Hi,

My daughters laptop is running Windows XP and has been acting rather strangely, playing feeds from radio stations etc. without warning.

I have installed Spyware Doctor and it has cleaned a number of viruses etc. but it appears that the laptop is infected with Rootkit.TDSS.sd6

I am trying to download WIndows XP Service Pack 3 but it is failing to load file advapi32.dll, and the Spyware Doctor is constantly blocking a threat.

I am unsure of whether or not to cancel the installation as a warning is telling me that windows may not work correctly if I do.

The laptop is running extremely slowly. I have removed a number of programs to try to speed things up, and have managed to run a clean, defrag and disc space consolidation using PC tools Disk suite, which has improved things.

I am also getting a warning coming up at start up telling me that various files are "bad images".

Your help and advice will be appreciated

Hi can you try getting the scanlogs from these 2 applications
Run MBAM

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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. Alternatively, you can update through MBAM's interface from a clean computer,
    copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or
    CD and then copy it to the infected machine.
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. MBAM may "make changes to your registry" as part
of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM.
Please temporarily disable such programs or permit them to allow the changes.


Now run SDFPlease print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

For the sake of clarity, the message I am receiving is:

NOTEPAD.EXE - Bad Image
The application or DLL globalroot\systemroot\system32\UACakyfuxhl.dll is not a valid windows image. Please check this against your installation diskette

This is a sample... it is appearing for all files that I am trying to open.

The HJT logs are:

Hi,

I have managed to download MBAM to my desktop, but cannot run it. It did not auto start (even though I followed your instruction and made sure that the update and launch boxes were ticked), and every time that I try to run it from the shortcut on the desktop I am getting the "Bad Image" message followed by a notification that Spyware Doctor has blocked a threat. Is there any way that I can get around this?

Regards

Alan

Let's see if we can run GMER
Please download gmer.zip and save to your desktop.
  • Extract (unzip) the file to its own folder such as C:\Gmer. (Click here for information on how to do this if not sure.)
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security program drivers will not conflict with gmer's driver.
  • Click on this link to see a list of programs that should be disabled.
  • Double-click on gmer.exe to start the program.
  • Allow the gmer.sys driver to load if asked.
  • You may be prompted to scan immediately if GMER detects rootkit activity.
  • If you are prompted to scan your system click "Yes" to begin the scan.
  • If not prompted, click the "Rootkit/Malware" tab.
  • On the right-side, all items to be scanned should be checked by default except for "Show All". Leave that box unchecked.
  • Select all drives that are connected to your system to be scanned.
  • Click the Scan button to begin. (Please be patient as it can take some time to complete)
  • When the scan is finished, click Save to save the scan results to your Desktop.
  • Save the file as gmer.log and copy/paste the contents in your next reply.
  • Exit GMER and re-enable all active protection when done.

Same result again I'm afraid. I switched off all of the relevant real time protection and the file would not run from my C drive. I switched the protection back on and tried to runit again, but was again presented with the "Bad Image" message closely followedby a message stating that Spyware Doctor had blocked a threat.

I have also tried to copy the file to an external drive to run it from there, but I require a password to do this, which I cannot find.

Can you run MBam now? We need to update your Java JRE and then run DrWeb.

Your Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older version Java components and update:
  • Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  • Look for "Java Runtime Environment (JRE)" JRE 6 Update 13.
  • Click the Download button to the right.
  • Select your Platform: "Windows".
  • Select your Language: "Multi-language".
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • Click Continue and the page will refresh.
  • Under Required Files, check the box for Windows Offline Installation, click the link below it and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
Go to Start > Settings > Control Panel, double-click on Add/Remove Programs and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button and follow the onscreen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java versions.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-6u13-windows-i586-p.exe to install the newest version.
-- If using Windows Vista and the installer refuses to launch due to insufficient user permissions, then Run As Administrator.
-- If you choose to update via the Java applet in Control Panel, uncheck the option to install the Toolbar unless you want it.
-- The uninstaller incorporated in this release removes previous Updates 10 and above, but does not remove older versions, so they still need to be removed manually.


Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. To disable the JQS service if you don't want to use it, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click Ok and reboot your computer.



Dr Web
Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan 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".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Hi, looks like this rootkit is embeded and requires one of two actions now.. This PC has been compromised. A full wipe and reinstall or using the tools in the HJT section..
Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.


To continue with cleaning we need to run HJT/DDS.
Please follow this guide. go and do steps 6 and 7 ,, Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

As requested, I have posted the logs from HJT in a seperate post.

I could not run dds from my desktop as I kept getting bad image messages for the following .exe files:
EDS
FI
sort
cmd
findstr
WREGS
update
dds[1].scr

Therefore I ran it straight from the download screen.

I am quite happy to try to continue with the remval, but if a wipe and restore becomes absolutely necessary, then so be it. However, I do not have the original XP disks supplied with the laptop.

Thanks again for all of your assistance
