My sons computer Malware infection of some type. It seems similar to an anitvirus2009 one that I had on mine earlier in the year. It will randomly start playing music or commercials. The resore points have been wiped out. I could not install and run MalwareBytes, so I renamed it before I downloaded it, then i renamed the exe file so that I could run it.

It found some trojans , rogue agents, and rootkit stuff. I removed them, but 2 days later (today), it started again . I updated the definitions and ran it, and it foud all the same stuff (7 items). I removed them, rebooted because it said one was in memory (as before), then ran it again, but there were still items there.

I now have tried Roguefix and SmitFraudFix. Both have said they found and removed stuff, but when I run Malwarebytes afterwards, the trojans , rogues, and rootkit stuff is still there.


Help !!! I don't know exactly what is in there, and I don't know what to do. Thanks in advance.

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.

I have already created logs, but was waiting on a response before posting them. Should I have posted them over there, or should I repost over there with the logs, or just sit here and wait?

We need to see your MBAM log

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

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.

That can be a quite nasty and dangerous rootkit.

One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

What is it that I have? I do no banking or anything else like that on this computer. It is for my son and wife to access the internet and email. It is less than 2 months old. I bought it with XP professional pre-installed and do not have a disc for it, but have an XP home disc for my other computer that has only been installed on that computer only.

Go ahead and post your DDS and rootrepeal logs in the HJT forum, they can help you clean up that infection.

It would be best to not use the computer in the meantime.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/253228/rootkit-and-backdoor-trojan/ 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 ask for help elsewhere. Doing so can result in system changes which may not show in 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 EXTREMELY 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. 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.

Please be patient. It may take several days, perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses.

To avoid confusion, I am closing this topic. Good luck with your log.
