User Comments

DDMI2.sys is a trojan/spyware! It gets installed on your computer, along with at least 3 other files, by visiting a malicious website. It sets up a web server on your computer that phones home periodically with all of your personal data. Thus far, none of the antivirus or antispyware programs are able to eliminate it. I had to do it manually.
Part of Dell Support 3.1 (Was not contradicted by well known MVP) Should keep it to be able to update your drivers and such on a Dell box.

Best practices for resolving DDMI2 issues

A clean and tidy computer is the key requirement for avoiding problems with DDMI2. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the DDMI2.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
