BleepingComputer.com: Trojan-Downloader.WMA.GetCodec.n

I have Webroot, Spybot Search and Destroy, Trend Micro Anti-virus, and Online Armor. I still noticed some problems; like my windows media player turns into the blue screen of death when opened, delayed start-ups and such. I downloaded Ad-aware, and it came up with 9 redirected hostfile entries. Attempts to quarantine them through ad-aware have failed. I checked Online armor to find that my firewall had been turned off and a ridiculous list of 200 or more sites were being "Trusted". If it not were Spy Sweeper, I would probably be unable to run my pc from all the pop-ups. Spy Sweeper didn't tell me that they were there, but at least that shield is blocking them for now. Something is also messing with my uninstallers. I.e. I tried uninstalling Online Armor to reinstall and reset the settings, but no luck. The uninstaller window won't even come up. Firefox is being affected, too. When I am browsing, it will try to close everything. Windows Explorer is freezing more often. I downloaded GMEr and tried to run it three times, but it froze each time. I started my pc today (11-11) to find that I could not access the internet, even though it said networks were available. Someone has hacked my Online Armor. In order for me to access the internet, Online Armor wanted me to allow another computer to link with mine. I said block. Luckily I created a restore point a month ago and restored the system. I ran Kaspersky Scanner and found Trojan-Downloader.WMA.GetCodec.n and Trojan-Downloader.WMA.GetCodec.f.
Please help.

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

• 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. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Thanks so much for helping me. I already have MBAM and have been running it. I updated, ran it again, and still nothing. I think that may be affected too, because it keeps freezing when I try to view the logs. Should I try re-installing or should I try something else? I don't think I mentioned this in my first post, but my admin rights are being affected too. My anti-virus is trend-micro, but it can't update. I got avast to compensate.

Sorry, I forgot to mention that the MBAM report keeps coming back clean, but doesn't have the log window pop open at all. Also, when my pc freezes, I can't bring up the task manager. I have to force shut down my pc when this happens.

You have some infected Mp3 files
Can you run Kaspersky again and post the log please

Sorry for the delay in my reply, my access to wireless is limited. Anyways, Kaspersky keeps freezing and such. Luckily, about a month ago, I ran it and saved the report.

Since I found out the infection came from limewire, I uninstalled it and never plan on using it again.

Did you delete those two files? you should.
You always run the risk when using P2P and torrent sites, no matter how safe they claim to be

I deleted the folder, but the problems remain. I don't know where the files got moved to, but I think it is hiding as another process. Isn't there a program I can use to find it again?

I am so screwed. I can't even save any files. I says that I don't have permission, but I AM the admin. I have an earlier restore point- not before the infection, but before it got this bad. Should I restore? I am going to a friend's house later, so I will try to download these files to my usb and transfer them.

If you are using XP you can try SDfix

Please print out and follow these instructions: "How to use SDFix". <- for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"

• Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  
• Please be patient as the scan may take up to 20 minutes to complete.
  
• When the process is complete, the SDFix report log will open in Notepad and automatically be saved in the SDFix folder as Report.txt.
  
• If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  
• The SDFix report log (Report.txt) will open in Notepad and automatically be saved in the SDFix folder.
  
• Please copy and paste the contents of Report.txt in your next reply.
  
• Be sure to re-enable you anti-virus and and other security programs before connecting to the Internet.

I have Vista. Fortunately the usb method worked. I ran AVG with no problems. My browser windows connect and open faster now. This would be a good time to mention that I heard combofix was amazing at getting rid of stuff like this. I didn't run it for fear of ruining my pc beyond repair. Anyways, it found a remnant of it combofix and I don't know if it was a false positive.

Hello Azrea,

Now that you log is posted here: http://www.bleepingcomputer.com/forums/topic185611.html 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 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.

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. Good luck with your log.

The BC Staff
