Strange Malware/Connections


Go to solution Solved by ericr3305,

Recommended Posts

Hello folks,

 

Recently I have been dealing with some highly stubborn malware. Nothing I do seems to be able to remove it. I have tried running several scans with various different antiviruses, primarily Malwarebytes Premium. Windows Defender regularly (every couple of minutes) is quarantining this (see attached image 0d8) and Malwarebytes Premium is now constantly detecting this outbound connection as a trojan. I have no idea what this is and have never seen it before (see attached image f73.) I'm not even sure where to start at this point, so any help would be appreciated. I'm running Windows 11 22H2.

 

Thanks

Hello :welcome: 

I will guide you along on looking for remaining malware. Lets keep these principles as we go along.

  • The IP block actions by Malwarebytes are keeping the machine safe from potential threats.
  • Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Only run the tools I guide you to.
  • Do not run online games while case is on-going. Do not do any free-wheeling web-surfing.
  • The removal of malware isn't instantaneous, please be patient.
  • Cracked or or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
  • Please stick with me until I give you the "all clear".
  • If your system is running Discord, please be sure to Exit out of it while this case is on-going.

I would like 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

 Have patience till the run has finished.

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
  • I do need the support zip reports to see more detail  ( the screen grabs just do not have full details
  • The BLOCK notices from Malwarebytes are keeping the pc SAFE from potential harm.

Hi. A ) No need to use the "quote" when initiating a reply. You and I are the only ones on this thread.

B )

Take these actions so that Windows 11 is set to show all hidden files and folders.
Open File Explorer from the taskbar.

Select View > Show > Hidden items.

Select View ShowFile name extensions

C )

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 prompted for scan type, Click on custom to select the C drive for scanning

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"

Hi. 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.

user posted image

Drag and Drop KVRT.exe into the Run Box.

user posted image

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

user posted image

add 
-dontencrypt

 Note the space between KVRT.exe and -dontencrypt

C:\Users\roblo\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 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_20221130_103821.klr

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

Hi. Thank you. The last run of Kaspersky found no malware. The Kaspersky run preceding that is a helpful. It did some cleanup.
Now, some other steps.
( 1 )
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.

( 2 )
download & save a new copy of the tool FRST64.exe from this link https://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/dl/82/
Be sure it is saved to the DOWNLOADS folder.

( 3 )

This next custom-fix is mainly intended to run Windows' SFC & DISM to check the system for integrity. To clear temporary cache on Edge & Chrome & Firefox. To rebuild the Winsock. To attempt to check the system with Microsoft Defender antivirus. It will delete temporary file areas. It will remove rogue scheduled-task files that apparently are at the source of the trigger of block notice.

This is not a cure-all. However hopefully it will help clear the major issues-at-hand.

This custom script is for  Ericr3305  only / for this machine only.

  • Please save the (attached file named) FIXLIST.txt   to the   Downloads   folder

Fixlist.txt <<< - - - - -

Please be sure to Close any open work files, documents,  any apps you started yourself  before starting this. THIS run will do a Windows RESTART. Once it starts it will auto-close any other running app.

We will use FRST64.exe  on the Downloads folder     to run a custom script .    The system will be rebooted after the script has run. 

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


RIGHT click on FRST64.exe    and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.

  •    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 patience when this starts. You will see a green progress bar start. Lots of patience.  Please attach the Fixlog.txt with your next reply. 

Please only attach logs, reports as we go along.

Thank you for the fix-script run log. The run is good. The MS Defender antivirus is in good sate. And its history log had no entries as far as threats after 26 November. The system is in a better state.

[  2   Do a custom scan with Microsoft Defender Antivirus ]

Just want to do a visual check in Windows Security to see (visually) that Microsoft Defender is on , and to do a Custom scan.

From the Windows Start menu, select Settings, then select Update and Security.

Next, look at the left-side menu & select Windows Security

Next, In Windows Security section: Click on the grey button Open Windows Security

Now, click on the shield Virus and threat protection

Look to see that Microsoft Defender is shown & available for use.

On the next display, look at all the options.  Look down the list and see "Check for Updates" .

