my pc has been infected by some olmarik.mf trojan and my eset nod32 says its in the operative memory and can't eliminate it. i also downloaded spyware doctor, but when i tried to install it, the window would just close, and when it did open, it wouldnt show the installer.
so i tried being clever and changed the name of the folder so it wouldnt say "spyware", and kapoof! the installer magically appeared! but when i tried to install it, it just said "corrupt files, cannot install" or something of the sort.
This trojan keeps bringing in other trojans, which my nod32 picks up and eliminates.
i have downloaded and created DDS and Hijackthis logs. i have no idea what they mean. should i post them?
Here's my nod32 register:
\\?\globalroot\systemroot\system32\gasfkygvpxmpfu.dll Win32/Olmarik.MF Trojan

please help me, i'm scared.

Hi and welcome to BleepingComputer :thumbsup:

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Thanks for the response. I did what you said. downloaded MBAM and went through the process. I then had to reboot for MBAM to be able to eliminate some other viruses. I then did a second scan and it found more viruses! here are both logs.

You have a rootkit: Rootkit.TDSS

This is a common rootkit and can be cleaned in the HJT forum. Please follow this guide from step (6). Post a DDS log to the HJT/Malware forum and a Team member will be along to help you as soon as possible. You may wish to post a link back to this topic to see what was discussed thus far.

If you need any help with the guide, please let me know.
