. Double click AboutBuster.exe that you downloaded earlier. Click OK, click Start, then click OK. This will scan your computer for the bad files and delete them.

10. Scan with Adaware and let it remove any bad files found.

11. Clean out temporary and TIF files. Go to Start > Run and type in the box: cleanmgr. Let it scan your system for files to remove. Make sure these 3 are checked and then press *ok* to remove:

Temporary Files
Temporary Internet Files
Recycle Bin

12. Reboot to normal mode, scan again with Hijack This and post a new log here.

13. NOTE:Two, possibly 3, files were also deleted from your computer and need to be replaced.

Control.exe
hosts (with no extension)
SDHelper.dll (if you are using Spybot Search & Destroy)

If control. exe is missing
Go here: http://www.spywareinfo.com/~merijn/winfiles.html#control and download the version of control.exe for your operating system. If you are running Windows 2000, copy it to c:\winnt\system32\. For Windows XP, copy it to c:\windows\system32\.

Download the Hoster from here: http://members.aol.com/toadbee/hoster.zip
Press 'Restore Original Hosts' and press 'OK'
Exit Program.
Note: if you were using a custom Hosts file you will need to replace any of those entries yourself

If you have Spybot S&D installed and SDHelper.dll is missing, replace it here:
URL=http://www.spywareinfo.com/~merijn/winfiles.html#sdhelper]http://www.spywareinfo.com/~merijn/winfiles.html#sdhelper[/URL] and download SDHelper.dll. Copy the file to the folder containing you Spybot S&D program (normally C:\Program Files\Spybot - Search & Destroy)
........................................................
14. Additionally, Please check your ActiveX security settings. They may have been changed by this CWS variant to allow ALL ActiveX!! If they have been changed, reset your active x security settings in IE as recommended.

15. Finally, do an online scan at the following site. Let it remove any infected files found.
Trend Micro (PC-cillin) - Free on-line Scan

NicktheDad
CalamityJane,

My deepest thanks for your help in guiding me through this awful mess. The steps you recommended went nearly flawlessly. I have included a new copy of the HijackThis output to see if it looks right to you. Should there be multiple instances of some of the enties?

The Control.exe file was here, as was a couple of different host files. I re-installed spybot S&D to get the SDHelper file back.

The Trend Micro scan showed 18 Troj_agent.AU sort of files - is this expected? NAV 8.0 didn't see them at all.

I checked the ActiveX settings and they seemed OK. If you have any recommendations on how my son can use his computer without needlessly exposing us to this sort of trauma again, I'd really appreciate your advice. I've printed your "How to stop Hijackers..." post for him to memorize.

Again, thank you for your help and please let me know if anything still looks weird in the HijackThis output.

One last thing... Can I pay you for your help? How would I do that?

Sincerely,

Nick the Dad

Hi Nick! Woooo Hoooo! Looks good :victory:

Yes, it is normal for Trend-Micro to find additional infected files as a trojan - they are all from that hijacker and that is why so many steps because each program finds something that the others miss and I think you're completely clean once you have been through all of them.

I have submitted samples of this hijacker to Symantec, but it doesn't recognize them as infected like some of the other AVs do, unfortunately, unless you have a version that detects extra *adware* type programs (but his one is worse than what I call adware). Even if it detects them I'm not sure it can remove them.

Use HijackThis to checkmark and *fix checked* this item (it's a leftover orphaned entry)

O2 - BHO: (no name) - {83BDAA20-9B1F-DFEE-99E7-B23F0E432EFD} - C:\WINDOWS\sdkpq32.dll (file missing)

Now that your PC is clean, make sure all programs are running properly and then you'll need to reset your restore point in Windows XP.......why?

One of the best features of Windows ME or XP is the System Restore option, however if a malware infects a computer with this operating system it can be backed up in the System Restore folder. Therefore, clearing the restore points is necessary after malware removal.

To reset your restore points, please note that you will need to log into your computer with an account which has full administrator access. You will know if the account has administrator access because you will be able to see the System Restore tab. If the tab is missing, you are logged in under a limited account.

(winXP)

1. Turn off System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
Check Turn off System Restore.
Click Apply, and then click OK.

2. Reboot.

3. Turn ON System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
UN-Check *Turn off System Restore*.
Click Apply, and then click OK.

Next, we highly recommend you get some extra protection to prevent future infections. Here are some things you can do and some free programs to help :).

How to Stop Hijackers & Spyware Infections, And other malware too!
http://forum.gladiator-antivirus.com/index...?showtopic=9857

I also highly recommend to get the free tool, Microsoft Baseline Security Analyzer (MBSA) from Microsoft to analyze your PC security for prevention purposes.

MBSA Version 1.2 will scan for common system misconfigurations on Windows 2000, Windows XP, and Windows Server 2003 systems. This program will identify the system security weaknesses in your browser and operating system and provides easy instructions to correct them. This includes any missing critical Windows security updates, system vulnerabilities and your IE Browser security settings. Get the download here:
Microsoft Baseline Security Analyzer
http://www.microsoft.com/technet/security/...s/mbsahome.mspx

I know you already got the How to Stop Hijackers - that's got our best recommendations in it for securing IE and your PC from future attacks. You might also consider an alternative browser for your son and use IE only when needed for sites that require ActiveX and are trusted (like Windows update). I use Firefox 0.9.1 for 99% of my everyday surfing (using it right now in fact). If that were my son, I would have him use it too. It's free and very easy to setup, understand and use without many of the vulnerabilities that IE has.

We're just volunteers here, spending our time trying to help out our internet neighbors who get nailed with this junk.

CalamityJane,

You are my hero! My son's computer has been well behaved for over a week now. I have reset the system restore point as you suggested and we are using the firefox browser (I think it is substantially better than IE). I hope the feeling of satisfaction you get from rescuing folks like me is as deep as the sense of gratitude I feel for your help.

YOU ROCK!

Thanks again,

Nick the Dad
