If you are using Windows 98 or Windows Me (Millennium Edition), then you will also need to remove the registry value that starts the Machine Debug Manager. To do this, follow the steps listed below.

Warning: The steps given below prompt you to make changes to the system registry. You should be comfortable in doing this, as incorrect changes made to Windows registry may seriously harm your PC.

Is Mdm.exe a virus?

Although the true Mdm.exe file is a safe file, many spyware and virus programs disguise themselves by adopting similar file names. Some such malware programs that disguise themselves as mdm.exe are listed below, along with the corresponding file location:

Malware File Location
W32.Sdbot.APE %SystemRoot%
W32.Unubot.B %SystemRoot%
W32.Bckdr-QJR %SystemRoot%
W32.Agobot.AQ %SystemRoot%System32mdm32.exe
W32.Rbot.AIJ %SystemRoot%System32mdm32.exe

Note: %SystemRoot% is a variable and points to the location where Windows is installed. By default, for Windows Vista, XP, 98/95/ME the location is C:Windows and for Windows NT the location is C:Winnt.

If your PC is infected with any malicious files, you should immediately scan your system using efficient AntiVirus and AntiSpyware tools. Furthermore, these malicious programs embed harmful entries or keys within the system registry, so we recommend you use a robust registry cleaning tool, such as RegServe to scan and weed out malicious entries from the registry.