You should click on that to have the system check for updates for Windows Defender.  Watch & wait for that to complete.

Please also note that the Scan options (all) can be displayed by clicking on Scan options.   Click that & select CUSTOM scan & then pick the C drive  & have it go forward.

Once it has started the scan phase, you can go take a long break.   Let me know the results.

That is most excellent. 👈☀️ Previous to that, Kaspersky KVRT was run, and before that ESET Online scanner was run.

Let's do one scan with Malwarebytes Adwcleaner to check for adwares. Just before pressing that "scan" button, be sure that Chrome & Edge, or other web browser are Closed.

It will not take much time, But do read all of this write-up first so that you fully understand the concept of this special run.

First download & save it
guide & download link

Then be sure to close all web browsers after the download & before launching the tool.

Then go to where the EXE file is saved. Start Adwcleaner.
Reply YES at the Windows prompt to allow the program to proceed and make changes. That is the usual Windows security prompt.

Take your time and go careful. There are some preliminary selections to be set ....before pressing any 'scan' button.

When AdwCleaner starts, on the left side of the window, click on “Settings” and then enable these repair actions on that tab-window
by clicking their button to the far-right for ON status

Delete IFEO keys
Delete tracing keys
Delete Prefecth files
Reset Proxy
Reset IE Policies
Reset Chrome policies
Reset Winsock

Now On the left side of the AdwCleaner window, click on “Dashboard” and then click “Scan” to perform a computer scan.

This can take several minutes.
When the AdwCleaner scan is completed it will display all of the items it has found. Click on the “Quarantine” button To remove what it found.

AdwCleaner will now prompt you to save any open files or data as the program will need to close any open programs before it starts to clean. 
Click on the “Continue” button to finish the removal process.

Guide article

Attach the clean log from Adwcleaner when all completed.

Alright. 

Do a new scan with Malwarebytes for Windows.

Do a Check for Update using the Malwarebytes Settings >> General tab.

See this Support Guide https://support.malwarebytes.com/hc/en-us/articles/360042187934-Check-for-updates-in-Malwarebytes-for-Windows

When it shows a new version available, Accept it and let it proceed forward.  Be sure it succeeds.

If prompted to do a Restart, just please follow all directions.

Let me know how that goes.    Next, the Malwarebytes scan.

Next click the blue button marked Scan.

 

When the scan phase is done, be real sure you Review and have all detected lines items (if any are foundcheck-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).         <<<<     💢

MB4_scan_tick_ALL.jpg.954dd31097351eba2c305a1321a445d6.jpg

 

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.

MB4_scan_all_Quarantine2.jpg.99b8d9b73d90d347577ae0826ac406b1.jpg

 


Then, locate the Scan run report;  export out a copy;  & then attach in with your  reply.
See https://support.malwarebytes.com/hc/en-us/articles/360038479194-View-Reports-and-History-in-Malwarebytes-for-Windows-v4

As well, also tell me, Any "block notices" today from Malwarebytes ?

I think the block notices may have had something to do with NordVPN. It came bundled when I bought Malwarebytes Premium on Newegg. I ended up uninstalling that and then the block notices immediately stopped. I have no need for a VPN anyway, just figured I'd try it out since it came free. Anyhow, the threat scan completed with no findings. Here's the log.

Obviously, the scan report from Malwarebytes is excellent. 😀And I am glad to have the good news that the Block notices have ceased. 😃
It is very interesting what you report about the Nordvpn application.

So with the cessation of the block notices, we can wrap up the case.
We can proceed with cleanup of tools we used.

To remove the FRST64 tool & its work files, do this. Go to your Downloads folder. Do a RIGHT-click on FRST64.exe & select RENAME & then change it to

UNINSTALL.exe

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

Delete mb-support-1.8.7.918.exe
Delete mbst-grab-results.zip on the Desktop.
Delete msert.exe
Delete Esetonlinescanner.exe

Adwcleaner you may keep and use as needed.
Any other download file I had you download, you may delete.
Consider using PatchMyPC, keep all your software up-to-date - https://patchmypc.com/home-updater#download

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.

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

Maurice
