Firefox malware

Recommended Posts

Last time I tried this somehow my post was shredded and it has been 48hours since, so I'm gonna try my luck again!

I have pretty much a similar problem than others here, I have google search directs, my hibernation doesn't work, and recently my svchost.exe process by user system is prone to go to 100% CPU and freeze my computer.

Hello ,

And :) My name is Elise and I'll be glad to help you with your computer problems.

I will be working on your malware issues, this may or may not solve other issues you may have with your machine.

Please note that whatever repairs we make, are for fixing your computer problems only and by no means should be used on another computer.

  • The cleaning process is not instant. Logs can take some time to research, so please be patient with me. I know that you need your computer working as quickly as possible, and I will work hard to help see that happen.
  • Please reply using the Add/Reply button in the lower right hand corner of your screen. Do not start a new topic.
  • The logs that you post should be pasted directly into the reply. Only attach them if requested or if they do not fit into the post.
  • Unfortunately, if I do not hear back from you within 5 days, I will be forced to close your topic. If you still need help after I have closed your topic, send me or a moderator a personal message with the address of the thread or feel free to create a new one.

You may want to keep the link to this topic in your favorites. Alternatively, you can click the button at the top bar of this topic and Track this Topic, where you can choose email notifications.




One or more of the identified infections is known to use a backdoor.

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

I would advice 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 infection 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. If you decide to go through with the cleanup, please proceed with the following steps.



Please download ComboFix from one of these locations:


  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, or if you are running Vista, ComboFix will continue it's malware removal procedures.


Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:


Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

Thank you! I tried to run combofix, but I had trouble disabling AntiVir. I opted for temporarily deleting it, but combofix is still detecting active real time Avira Antivir PersonalEdition classic. I also got an error message that it would only run for Windows32. Evidently I have 64.

Should I run it anyways?

I don't know. I am fairly computer illiterate. Where would I check that?

also, not sure if that matters, I reinstalled some drivers for my motherboard after my onboard soundcard had a hicup. I didn't think anything of it, but now that I checked it the file reads C-Media_XP64_XP_2K_ME_98(AC97Integrate003).

It is possible you inadvertently installed some 64 bit software. It would be best if you downloaded and installed the 32 bit version of the drivers.

Can you please try to rerun Combofix? The fact that you have the system32 folder, indicates this is a 32 bit OS. The GMER scan results confirm this. The infection you are having is not seen on 64 bit systems.

I tried to run combofix again. But when it tries to install the MS recovery console I get the error message "Can't enumerate bootpartition". It prompts if it should scan anyway, I said yes - and then it started to scan but took ages to finish. I couldn't kill the process either so I forcibly cut the power to my computer after an hour and rebooted.

Is there a way to instally the recovery suite in a different way?

I also reinstalled the 32W driver.

thank you so much for your help and patience!

So I tried to instally the MS recovery suite from my XP installation CD with the instructions from http://www.bleepingcomputer.com/tutorials/tutorial117.html but it didn't work. It didn't find the C /boot.ini or something like that.

I bought this computer and it had Linux preinstalled. I installed XP on it later - and when I boot my computer it says cant find boot.ini after which it boots C:windows. The exact lettering my be off but that's the gist.

Was that the complete log? It should have more in it. Can you please verify if this is a copy/paste error or if the log was this short indeed (which may indicate combofix didn't complete it).

I think the boot.ini problem is related to the fact you first installed Linux, then Windows. Do you still have a linux distro installed and if so, do you know what boot loader is used (Grub, Grub2)?

Hello Elise!

That is the complete log. I had run combofix in safemode as instructed; it rebooted into normal after it was finished and that was the only combofix.txt file that I found in the folder.

I had reformatted my harddrive before installing Windows, but the OS that was installed on it beforehand was Suse Linux 10.0. I still have the Suse Linux installation package, it as with the computer when I bought it. I don't know what Grub is though.

I ran combofix again. I didn't get any popups yet, but I haven't yet tried wether hibernation is working or not. You guys rule for helping out like this.

Hi, you were infected with the TDL3 rootkit. This rootkit infects a random file in your Drivers folder and so ensures it will be loaded on computer startup. Once loaded, this rootkit can control pretty much anything it wants on your computer. It was for example responsible for the fact that you couldn't post a complete log in your first post in this topic.

It is relatively easy to fix: the only thing that we needed to do, was to replace the infected file with a clean copy. We did this with Combofix.

I will give you some prevention advice after the following steps. :)



I'd like us to scan your machine with ESET OnlineScan

  1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  2. Click the esetOnline.png button.
  3. For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)

    1. Click on esetSmartInstall.png to download the ESET Smart Installer. Save it to your desktop.
    2. Double click on the esetSmartInstallDesktopIcon.png icon on your desktop.

    3. Check esetAcceptTerms.png
    4. Click the esetStart.png button.
    5. Accept any security warnings from your browser.
    6. Check esetScanArchives.png
    7. Push the Start button.
    8. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
    9. When the scan completes, push esetListThreats.png
    10. Push esetExport.png, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
      Note - when ESET doesn't find any threats, no report will be created.
    11. Push the esetBack.png button.
    12. Push esetFinish.png

That is looking great. :)



Your machine appears to be clean, please take the time to read below on how to secure the machine and take the necessary steps to keep it clean :)

Please do the following to remove the remaining programs from your PC:

  • Delete the tools used during the disinfection:
    • Click start > run and type combofix /uninstall, press enter. This will remove Combofix from your computer.
    • Delete DDS and GMER (this is a random named file).

Please read these advices, in order to prevent reinfecting your PC:

  1. Install and update the following programs regularly:
    • an outbound firewall
      A comprehensive tutorial and a list of possible firewalls can be found here.
    • an AntiVirus Software
      It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    • an Anti-Spyware program
      Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
      SUPERAntiSpyware is another good scanner with high detection and removal rates.
      Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    • Spyware Blaster
      A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.
    • MVPs hosts file
      A tutorial for MVPs hosts file can be found here. If you would like automatic updates you might want to take a look at HostMan host file manager. For more information on thehosts file, and what it can do for you,please consult the Tutorial on the Hosts file

[*]Keep Windows (and your other Microsoft software) up to date!

I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.

Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!

[*]Keep your other software up to date as well

Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.

[*]Stay up to date!

The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing.

Some more links you might find of interest:

Please reply to this topic if you have read the above information. If your computer is working fine, this topic will be closed afterwards.

Yep, I had done it as instructed. The folder and that file was the only thing left, I dunno why it didn't completely uninstall like the rest. In any case, I've manually deleted it.

Again, thank you for your patience and great help. I had been sort of desperate beceause everybody I asked just shrugged or said "get a computer tech to take a look". This forum is awesome and I will promote it to anyone I know.
