Trojan.PowerShell infection


Recommended Posts

Hi! I just got infected by some virus and I'm freaking out lol!

I saw some topics on the subject and did some things to my knowledge, first I started with RKill, then I scanned with Malware Bytes Premium and ADWcleaner and quarantined the files that were found and finally I made a report with FRST, I will attach all the logs here.

The suspected program that infected me has been deleted, and the files have been quarantined, is there anything else I need to do?

Hello @Yuriileon and :welcome::

While you are waiting for the next qualified/approved malware removal expert helper to weigh in on your topic, and even though you may have run the following Malwarebytes utility, or its subsets, please carefully follow these instructions:

  1. Download the Malwarebytes Support Tool.
  2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
  3. In the User Account Control (UAC) pop-up window, click Yes to continue the installation.
  4. Run the MBST Support Tool.
  5. In the left navigation pane of the Malwarebytes Support Tool, click Advanced.
  6. In the Advanced Options, click only Gather Logs. A status diagram displays the tool is Getting logs from your computer.
  7. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please attach that file in your next reply to this topic. Please do NOT copy and paste.

For the short time between when you post the diagnostic logs, and when your helper weighs in, please take no further self-directed remedial actions that will invalidate the diagnostic logs you will have sent.

Thank you.

Let's do some more scans but yes that was probably due to junk in Sync on Chrome @Yuriileon

 

 

Microsoft Safety Scanner

Please make sure you Exit out of any other program you might have open so that the sole task is to run the following scan.   
That goes especially for web browsers, make sure all are fully exited out of and messenger programs are exited and closed as well
 

STEP 1

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

https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

STEP 2

I suggest a new scan for viruses & other malware. This may take several hours, depending on the number of files on the system and the speed of the computer.

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 the Scan Options & select the FULL scan.

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

  • 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 the screen display.  The only things that count are the End result at the end of the run.
  • The scan will take several hours.  Leave it alone. It will remove any other remaining threats as it goes along.  Take a very long break, do your normal personal errands .....just do not use the computer during this scan.

This is likely to run for many hours as previously mentioned  ( depending on the number of files on your machine & the speed of the hardware.)

The log is named MSERT.log  and the log will be at C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

It is normal for the Microsoft Safety Scanner to show detections during the scan process.

It is scanning for basically all bread crumbs or traces of files and registry entries that "might" be or have been part of some infection or previous infection.

That DOES NOT mean the computer is infected. Once the scan has been completed it uploads the log to their Cloud service which then uses Artificial Intelligence to determine if in fact any of the traces are an infection or not.

Then it writes into the log on your computer what it found.

 

Thank you

That log looks good. Nothing found.

Please run the following @Yuriileon

 

 

SecurityCheck by glax24              

I would like you to run a tool named SecurityCheck to inquire about the current security update status of some applications.

  • Download SecurityCheck by glax24: https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • If Microsoft SmartScreen blocks the download, click through to save the file
  • This tool is safe.   Smartscreen is overly sensitive.
  • If SmartScreen blocks the file from running click on More info and Run anyway
  • Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"  and reply YES to allow to run & go forward
  • Wait for the scan to finish. It will open a text file named SecurityCheck.txt Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

The following programs need to be updated according to that log @Yuriileon

 

Discord v.1.0.9006 Warning! Download Update
VLC media player v.3.0.17.4 Warning! Download Update

 

Also, the logs shows that your System Protection for System Restores is disabled. I would recommend that you enable that and create a new Restore Point

Thank you

Great, unless there is something else we should be about done here.

 

Let's go ahead and do some clean-up work and remove the tools and logs we've run.

Please download KpRm by kernel-panik and save it to your desktop.

  • right-click kprm_(version).exe and select Run as Administrator.
  • Read and accept the disclaimer.
  • When the tool opens, ensure all boxes under Actions are checked.
  • Under Delete Quarantines select Delete Now, then click Run.
  • Once complete, click OK.
  • A log will open in Notepad titled kprm-(date).txt.
  • Please attach that file to your next reply. (not compulsory)
