Virus posing as "Windows Antivirus" infected my machine - got through ESET Security

Hello -

Yesterday afternoon, my windows anti-virus software, ESET Smart Security, claimed to block an attack. Shortly thereafter, an icon appeared at the bottom of my desktop (where the icon for ESET, volume control, etc are located) - a pop-up warning window saying that Windows had been infected by a virus emanates from this icon. Then, a window pops-up posing as a Windows anti-virus program asking if I wish to run a scan and remove the infected files. If ignored, another of these same windows pops up within seconds, and continues to do so, filling the screen with such windows and rendering the computer unusable.

This seems reminiscent of a virus I encountered many months ago related to "Windows Anti-virus Pro" - similar symptoms. There are still grammatical errors in the warning window that comes up, albeit fewer this time around.

I was able to run a computer scan using ESET, and it found 3 infected files that it claimed to clean. But, this did not fix the problem. Moreover, this virus renders me incapable of opening other windows via icons on the desktop - it quickly closes the window of whatever I try to open within less than a second.

Please help - whatever assistance you can provide would be GREATLY appreciated.

Thanks,
CzarKib

Hello, my apologies for the delay.

Please follow the steps below. If you encounter any problems, please let me know.

MALWAREBYTES ANTIMALWARE
-------------------------------------------
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 Full 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.

regards, Elise

I've been following this topic as well and downloaded the Malware Software as instructed above.

It will let me install the program, however will not let me launch it. When I try to launch it....I get the "Security Warning: Application cannot be executed. The file wuauclt.exe is infected. do you want to activate your antivirus software now?" Is anyone else coming across this problem where the virus seems to block you from launching any Antivirus software? Thanks. :thumbsup:

AntivirusVirus,

You may want to start a new thread so these don't get mixed up.

As you are doing that, you will probably want to download rkill by Grinler and double click on it before trying to run MalwareBytes.

You will see a black box pop up on your screen as rkill runs and it will close on its own. Once it has finished, try running Malwarebytes once again following Elise025's directions.

Hi. Thanks for the directions! I was able to complete all of the steps that you outlined and have pasted my log file below.

Interestingly, when I turned on the computer to complete this, I did not get the same pop-ups that I had before. So, I am not sure if this is indicative of the virus "hiding" somewhere else or what.

Thanks again and I look forward to hearing how I should proceed from here.

This is more likely due to the fact we were able to clean the infection that was causing these pop-ups :thumbsup:

TFC
--------
Download TFC by OldTimer to your desktop.
(TFC only cleans temp folders. It will not clean URL history, prefetch, or cookies).
Close any open windows.
  • Double click the TFC icon to run the program
  • TFC will close all open programs itself in order to run,
  • Click the Start button to begin the process.
  • Allow TFC to run uninterrupted.
  • The program should not take long to finish it's job.
Once its finished it should automatically reboot your machine, if it doesn't, manually reboot to ensure a complete clean

NOTE:
It's normal after running TFC cleaner that the PC will be slower to boot the first time.

TFC (Temp File Cleaner) will clear out all temp folders for all user accounts (temp, IE temp, java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.

Hello, thats looking good. How is everything running now? Do you have any problems left?

To make sure we are not missing anything, I want you to run a rootkit scan.

GMER
-------
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.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.

regards, Elise
