Windows 7 won't boot because of MBAMSwissArmy


Recommended Posts

Hello,

I have a problem some peoples seems to get. My computer don't want to boot windows 7 because of

File : Windows/system32/drivers/MBAMSwissArmy.sys

Status : 0xc0000098

Info : Windows failed to load because a critical system driver is missing or corrupt.

 

In this screen i can continue and select some options (safe mode, safe mode with netw, safe mode with command ....) No one works, everytime it fails to boot. 

I found some topics in this forum and i tried things (put a bootable windows on a USB drive, tried everything, nothing works. From the windows installation menu i could reach a command pan I tried to "sc delete MBAMSwissArmy" and that didn't work (it seems I tried to call this from X: drive, that i suppose was temporary?).

Something seems to help people everytime, it's using FRST. But i don't get how to get this on my unbootable computer.

Can you help me please?

 

If you need more informations about my computer don't hesitate to ask me, 

 

Thanks in advance

Hello Denkaa and welcome to Malwarebytes,

You will need access to another PC to download and save FRST to a USB Flashdrive (memory stick). The boot sick PC to recovery environment, run a scan and post log...

Please download Farbar Recovery Scan Tool from here:

http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

save it to a USB flash drive. Ensure to get the correct version for your system, 32 bit or 64 bit

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

Plug the flash drive into the infected PC.

If you are using Windows 8 or 10 consult How to use the Windows 8 or 10 System Recovery Environment Command Prompt Here: http://www.howtogeek.com/126016/three-ways-to-access-the-windows-8-boot-options-menu/ to enter System Recovery Command prompt.

If you are using Vista or Windows 7 enter System Recovery Options.

Plug the flashdrive into the infected PC.

Enter System Recovery Options I give two methods, use whichever is convenient for you.

To enter System Recovery Options from the Advanced Boot Options:
  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
  • Use the arrow keys to select the Repair your computer menu item.
  • Select Your Country as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account an click Next.


To enter System Recovery Options by using Windows installation disc:
  • Insert the installation disc.
  • Restart your computer.
  • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
  • Click Repair your computer.
  • Select Your Country as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.


On the System Recovery Options menu you may get the following options:
Startup Repair
System Restore
Windows Complete PC Restore
Windows Memory Diagnostic Tool
Command Prompt

 
  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" and find your flash drive letter and close the notepad.
  • In the command window type e:\frst64 or e:\frst depending on your version. Press Enter Note: Replace letter e with the drive letter of your flash drive.
  • The tool will start to run.
  • When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

Thank you,

Kevin...

Thanks for that log Denkaa, continue...

Save the attached file fixlist.txt to your flash drive, same place as FRST.
Now please enter System Recovery Options as you did to get the log.

Run FRST and press the Fix button just once and wait.
The tool will make a log on the flashdrive (Fixlog.txt) please post it to your reply.


Reboot your system, does windows now load normally..? if so you will have to make a clean install for Malwarebytes...

Totally Remove Malwarebytes from your system:

Download the latest version of MB-Clean by clicking this link: https://downloads.malwarebytes.com/file/mb_clean save to your Desktop, or a folder of your choice.
 
  • Close all open applications
  • Double-click and run mb-clean.exe
  • A prompt with an option to clean up the system will appear:



Yes - will proceed with backing up the license key (Malwarebytes 3.x only) and initiating the cleanup process. (Recommended)
No - will exit the utility

Once the cleanup process is completed, a prompt will appear:

Yes – will proceed and post reboot you will be prompted to continue with the downloading, installation and activation of latest version of Malwarebytes 3.x (Recommended)
No – will exit the utility and you will not be prompted (post reboot) to download, reinstall and re-activate (Not Recommended)

We recommend rebooting immediately. Additionally, stopping at this step is not recommended and will most likely not resolve your issue(s).

Upon reboot, a prompt will appear:

Yes - will download, install and activate the latest version of Malwarebytes 3.x (Recommended)
No - will exit the utility and the cleanup process is complete...

Thanks,

Kevin...
