Hello!

After long searching I deleted the "Rootkit.boot.SST.b" via Kaspersky Rescue Disk.

Now I am able to run TDSSKiller and he finds 2 objects.

Now I can't find an answer if I can safly delete them?

These are the scan Results:

Now how can I be sure that all the junk from the rootkit is deleted since previsouly following programs found nothing:

Emsisoft Emergency Kit - Super antispyware - Malwarebytes - AVG - kaspersky Virus Removal Tool - Combofix didn't even start - Stinger | Spybot S&D | Hitman | AVG Virus Removal Tool


Kind regards,

Vincent

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can.

Please download and run Security Check from HERE, and save it to your Desktop.

* Double-click SecurityCheck.exe
* Follow the onscreen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt; please post the contents of that document.

Malwarebytes Anti-Malware

NOTEMalwarebytes is now offering a free trial of their program, if you want to accept it you will need to enter some billing information, so that at the end of the trial you would be charged the cost of the product. Please decline this offer, if you are unable to provide billing information. If you want to try it out, then provide the billing information.

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Full 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.


SUPERAntiSpyware:

Please download and scan with 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 it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • 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. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, 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 unchecked (leave all others checked):
    • Ignore files larger then 4mb
    • Ignore non-executable files

    Now Perform the 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.[list]
    • 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.

SAS Portable
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.


All scans above should be performed in regular boot mode, and if that is not possible then I will post instructions in a follow up reply on how to get into Safe Mode to perform the scans. Also all scans should be COMPLETE and not quick unless specifically instructed to do so.

But this doesn't answer the question what to do with the 2 files that kaspersky's TDSSkiller found. Can I quarantine or delete those 2 files safely?



[b]Any chance that a Mod can move this topic to a more apropiate section since I am now posting on request logs and this wasn't allowed in this section.

So what other tools have you ran?

DDS, Farbar Service Scan Log, Combofix, are logs that cannot be here.

I Ran the Kaspersky rescue CD wich deleted the rootkit.boot.sst.b. After that I ran the tdsskiller and he detects the 2 files above in the screenshot.

Before I ran kaspersky rescue CD Combofix wouldn't run & the other tools I mentioned in my first didn't detect anything.


But now can I deleted/quarantine the 2 files found by TDSSKiller or do I have to do something else?

Greetz!

Yes you do, and the rootkit detection could be a false positive.

I'm 99.9% sure malwarebytes & superantispyware is not going to find anything.

(Yes I'm scanning for you)

So the only question is left if those 2 doesn't find anything if I can remove the 2 things I found with tdsskiller with selecting additional options :

- Verify driver digital signatures
- Detect TDLFS file systems

The 2 things TDSSKiller with those options selected are the following:

Unsigned file
Service: Appdrv
Suspicious object, medium risk
Service type: Kernel driver (0x1)
Service start: Demand (0x3)
File: C:\Prograim Files\Dell\NICCONFIGSVC\APPdrv.sys
MD5:

Unsigned file
Service: omci
Suspicious object, medium risk
Service type: Kernel driver (0x1)
Service start: Demand (0x1)
File: C:\WINDOWS\system32\DRIVERS\omci.sys
MD5:

As shown in the screenshot in the first post but here posted again:

Reason is because I deleted the TDSS with Kaspersky Rescue Disk already

I have removed the Combofix log as those logs are not permitted in this section of the forum.
