Using Windows XP with Service Pack 2 and FireFox for browsing.

I am unable to access Internet however my Skype, Messenger and other online connections DO work.

Background: My AVG full version antivirus expired and I let it go months without protection (Yes I know... dumb move). Everything has been fine until yesterday. Yesterday some Antivirus that I never heard of (probably a rogue program) called Antivirus System Pro started complaining about a lot of viruses. That's when I installed the AVG Free Edition and started zapping all kinds of viruses (mostly Trojan Horse crap). The Antivirus Pro program still keeps popping up. Is it a legitimate program or some kind of Malware trying to make me spend money on their program to fix viruses they created? I never installed it.

By the way... my AVG installation is not allowing me to update to the latest file. It is complaining that Control File is missing on the Update Manager, yet when I reinstall AVG I get the same thing.

Now I have no browsing capabilities, but as I mentioned above I do have limited connectivity to the Internet, just no browsing.

I also noticed that my Windows Firewall was not running, so I turned that on today.

Thanks in advance for your help.

Hello lorenzo_CA,

Welcome to Bleeping Computer.

Sorry for delayed response. Forums have been really busy.

My name is fireman4it and I will be helping you with your Malware problem.
As I am still in training I will be helping you under supervision of our expert teachers, so there may be a delay between posts.

Please make no further changes or run any other tools unless instructed to. This may hinder the cleaning of your machine.

I will be analyzing your log. I will get back to you with instructions after it is approved.

Hello lorenzo_CA,

Please follow all instructions in order given. If you don't understand a instruction or can't complete an instruction, please Stop there and post your problem so we can find a solution.

1.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.

2.
Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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 using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

3.
Install Recovery Console and Run ComboFix

Download Combofix from any of the links below, and save it to your desktop.

Link 1
Link 2
Link 3

  • Close any open windows, including this one.
  • Double click on ComboFix.exe & 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.
  • If you did not have it installed, you will see the prompt below. Choose YES.
  • Posted Image
  • 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, ComboFix will continue it's malware removal procedures.

Note:The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you
should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.
  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

    Posted Image
  • Click on Yes, to continue scanning for malware.
  • When finished, it will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).
Leave your computer alone while ComboFix is running.
ComboFix will restart your computer if malware is found; allow it to do so.


Note: Please Do NOT mouseclick combofix's window while its running because it may cause it to stall.

4.
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.

OK, all utilities have been run and I have attached the log files to this reply.

The machine seems to be running fine now. I understand what you are saying about it might be a better idea to start from scratch, but this machine is mostly for my kids to access email and games and watch videos on you tube. I don't plan to do any sensitive work on it for now (such as online banking).

Question... is the any way to tell if it is still infected? Can I re-run some utilities to see if it still looks infected?

Thanks very much for your help. I look forward to hearing back from you on the analysis of these log files.

Lorenzo

You know I never saw it run any of the utilities against my second drive, which is used only for storing photos and videos.

Can I rerun all of these utilities against that drive? MBAM never asked me to run it against all drives now that I think about it. Let me know your thoughts on that extra disk. It is an internal storage drive (F:) on this workstation.

Thanks.

Lorenzo

Hello lorenzo_CA,

Great job running them tools and getting those logs back to me. :thumbup2:

Question... is the any way to tell if it is still infected?

Yes there is. Are you still having "Antivirus System Pro " telling you about infections?Has overall performance gotten better?

Can I re-run some utilities to see if it still looks infected?

Yes you can rerun MBAM any time just update it regularly and use it. However I suggest not running Combofix without supervision as it is a very powerful tool and miss use could result in a unfixable machine. Gmer is just a scanner and doesn't fix anything

Can I rerun all of these utilities against that drive? MBAM never asked me to run it against all drives now that I think about it. Let me know your thoughts on that extra disk. It is an internal storage drive (F:) on this workstation.

Yes you can use MBAM by doing a full scan and make sure (F:) Drive is checked

Hello Fireman4It,

Hope you had a nice 4th of July.

OK, I have updated my Java Runtime and I also ran the following utilities in the order listed:

Kaspersky Webscanner
MBAM
DDS

Kaspersky found a couple of viruses but I didn't see a way to remove them.

MBAM found a few viruses and I clicked to have them removed.

Then I ran DDS.

All logs are attached. Please advise next move.

Thanks,
Lorenzo_CA

Hello lorenzo_CA,

I see "no action taken" in your MBAM log. This is caused by not fixing or letting the computer restart to fix those files.

1.
Please update and run MBAM again this time hitting fix checked when the scan is complete.

2.
I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.

    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.
  • Push Posted Image

Will do.

BTW, I did have MBAM fix the errors but I think the log was created before the errors were fixed. Either way, I will re-run MBAM again as well as the other scanner.

Thanks for all your help.

All files have been attached.

I ran MBAM and have attached the DDS.txt and Attach.txt log files.

I ran ESET and it found and corrected two infected files. ESET log attached.

Computer is running very well. No signs f infection.

What worries me however is that we keep finding and correcting infections. MBAM didn't find any this time, but ESET did. Are these viruses the same ones that are just being not being fully removed or does my system keep getting reinfected with new viruses?

Thank again.

Lorenzo_CA
