Tea Timer asked if I wanted to allow a registry change by mmds.exe and because it's a Microsoft application I said yes. Since doing so mmds.exe will show up at least three on four times a day. When it does appear it will almost immediately take 100% of the CPU time and never release even 1%. Since all of the CPU time is dedicated to that one request there is 0% left for the server and so it will hang. The only way to resolve the problem is to power the server off and then power it back on again. A shutdown is impossible and mmds.exe can not be deleted in the Task Manager since there is 0% CPU remaining. Is this caused by a virus and how do I resolve this problem? The problem is on a Compaq server which is running Window NT 4.0

Hello and welcome. I am moving this to Am I Infected from Windows NT/2000/2003.
This appears to be a new malware. I would like to get a second opinion and then also run MBm.


Lets' upload this file for a second opinion on what it actually is..

Please make sure that you can view all hidden files. Instructions on how to do this can be found here:

How to see hidden files in Windows

Please click this link-->Jotti

When the jotti page has finished loading, click the Browse button and navigate to the following file and click Submit.

suspect.file

Please post back the results of the scan in your next post.

If Jotti is busy, try the same at Virustotal: http://www.virustotal.com/




Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

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 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. 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.
