Riskware and Trojan removal from File: powershell.exe


Recommended Posts

Hello :welcome: 

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

  • Removing malware can be unpredictable
  • 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
  • The IP block actions by Malwarebytes are keeping the machine safe from potential threats.
  • We do need the support zip reports to see more detail  ( the screen grabs just do not have full details + those screens give no clue as to what processes are running.

The support tool report will have more detail info, which I need for review. F Y I, powershell itself is not the source of 'friction'. Also know that the web protection ( real-time protection) of Malwarebytes is keeping your machine safe from potential harm. The 'blocks'  have STOPPED the attempted outreach of the goober / pest.

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.

> One of the things to be removed is one rogue scheduled task that is the source that is cause of the main issue at hand.

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 FRSTENGLISH.exe  on the C:\Users\ramra\Downloads folder to run a custom script.    The system will be rebooted after the script has run.

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

  • 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.

  •    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. 

Please attach the FIXLOG.txt with your next reply later, at your next opportunity. We will be doing more later.

Good morning. Thank you for the report. One of the things this run has done is to remove a component of a cryptostealer.
At your next chance, on a new reply, attach this zip file C:\Users\ramra\Desktop\08.09.2022_17.35.53.zip

After you have done done, you may Delete the file 08.09.2022_17.35.53.zip
The next step I recommend is this:

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.

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 .

Now click the General tab
look down to "Manual scan performance" impact
click the selection "Manual scans take less priority ( less performamnce impact"
 

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).         <<<<     💢

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.

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

Thanks for the report files. The last Malwarebytes scan run is very beneficial. It removed a number of 'boogers'. This next tool is intended as a one-time only run. We just want to do one run with it. 

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 Full scan

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 occured 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 with next reply.

Next, a scan with a different antivirus tool. This is a one time run. This Microsoft tool is a on-demand standalone tool.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. 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. We will do more later.
