Continual Malware popup for Powershell.exe


Go to solution Solved by JSntgRvr,

Recommended Posts

Thought that I may have some malware, so wanted to run some scans.  I ran a full scan (which perusing here looks like it was maybe unnecessary over a quick scan) and removed 11 issues.  Upon restart, I noticed a PowerShell window still opening and Malwarbytes is now continually alerting me (every minute or so)  that it's blocking an outbound process from C:\SysWOW64\WindowsPowerShell\v1.0\powershell.exe

I ran another quick scan, as well as C Cleaner but haven't had any luck pinning down the issue.   I have a lot of work I've been doing on this desktop, so I'm hesitant to restore back a few months if there are other option.

Let's get the info to get the process started.

Please do the following so that we may take a closer look at your system for any possible infections.

Do these 2 steps FIRST so that files and folders are set to SHOW, plus also, Turn OFF Windows Fast Start.

Disable-Fast-Startup
https://forums.malwarebytes.com/topic/299350-disable-fast-startup/

Then please restart the computer and do the following.

WARNING: Do Not click the Repair option under Advanced unless requested by a Malwarebytes support agent or authorized helper

NOTE: The tools and the information obtained are safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  • Download the Malwarebytes Support Tool
  • In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
  • In the User Account Control pop-up window, click Yes to continue the installation
  • Run the MBST Support Tool
  • In the left navigation pane of the Malwarebytes Support Tool, click Advanced
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine
  • A zip file named mbst-grab-results.zip will be saved to the Desktop or on the hidden Public desktop (usually C:\Users\Public\Desktop), please upload that file on your next reply

    Then be patient for the next expert to take your case.

Thank you

Welcome smile.png
 
I'll be helping you with your computer.
 
Please read this post completely before beginning. If there's anything that you do not understand, please don't hesitate to ask before proceeding.
 
Please take note of the guidelines for this fix:

  • Please note that I am a volunteer. I do have a family, a career, and other endeavors that may prevent immediate responses that meet your schedule. Do note that the differences in time zones could present a problem as well. Your patience and understanding will be greatly appreciated.
  • First of all, the procedures we are about to perform are specific to your problem and should only be used on this specific computer.
  • Do not make any changes to your computer that include installing/uninstalling programs, deleting files, modifying the registry, nor running scanners or tools of any kind unless specifically requested by me.
  • Please read ALL instructions carefully and perform the steps fully and in the order they are written.
  • If things appear to be better, let me know. Just because the symptoms no longer exist as before, does not mean that you are clean.
  • Continue to read and follow my instructions until I tell you that your machine is clean.
  • If you have any questions at all, please do not hesitate to ask before performing the task that I ask of you, and please wait for my reply before you proceed.
  • Scanning with programs and reading the logs do take a fair amount of time. Again, your patience will be necessary. smile.png

Let's begin... smile.png

The support tool saved FRST64 to C:\Users\jonkr\Downloads\FRSTEnglish.exe

  • Download the enclosed file  Fixlist.txt
  • Save it in the same location FRST64.exe is saved.
  • Start FRST (FRST64) with Administrator privileges
  • This time around Press the Fix button and wait
  • When finished, a log file (Fixlog.txt) will pop up and saved in the same location the tool was ran from.

Please attach this file in your next reply.


Download AdwCleaner and save it to your desktop.

  • Double click AdwCleaner.exe to run it.

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 Prefetch files
  • Reset Proxy
  • Reset IE Policies
  • Reset Chrome policies
  • Reset Winsock
  • Reset HOSTS file
  • Click Scan Now ...
  • When the scan has finished a Scan Results window will open.
  • Click Cancel (at this point do not attempt to Quarantine anything that is found)
  • Now click the Log Files tab ...
  • Double click on the latest scan log (Scan logs have a [S0*] suffix, where * is replaced by a number, the latest scan will have the largest number)
  • A Notepad file will open containing the results of the scan.

Please attach the file in your next reply.

Hello JSntgRvr, appreciate your help! And fully understand and respect your time with volunteer work.

I've done the above steps and attached the 2 files.

One other item of note - I have not gotten the popup again notifying of the outbound PowerShell request since the restart after running MBST last night.

Thank you!

Hey there -- I made sure the repair actions were enabled, ADWCleaner found 8 results again, however when i checked the boxes and clicked quarantine, i did not get any of the followup steps you indicated.  It went straight to the scan results window, and then back to the home dashboard without any prompt to restart my PC.

Is that ok?
