IGDUMP folder in AppData\LocalLow - Can it, or its contents be deleted


Recommended Posts

The IGDUMP folder in AppData\LocalLow contains a lot of folders with each having two files in them.  One of the files has the .ext extension and the other one is a dll with the name sample.dll (looking at its properties, it is a file signed by Malwarebytes - both sha1 and sha256).

There are 271 such subfolders in IGDUMP containing a total of 508 files using up about 170MB (177,999,872 bytes). 

Can the IGDUMP folder, or its contents be deleted ?

Hi,

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

Spoiler
  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program
    • You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

Yes you can delete the contents. They should not build up like that though. I have one currently. We can look deeper for an issue if you like.

Why/When are these sub-folders getting created?  

All I can say it is part of the scanning process.

We can look deeper,

Can you please collect and upload as an attachment the diagnostic data using our MBST?

  • Download and run the Malwarebytes Support Tool
  • Accept the EULA and click Advanced tab on the left (not Start Repair)
  • Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

It is possible that Bitdefender is keeping MB from deleting those files.

Lets do a proper clean install of MB.

Please do the following Uninstall and reinstall using the Malwarebytes Support Tool

Please have lots of patience with the tool.  The first phase is a cleanup and does require a Windows Restart.
After the Restart, it may take 2 - 3 - 4 minutes till the Support tool screen shows up.   Please be patient and have faith.  Wait for it, whatever it takes.
The 2nd phase is where it offers to do a new Install.

After that is done,

I would  also create exclusions between Malwarebytes and Your AV to help prevent any possible conflicts or performance issues.  Please add the items listed in this support article to Your AV 's allow list(s)/trust list(s)/exclusion list(s) particularly for any of its real-time protection components and likewise add Your AV 's program folder(s) (likely located under C:\Program Files and/or C:\Program Files (x86)) to Malwarebytes' Allow List using the method described under the Allow a file or folder section of this support article and do the same for its primary data folder which is likely located under C:\ProgramData (you may need to show hidden files and folders to see it).

Finally, I suggest you uninstall and stop using any registry cleaners on your system. The can cause more issues than they can fix.

I added the items listed in this support article to the Bitdefender AV exception list and then uninstalled and re-installed Malwarebytes using the   Malwarebytes Support Tool.  After that I ran scan and noticed that the IGDUMP folder was created in AppData\LocalLow  but got deleted after the scan terminated.  

I'll check tomorrow after the daily scan and see if the issue has been resolved.   BTW, I also uninstalled the registry cleaner. 

It looks like your suggestion worked. 

Thanks for your help.

Be sure to add the BitDefender folders to the Malwarebytes allow list as well.

The goal is to exclude each one from the other one.🙂

Get rid of all of them.

jv16 PowerTools (HKLM-x32\...\jv16 PowerTools) (Version: 5.0 - Macecraft Software)

I would also uninstall HiJackThis as it is really not used anymore.

I suggest you also uninstall CCleaner because of the data collection policy's they have now since they were purchased by Avast. If you "must" keep it, never use the registry cleaner part of it.

I would also uninstall Bonjour. It is not really needed on a Windows PC.

What exactly is mDNSResponder.exe? (Bonjour)

https://www.groovypost.com/howto/howto/what-is-mdnsresponder-exe-and-why-is-it-running/

MDNSResponder, also known as Bonjour, is Apple’s native zero-configuration networking process for Mac that was ported over to Windows and associated with MDNSNSP.DLL.  On a Mac or iOS device, this program is used for networking nearly everything.  On Windows, this process is only necessary for sharing libraries via iTunes and other Mac applications like the Apple TV that were ported to Windows.  Bonjour allows different computers running iTunes to communicate with each other regardless of network configuration, this is because it enables automatic network discovery.

What Is mDNSResponder.exe / Bonjour and How Can I Uninstall or Remove It?
https://www.howtogeek.com/howto/6456/what-is-mdnsresponder.exe-bonjour-and-how-can-i-uninstall-or-remove-it/

I also highly recommend running on a regular basis,  Patch My PC . It is good at keeping most non MS 3rd party software up to date.

I removed the registry cleaners you pointed out, and the Bonjour app (I had left it there because I was not sure whether removing it would have any adverse effect on Windows).   I do not have HiJackThis - I had installed/used it one many years ago and then uninstalled it but I guess it left traces in the Registry?  

I was not aware that AVAST purchased CCleaner.   Have not removed CCleaner yet - I have not been using it to clean the registry, I have only been using it to clean the crap other applications leave.   I wonder if there is another decent app to cleanup the remnants as they tend to build.

It is quite a different world when it comes to software written for PC's vs software written for Mainframes.   I am a retired mainframe system software designer/developer - we took extreme care when we would update the Operating System libraries so it is difficult for me to accept that software developers would not cleanup the Registry and other Windows system directories/folders when removing their products - oh well ...

BTW, thanks for the tip regarding the app Patch My PC.  I was using the portable version of UCheck to determine which apps needed updates and then manually downloaded and updated them.  Patch My PC is definitely more convenient.  The only issue I had with it is during the updating it turned the desktop screen to black, and it remained so until I hit Ctrl-Alt-Del and got into Windows Task Manager and signed off my session.   I wonder if there is an option that I had to tweak and I missed it.

That can happen when explorer needs to restart after an update. Seen it several times myself. (use it on every computer I touch).😉

When I uninstall, I use a little utility called Geek uninstaller. It gets just the leftovers just from the program you are uninstalling and not a full reg clean.
