Windows Modules Installer service will not start

Recommended Posts

While trying to find a solution to an issue on laptop with Windows 7 Home Premium SP1.


Part of the troubleshooting and solution required me to confirm if Windows Modules Installer (WMI) had Startup set to Automatic.


I did that, and then thought I should try to start the service but I was met with an unexpected response.


Windows could not start the Windows Modules Installer service on Local Computer.
Error 225: Operation did not complete successfully because the file contains a virus.


(See attached Graphic for exact windows prompt)


The properties dialogue for the executable is C:\Windows\servicing\TrustedInstaller.exe


So, I ran a Scan Using Emsisoft Internet Security V. and it came back clean.


Any assistance would be appreciated.


Edit: I later did a scan with MalwareBytes Rootkit Revealer and nothing was revealed.

If those don't resolve or clarify the problem, you can follow the steps here and post your logs in the appropriate forum.
