First of all, I am new here and I am not good with computers.

I've just got infected (less than an hour ago) by a Trojan by the name of 'Lmok D'.

I am using the free version of avast! Antivirus and also SUPERAntiSpyware. Both were unable to detect the Trojan and therefore unable to remove/repair/quarantine it. In fact, it was Yahoo Anti-Spy that detected 'Lmok D' on my system but when I tried to remove it with Yahoo Anti-Spy, an error message popped up. It showed "Cannot quarantine. Administrative rights may be required to quarantine items".



Yahoo Anti-Spy gives the following details on the Trojan:
Name: Lmok D
Category: Trojan
Description: http://www.3.ca.com/securityadvisor/pest/p...px?id=453137527

Type: Key Location: hkey_classes_root\clsid\{39f7e362-828a-4b5a-bcaf-5b79bfdfea60}
Type: Key Location: hkey_local_machine \software\microsoft\windows\currentversion\explorer\browser helper objects\{39f7e362-828a-4b5a-bcaf-5b79bfdfea60}



And I am currently running on Windows Vista Home Premium.

Any help to fix this, please?

Thanks.

Hi raymiester,

Let's try Malwarebytes...

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. Reagardless 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.

Firstly, thank you for your help. I followed every step of what you told me to do. "The scan completed successfully. No malicious items were detected, click 'Main Menu'." I think it failed to detect the Trojan? Nevertheless, here's the log:

Followed your instructions, here's the log:


SUPERAntiSpyware Scan Log
http://www.superantispyware.com

Generated 08/23/2008 at 10:26 AM

Application Version : 4.15.1000

Core Rules Database Version : 3545
Trace Rules Database Version: 1534

Scan type : Complete Scan
Total Scan Time : 00:33:42

Memory items scanned : 202
Memory threats detected : 0
Registry items scanned : 6597
Registry threats detected : 0
File items scanned : 70384
File threats detected : 0



Once again, no threats were detected.

Subsequently I tried removing the Trojan using CA Yahoo! Anti-Spy in Safe Mode and the error message stating "Cannot quarantine. Administrative rights may be required to quarantine items" did not appear this time round. Hence, I've so called managed to remove the Trojan in Safe Mode.

Upon rebooting, I did another scan using CA Yahoo! Anti-Spy (this time in normal Windows mode) and the Trojan wasn't detected. Does this really mean I've managed to remove the Trojan? Please advise, thanks!

This infection will require further investigation and probably the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 9 there are instructions for downloading the HijackThis Installer and creating a log. This is an automatic setup version which will install the program in the proper location.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team.

A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic.
