Adwcleaner Keeps Finding Chromium (and derivatives) PUP.Optional.Legacy

Recommended Posts

So little background: For a few months now I noticed a slight redirect in Chrome when I ran a search on the google home page. I have the uBlock Origin  extension running. Basically I would search and click a link (again random) and uBlock would stop the link. The link I had clicked was a redirect directly off of the google search page and not what google was showing. Just a fake example but say I searched for nugget ice maker and one of the results was nuggets.com and google would show that, BUT when I clicked the link, it gave me a redirect that would still lead to nuggets.com. uBlock would catch that and stop it. I would then go back and reclick the link and BOOM the link would correctly go straight to nuggets.com. Whatever was causing this was genious. Subtle link changed randomly that I am sure they are getting ad revenue from that most people wouldn't even see. 

I ran malwarebytes multiple times as soon I noticed and nothing ever came up and I thought I was losing my mind. Eventually I ran adaware as it kept happening. So adware finally came back with something but can't fix it:

Last night I uinstalled Chrome thinking it was an extension. I read Chrome could be bringing back some bad files from the cloud but not sure if that is the cause of "[ Chromium (and derivatives) ]"

Below is what adwcleaner is showing me:

***** [ Chromium (and derivatives) ] *****

PUP.Optional.Legacy             libedajeiljdoodmokbppgapcfbignci

I then ran RogueKiller and it seems to have found something and whether its related or not I am not sure. It found and quarantined this below:

Rebooted and ran RogueKiller and it found nothing. 

Re-ran  adwcleaner again and it's still finding the "PUP.Optional.Legacy             libedajeiljdoodmokbppgapcfbignci"

I followed the Malwarebytes thread and installed Farbar Recovery Scan Tool and below are my files.

Hello  and  :welcome:    @Cloves


My screen name is AdvancedSetup and I will assist you with your system issues.

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow all steps in the provided order and post back all requested logs
  • Please attach all log files to your post, unless otherwise requested
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans have been completed.
  • Temporarily disable Microsoft SmartScreen to download the software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting, and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Do not run online games while the case is ongoing. Do not do any free-wheeling or risky web-surfing.
  • Only run the tools I guide you to use. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked, Hacked, or Pirated programs are not only illegal but also can make a computer a malware victim.
  • Having such programs installed is the easiest way to get infected. It is the leading cause of ransomware encryption. It is at times also a big source of current Trojan infections.
  • If there are any on the system you should uninstall them before we proceed.
  • Please be patient and stick with me until I give you the "all clear". We don't want to waste your time, please don't waste ours.
  • If your system is running Discord, please be sure to Exit it while this case is ongoing.


Please post back the requested log and we'll be happy to assist you.

Do you need to run this Brother Printer monitor from 2012 ?  @Cloves

HKLM-x32\...\Run: [BrStsMon00] => C:\Program Files (x86)\Browny02\Brother\BrStMonW.exe [3076096 2012-06-06] (Brother Industries, Ltd.) [File not signed]
S3 BrYNSvc; C:\Program Files (x86)\Browny02\BrYNSvc.exe [266240 2012-06-05] (Brother Industries, Ltd.) [File not signed]



Please run the following fix


NOTE: Please read all of the information below before running this fix.

  • NOTICE: This script was written specifically for this user, for use on this particular machine.
  • Running this on another machine may cause damage to your operating system that cannot be undone.

Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program:   Farbar Recovery Scan Tool Download FRST64.exe

Save the attached file:  FIXLIST.TXT to this folder C:\Users\Danny\Downloads\00 - UTILITIES\00 - Malaware\

NOTE. It's important that both files, Farbar Recovery Scan Tool Download FRST64.exe, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.



Run the Farbar program with Admin rights and press the Fix button just once and wait.

The fix may possibly take up to 60 minutes to complete

If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log named Fixlog.txt in the same folder you ran the Farbar program from. Please attach that log on your next reply.


  1. NOTE:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity.
  2. NOTE: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications may be automatically closed.
                Also, make sure you know the passwords for all websites as cookies may possibly be removed in some cases, but not all cases.
  3. NOTE: As part of this fix, it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

The following directories are emptied:

  • Windows Temp

  • Recently opened files cache
  • Discord cache

I still use the brother printer and it's connected via wifi. Because it is an older driver and unsigned it could be a security hazard? 

No, probably not a security risk in general. Just wanted to make sure you're aware it was there. Often times customers don't realize they have something so old on their system.

Overall the log looks good and cleared up the items asked to clean up.

Please run the following scan @Cloves

Microsoft Safety Scanner

Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.   
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well


Please set File Explorer to SHOW ALL folders, all files, including hidden ones.  Use OPTION ONE or TWO of this article



I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of the computer.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted software from a system. 

The download links & the how-to-run-the tool are at this link at Microsoft 



Look on the Scan Options & select the FULL scan.

Then start the scan. Have lots of patience. It may take several hours.

  • Once you see it has started, take a long long break;  walk away.  Do not pay credence if you see some intermediate early flash messages on the screen display.  The only things that count are the End result at the end of the run.
  • The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

This is likely to run for many hours as previously mentioned  ( depending on the number of files on your machine & the speed of the hardware.)

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.


It is normal for the Microsoft Safety Scanner to show detections during the scan process.

It is scanning for basically all bread crumbs or traces of files and registry entries that "might" be or have been part of some infection or previous infection.

That DOES NOT mean the computer is infected. Once the scan has been completed it uploads the log to their Cloud service which then uses Artificial Intelligence to determine if in fact any of the traces are an infection or not.

Then it writes into the log on your computer what it found.


Thank you

BTW I am just doing some more digging on the "libedajeiljdoodmokbppgapcfbignci" I found that apparently it was pointing to a chrome extension for downloading soundcloud files (which is no longer available on the chrome store)

Links mentioning:

If the link is still there in Google Chrome go ahead and remove it

Ok going to run the Microsoft Safety Scanner and then report back. Sorry I guess I posted while you were posting. Then I will follow the google chrome post you mentioned. I ran the Microsoft Safety Scanner actually yesterday all night and it said it cleaned two things but there is no log. I will re-run now. 

The extension I mentioned isn't installed on my Chrome at least not now.

Thank you @Cloves

Please run the following as well


SecurityCheck by glax24              

I would like you to run a tool named SecurityCheck to inquire about the current security update status of some applications.

  • Download SecurityCheck by glax24: https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • If Microsoft SmartScreen blocks the download, click through to save the file
  • This tool is safe.   Smartscreen is overly sensitive.
  • If SmartScreen blocks the file from running click on More info and Run anyway
  • Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"  and reply YES to allow to run & go forward
  • Wait for the scan to finish. It will open a text file named SecurityCheck.txt Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt






Thank you

Thank you for the log @Cloves

Please uninstall, update, or otherwise address the following as appropriate for your system.



Then restart the computer and check for Windows Updates and install any found.


Then when done, let me know of any issues and how the computer is running now and if there are still any signs of an infection or not. As I said, I think the AdwCleaner is a False Positive as the folder is not there when we look to remove it.


Thank you
