RegASM.exe continually being blocked

[JimM169]

Hi

My son's installed some programs he shouldn't have on our PC today (he even switched off the virus protection to do so!!)  and now we're getting a popup every few seconds that MalwareBytes is blocking a RegASM.exe file

I'm no tech expert guessing that the PCs been infected with some sort a virus. I've tried running the Malwarebytes scan and same with AdwareBytes, quarantined the files it detected but it's still popping up.

Any ideas on what else I can try to fix the issue - other then put our son up for adoption:)

Thanks

Hello   @JimM169    

My name is Maurice.  Let me know what name you prefer to go by.  I will guide you.

I need a report set for review.   This is a report only.

Please download Malwarebytes MBST Support Tool

Once you start it click Advanced >>> then   Gather Logs

 

Upload an archive once it is done. Attach the mbst-grab-results.zip from the Desktop.

 

• Please attach  mbst-grab-results.zip    to your reply , like displayed here.
• To send  ( upload)   attachments please click the "ADD Files"  link . Then browse to where your file is located and select it and click the Open button.

 

 

The set of data from the report will provide much needed information.

Please always attach reports as we go along.

Hi Jim.
This machine looks like it has been running Windows for near two days straight.  I need you to do 2 prelimary actions.
Disable Fast Startup

https://www.tenforums.com/tutorials/4189-turn-off-fast-startup-windows-10-a.html

 

Then restart the computer

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

Hi

I disabled fast Startup and rebooted the PC and the popups have stopped!!

I've attached a revised log but fingers crossed it was as simple as that

Thanks

Jim

Hi.  After the first steps from above are done, here are the next things to be done.

Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center 

Click the Security Tab. Scroll down to 

"Windows Security Center"

 

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".

 

{ We want that to be set as Off   .... be sure that line's  radio-button selection is all the way to the Left.  thanks. }

This will not affect any real-time protection of the Malwarebytes trial   😃.

Close Malwarebytes.

[    2   ]

The previous scan with Malwarebytes for Windows had found and removed several elements of different malware.  What the block protection notices are about is an executable file that is in a temporary sub-folder.  This will be dealt with below.  Do understand that the Malwarebytes trial's real time protections are keeping the pc safe from harm.

>

We will use FRSTENGLISH.exe   to run a custom script.    The system will be rebooted after the script has run.

This custom script is for  JimM169  only / for this machine only.

 

This custom script has some specific things, plus some general aspect to help the system overall.

NOTE-1:  This script will  run a scan using System File Checker to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files.   It will run the Windows DISM tool to check the system. 

NOTE-2: 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 will be automatically closed. 

The following directories are emptied:

• Windows Temp
• Users Temp folders
• Edge, IE, FF, Chrome,  and Opera caches, HTML5 storages, Cookies and History
• Recently opened files cache
• Flash Player cache
• Java cache
• Steam HTML cache
• Explorer thumbnail and icon cache
• Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

• Please be sure to Close any open work files, documents,  any apps you started yourself  before starting this.

 

• If there are any CD / DVD / or USB-flash-thumb or USB-storage drives attached,  please disconnect any of those.
• Please save the (attached file named) FIXLIST.txt   to the   Downloads folder

Fixlist.txt

Then, Start the Windows Explorer and then, go  to the Downloads   folder.

RIGHT click on  FRSTENGLISH.exe    and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.
  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
IF Windows prompts you about running this, select YES to allow it to proceed.

• IF you get a block message from Windows about this tool......

               click line More info information on that screen
               and click button Run anyway on next screen.

• on the FRST window:

Click the Fix button just once, and wait.

 

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. 
If you receive a message that a reboot is required, please make sure you allow it to restart normally.
The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the FIXLOG.txt with your next reply later, at your next opportunity

corrected oversight as to Downloads folder

[JimM169]

Hi again

Think I followed the steps correctly and log attached

 

Thanks

 

 

 

 

Fixlog.txt

[Maurice Naggar]

Thank you.  Good run.  The temporary files in sub-folders have been cleaned out, including the one regasm.exe  as well.

The Windows System File Checker did make some corrections.

Next, I suggest a new scan for viruses & other malware.

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 

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

 

Look on Scan Options & select FULL scan.

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

• Oce 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 screen display.  The only things that count are the End result at the end of the run.

 

Let me know the result of this.    This is likely to run for many hours   ( depending on number of files on your machine & the speed of hardware.)

The log is named MSERT.log  

the log will be at  

Windows\debug\msert.log

Please attach that log with your reply.

Hi Maurice

Picking this up the following day here in the UK

Ran the scan this morning and results are attached

Thanks

[Maurice Naggar]

Hello. Thank you.

Do one new scan.

Start Malwarebytes for Windows.

1. Click Settings.
2. In the General tab,    click on "Check for Updates " button.   

3. Watch & follow all prompts. 

4. Then click the Security tab.  Scroll down and lets be sure the line in SCAN OPTIONs for 

"Scan for rootkits" is ON 👈   Click it to get it ON if it does not show a blue-color .

 

Next, click the small x on the Settings line to go to the main Malwarebytes Window.   Next click the blue button marked Scan.

 

When the scan phase is done, be real sure you Review and have all detected lines items check-marked on each line on the left. That too is very critical.

>>>>>>      👉      You can actually click the topmost left  check-box  on the very top line to get ALL lines  ticked   ( all selected).         <<<<     💢

 

Please double verify you have that TOP  check-box tick marked.   and that then, all lines have a tick-mark

 

Then click on Quarantine  button.

 

Then, locate the Scan run report;  export out a copy;  & then attach in with your  reply.

Hi

Malwarebytes scab completed but no threats found (presumably that's good?)

Thanks

 

 

 

Scan.txt

[Maurice Naggar]

Thank you.  Yes, that is good.

Let me suggest that you get your browsers each, as applicable, to have the Malwarebytes Browser Guard.

See Support article how-to

https://support.malwarebytes.com/hc/en-us/articles/360038520374-Install-Malwarebytes-Browser-Guard

The EDGE browser will work with & accept the Browser Guard for Chrome.

Note: If your pc has  Opera or Brave or Vivaldi browser, you can install the Chrome version of the Malwarebytes Browser Guard ( on each as appropriate).

[JimM169]

Hi

Thanks, already installed the Browser guard on chrome and thanks also for all your help with resolving this issue, fantastic service 

 

 

 

[Maurice Naggar]

You are very welcome.

Consider using PatchMyPC, keep all your software up-to-date - https://patchmypc.com/home-updater#download

To remove the FRST tool & its work files, do this. Go to your Downloads folder. Do a RIGHT-click on FRSTENGLISH.exe & select RENAME & then change it to

UNINSTALL.exe

 
Then run that ( double click on it) to begin the cleanup process.  

Delete MSERT.exe

Detete the mbst-grab-results.zip on the Desktop.

Delete mb-support-1.8.7.918.exe on the Downloads folder.

Any other download file I had you download, you may delete. 

Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.

Stay safe.  I wish you all the best.     
I am marking this case for closure.

All the best to you.  😃
