Windows 7: stdrt.exe running from windows temp??

stdrt.exe running from windows temp??

My firewall keeps triggering on stdrt.exe

from: Windows/Temp/mrt643E.tmp (or Similar, because it regenerates if deleted)

I can delete that directory and it will regenerate. I see other queries about this one on the web. It isn't tripping anyone's virus detectors, but anything that keep regenerating itself, running out of temp and trying to contact the internet seems suspicious. I want to know what it is.

That directory is also full of file ending in .mfx. Which points to multimedia fusion.

Anyone have this directory in Temp, anyone know what is causing it?

Apparently it's an MMF runtime. It appears when you test your applications via MMF.

But what the heck is MMF/Multimedia fusion? Is this part of windows?

It appears to be a framework for easy app building, so something I have installed was built with this app and it keeps putting an EXE in temp and calling home? Seems very shifty.

I was assuming that you build applications...

Apparently it's also malware, maybe? I'd run Malwarebytes' Anti-Malware

Malwarebytes

All in all, remove the following files:

C:\WINDOWS\SYSTEM\REGSRV.EXE
C:\WINDOWS\TEMP\MRT2.TMP\STDRT.EXE

Actually I found it.

Kind of Duh, moment, but for future reference to anyone else hitting it.

It was Gigabytes Easytune software. Even though I don't have it set to run on startup, it was still running it's background process.

The Duh moment. There was a UAC query at startup to let it modify the system, I was just blindly hitting yes for a while.

When I finally said no, there was no stdrt.

Edit: not 100% sure on that. I deleted a few things and removed the REGSRV.EXE

Anyway whatever it was, is cleared now.

I have this bloody thing on my system as well. I thought I had cleaned it last week but it's back. I even deleted it and replaced it with another exe and hid the file, and it came back. It's using almost 300MB of memory and since I spotted it on my system have noticed serious performance issues.

It's pissing me off. Gonna try a few a few more things...

I am usually quite good at cleaning malware, but this thing tested me.

Malwarebytes ended up letting me down... So I went looking else where. UnHackMe, the free version, is what ended up cleaning it.

I also used Combofix and HiJackThis! for good measure.

You might also want to use (and keep) TFC by Old Timer TFC - Temp File Cleaner by OldTimer - Geeks to Go Forums and save it to your desktop.
Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista/Windows 7 right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

TFC (Temp File Cleaner) will clear out all temp folders for all user accounts (temp, IE temp, java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder. It also cleans out the %systemroot%\temp folder and checks for .tmp files in the %systemdrive% root folder, %systemroot%, and the system32 folder (both 32bit and 64bit on 64bit OSs). It shows the amount removed for each location found (in bytes) and the total removed (in MB). Before running, it will stop Explorer and all other running apps. When finished, if a reboot is required the user must reboot to finish clearing any in-use temp files.

TFC only cleans temp folders. TFC will not clean URL history, prefetch, or cookies. Depending on how often someone cleans their temp folders, their system hardware, and how many accounts are present, it can take anywhere from a few seconds to a minute or more. TFC will completely clear all temp files where other temp file cleaners may fail. TFC requires a reboot immediately after running. Be sure to save any unsaved work before running TFC.

Great suggestion. I will do that myself also.
