The computer boots into it's installation and functions for the most part with programs that have been installed previously, however there are redirects happening in all three browsers installed (Firefox, Chrome and IE); an incredible delay in launching installed programs and all of my go to spyware eliminators can be downloaded; but the .exe files cannot open. An item appears in the Task Manager, but goes nowhere with no indication of failure or status.

The system is also running Service Pack 2. All attempts to update 3 (actually any Windows updates) hang at a midway point and don't indicate failure or status. Microsoft Security Essentials won't install until it is updated to Service Pack 3, and the only free antivirus that has installed was Sophos. It was not able to resolve any issues. Combofix was attempted, but even in Safe Mode it does not open. This appears to be quite an interesting infection, my next thoughts are to somehow acquire a Sony Vaio (I am uncertain how to determine exactly which model this machine is) recovery disk and try to save the OS that way. Are there any other suggestions on things that can be attempted? the only reason we are fighting to save this install is there are programs critical to the business of which the install CD is not available, and it is out of support by the manufacturer anyway.

Thanks,
Jesse

Hello and :welcome: to BleepingComputer.

Let's see what we're dealing with here.

Please try running Malwarebytes this way.

Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

Link 1
Link 2
Link 3
Link 4
  • Before we begin, you should disable any anti-malware software you have installed so it does not interfere with RKill running. This is because some anti-malware software mistakenly detects RKill as malicious. Please refer to this page if you are not sure how to disable your security software.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply
***************************************************

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link

IMPORTANT!!! - when you save the file, rename it to something random, such as bubbles.exe This must be done before beginning the download!

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. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition updates, manually download them from http://data.mbamupdates.com/tools/mbam-rules.exe'>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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Hello and thank you for your response. I ran Rkill above and the black window did appear and disappear, I then re-downloaded Malwarebytes from the link above and renamed the file to bubblesmbam1.exe and ran it.

I did have a previous installation of Malwarebytes installed when I ran the new file, so I don't know if that could have affected the results. However the result was that Malwarebytes installed in the manner that I would expect it to, it then rewuested that I reboot the computer, which I did. When it came back up the tray had the red M in it and stated that the database was out of date and that it would update itself. it is now at 7035, which appears to be from the middle of July, so I don't know if that is the most current version. I cannot open the program, nothing even comes on the screen when I click any of the icons. There was no scan ran, so I assume that there is no Malwarebytes log to speak of.

I have also ordered the Sony VAIO reinstallation CDs, however they only appear to be good for a complete wipe and reinstall. I have ran sfc /scannow and not been prompted for the CDs like I was previously, so I still don't know if it is a corrupted system file although I think not. I have also ran secedit again with no new results. Safe mode still does not function any differently then the full mode.

I am out of ideas. Does anyone else have any?

Thanks,
Jesse

Kaspersky executed and has ran in safe mode and deleted nine objects, I also was able to start it up in normal mode and it has detected 6 objects and an active rootkit: MEM:rootkit.Win32.TDSS.d and Kaspersky stops the scan at this point and recommends a reboot to fully disinfect the file. I have gone through three reboots so far, but the process seems to remain active.

Does anyone have any advice on this particular rootkit and how to remove it?

Thanks,
Jesse

Hello.

Let's try this.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.

TDSSkiller got it, all is well and I can now open Spybot, Malwarebytes and hopefully Combofix. I will then do the Windows Updates and install Security Essentials, in the mean time I have Kaspersky free trial watching over the system. I am really impressed with their detection algorithms, it got through where others couldn't.

And thanks for your help Blade, this computer's hard drive configuration shall be saved thanks to you. :)

Jesse

I'm glad to be able to help.

ComboFix (CF for short) is intended by its creator to be "used under the guidance and supervision of an expert", NOT for personal, unsupervised use. Please read Combofix's Disclaimer. When CF is run without trained assistance, it can no longer be considered a "safe" tool. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.
