malware.sandbox.54 detections

[TerryMeh]

Hi, running version 4.5.23.  Last couple of days when downloading some zipped files from a well-known US financial institution, Malwarebytes will flag them with a "malware.sandbox.54" error.  It's consistent with this firm and as they're zipped files with personal information, I don't wish to upload them.  From the log of one of the files it will say

"File: 1 Malware.Sandbox.54, [file path/name], No Action By User, 54, 0, 1.0.66324, 54, dds, 02193304, 86052630A58CFE24A608E030BBCFA12C, 3723C2114BAA09F0D8A9414AC084C674A3BBF19D75114FD0EBDB3BB14E491049

 

Please advise on the significance of "malware.sandbox.54"

 

Thank  you

Hi Maurice,

I followed your instructions and updated Malwarebytes.  Also redid a scan.  No new items were found (the original quarantined items were still in quarantine).

Attached are the scan results and one of the scan results.

Thanks,

The Malwarebytes scan of the evening of 9 March is fine. And do not "fret" over what is in "quarantine" area of Malwarebytes. That quarantine is "permanent lockup". No need to fret over it.
As a next step, I suggest the following:

This is for a scan with ESET Onlinescanner (free). ESET is a well-respected, well-known entity and tool.

This here you can start & once it is under way, you can leave the machine alone & let it run over-night. No need to keep watch once it starts the actual scan run.

Next, This will be a check with ESET Onlinescanner for viruses, other malware, adwares, & potentially unwanted applications.

Go to https://download.eset.com/com/eset/tools/online_scanner/latest/esetonlinescanner.exe

It will start a download of "esetonlinescanner.exe"

• Save the file to your system, such as the Downloads folder, or else to the Desktop.
• Go to the saved file, and double click it to get it started.

 

• When presented with the initial ESET options, click on "Computer Scan".
• Next, when prompted by Windows, allow it to start by clicking Yes
• When prompted for scan type, Click on CUSTOM scan  and select C drive to be scanned
• Look at & tick ( select ) the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"
• and click on Start scan button.

Have patience. The entire process may take an hour or more. There is an initial update download.
There is a progress window display. You may step away from machine &. Let it be. That is, once it is under way, you should leave it running. It will run for several hours.

• At screen "Detections occurred and resolved" click on blue button "View detected results"
• On next screen, at lower left, click on blue "Save scan log"
• View where file is to be saved. Provide a meaningful name for the "File name:"
• On last screen, set to Off (left) the option for Periodic scanning
• Click "save and continue"
• Please attach the report file so I can review

Hi Maurice,

 

I've done the eset scan.  It found no suspicious items per the attached.

 

Thanks

Bravo. Thank you. Now a different scan with another security scanner. 

This with Kaspersky KVRT tool.

Download Kaspersky Virus Removal Tool (KVRT) from here: https://www.kaspersky.com/downloads/thank-you/free-virus-removal-tool and save to your Desktop.

Next, Select the Windows Key and R Key together, the "Run" box should open.



Drag and Drop KVRT.exe into the Run Box.



C:\Users\Danielle\DESKTOP\KVRT.exe will now show in the run box.



add

-dontencrypt

Note the space between KVRT.exe and -dontencrypt

C:\Users\Danielle\DESKTOP\KVRT.exe -dontencrypt 

should now show in the Run box.



That addendum to the run command is very important.


To start the scan select OK in the "Run" box.



The Windows Protected your PC window "may" open, IF SO then select "More Info"



A new Window will open, select "Run anyway"



A EULA window will open, tick both confirmation boxes then select "Accept"



In the new window select "Change Parameters"

 

• In the new window ensure the following boxes are ticked:
  • System memory
  • Startup objects
  • Boot sectors
  • System drive

• Then select "OK" and „Start scan“.

The Kaspersky tool is very thorough so will take a considerable time to complete, please allow it to finish. Also while Kaspersky runs do not use your PC for anything else..

• completed: If entries are found, there will be options to choose. If "Cure" is offered, leave as it is. For any other options change to "Delete", then select "Continue".
• Usually, your system needs a reboot to finish the removal process.
• Logfiles can be found on your systemdrive (usually C: ), similar like this:

Reports are saved here C:\KVRT_data\Reports and look similar to this report_20230311_103000.klr

• Right click direct onto those reports, select > open with > Notepad.
• Save the files and attach them with your next reply

[TerryMeh]

Kaspersky scan shows nothing found.

[TerryMeh]

Ah today's malwarebytes scheduled scan just picked up a new item (which the earlier Kaspersky and eset scans apparently didn't find).  Attached

2023-03-11 results.txt

[Maurice Naggar]

Delete the OSAQEJ_2021-09.ZIP on C:\USERS\DANIELLE\DOWNLOADS

Next:  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  CUSTOM scan  & then select the C drive to be scanned.

Then start the scan. Have lots of patience. Once you start the scan & you see it started, then leave it be.  

• 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 screen display.  The only things that count are the End result at the end of the run.
• Again, any on-screen display about repeat 'infection' is not to be relied on.  Ignore those.
• We only rely on the end result that is on the log-report-file.

 

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. 

[TerryMeh]

I downloaded the Microsoft Safety Scanner but it crashes with an error "An error has occurred.  Please visit the Microsoft Safety Scanner Help Page for more details. 

The errors in the log are:

I restarted the machine, downloaded it again and it still crashes.

[AdvancedSetup]

Yes, a known issue with Microsoft Safety Scanner at the moment. Hopefully Microsoft will fix it soon.

Please wait for @Maurice Naggar to provide further instructions

Thank you @TerryMeh

@TerryMeh 

Next action step:
Disable ( turn OFF ) Fast Startup
https://www.windowscentral.com/how-disable-windows-10-fast-startup

Then restart the computer

( 2 )
Please  set File Explorer to SHOW ALL folders, all files, including Hidden ones.  Use OPTION ONE or TWO of this article
Please use this Guide

( 3 )
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 for Windows    😃.

Close Malwarebytes.

( 4 )
You only provided selected portions of the MSERT.log // I would have preferred that you had attached the entire MSERT.log file itself.
My sense is that the run worked until at the end, where "it" was prevented from communicating with the Microsoft cloud server.
Anyhow, put MSERT to the side. What follows is more like general housekeeping for this Windows 10 system.
It sort of looks like System Restore service is not enabled. This next run will turn it on.
It will also enable side-by-side protection of Microsoft Defender antivirus alongside of Malwarebytes.
NOTE: The next time you need to get a ZIP statement from the bank, try using either EDGE or Firefox browser in lieu of just Chrome.

Please run the following custom script. Read all of this before you start. Please Close all open work.

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

Farbar program :  is FRSTENGLISH.exe

Please download the attached fixlist.txt file and save it to C:\Users\Danielle\Downloads

Fixlist.txt < - - - -

NOTE. It's important that both files, FRSTENGLISH, and fixlist.txt are in the same location or the fix will not work.

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.

Use File Explorer to go to the Downloads folder

RIGHT-Click on   FRSTENGLISH and select

RUN as Administrator

and reply YES to allow it to go forward to start.

That is important so that this run has Elevated Administrator rights !!

NEXT press the Fix button just once and wait.
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 on the Downloads folder (Fixlog.txt) . Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

NOTE-1:  This custom script 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 reset the Winsock.  It will attempt to clear all Cache and history on web browsers. Depending on the speed of your computer this fix may take 40-50 minutes or more.

The system will be rebooted after the fix has run. Attach FIXLOG.txt with next reply.
