NTVDM and 16 Bit apps not running after install of MWB


Recommended Posts

Hello, it seems that MWB has changed the settings for NTVDM on my windows 7 machine. Can someone confirm how to reset whatever MWB has done to this machine to harden it?  I uninstalled MWB in an attempt to hopefully reset the configuration but no luck.  Thanks.

Hi,

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

Spoiler
  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program
    • You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

I am running Windows 7 Ultimate/32 and I have no problem running DOS programs like Quicken v8.0 under Windows NTVDM with MBAM v4.3 in full protection mode.

MBAM specifically targets Windows PE files and does not target legacy DOS and Windows applications.  I have no knowledge of MBAM modifying the NTVDM, the Win32 Virtual DOS emulator, in Win32 based OS' and which is not provided in any Windows Win64 based OS'.

When I tried to reply to the email, I get an error message stating that the "Hop count" has been exceeded.

Attached is the report you requested. Thanks for looking into this.  Bottom line is that VBS files are crashing and it could be due to NTVDM being restricted or another reason..but it started after MWB was installed. Thanks!

I was on bleeping computer and ran the FRST tool per their request. That was the file fix file they came back with. It made no difference. I still cannot run VBS files. The MWB diagnostic run was run after the fix file was run and tested so your diag data is clean. Thanks.
