Hello,

I'm Sam from the UK, hope all is well

I have recently (through use of ESET Nod32 anti-virus software) discovered I have an Olmarik Trojan on my computer and I can't get rid of it! It shows as system32/Olmarik Trojan on nod and says it is unable to do anything with it. I have searched for walkthroughs on how to tackle this but I am not comfortable with registry or dll files. I have followed instructions on this site for similar problems but I read it's best to get your individual case looked at.

For info I have used the malwarebytes software which doesn't pick up the Trojan.

Any help you could give me would be greatly appreciated. Keep up the good work.

Sam

Ok, thanks for your response

I downloaded the 2 programmes but when I attempt to start is safe mode it displays a load of "multi disk partition files" most of them end with system32 files (.sys) it then briefly goes to a blue screen with writing before shutting down.

where should I go from here?

Thanks muchly,

Sam

SUPERAntiSypware has a built in "Repairs" feature to fix policy restrictions and certain Windows settings which are sometimes targeted by malware infection. To use this feature, launch SUPERAntiSypware.
  • Click the Repairs tab.
  • Click on (highlight) "Repair broken SafeBoot key" and then click the Repair button.
  • You may be asked to reboot your computer for the changes to take effect.

Hello again,

I followed your instruction but I'm still having the same issue. Once I select safe mode it asks me to select an operating system, there is only one option so I select that and then I get the list of files, I think all the files are in the drivers subfolder.

Cheers,

Sam

Hello Sam, it appears that the files are corrupt. That leaves 2 choices.
We move to he HIJackThis (Malware Removal forum or we need to reformat this PC. What would you prefer?

I think I would chose the first option, simply because it's not reformatting!! What will this entail?

Thanks for your help thus far

Sam

Also,
I notice in your original reply you say if I can't access safe mode then to run the scans anyway but to let u know.
Should I go ahead and run the scans?

OK, yes we can do that,perhaps we'll still get it.
Run MBAM, ATF, SAS and ESET, post logs ...ATF has no log.
When all are done try entering Safe mode.

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

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

alternate download link

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 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.

Just to clarify am I running the 3 scanners, trying safe mode again and then running mbam again as per instructions? Or should I just be running mbam once?

Thanks again,

Sam

Hello Sam.. i removed my last post. After discussing this with other Malware staff it is important we NOT run ESET.
the ESET online scanner will delete the file (if the user choses so) with quite disastrous consequences (i.e. bsod on boot)....

As this is a TDL3 rootkit infection the ONLY safe method of removal is thru the HJT forum as mentioned earlier.



You will need to run HJT/DDS.
Please follow this guide. go and do steps 6 thru 8 ,, 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.

Hello again,

I will follow the instructions and let you know how it goes. When you say don't run eset do you mean nod32 as I already ran this and it told me I had the olmarik.

Thanks

Sam
