Trojan:Script/Wacatac.B!ml detected on my pc

Hello, before 4 days i got a notification from win defender, it said that this trojan was detected: Trojan:Script/Wacatac.B!ml. In my surprise it came from the utorrent installer file before i was able to download any torrents that could be suspicious, even though it could be an existing infection on my pc that infected the utorrent installer as well. Either way when i saw the threat it was too late because i had run the installer already.

I read that this virus was very difficult to get rid of so i started scanning with wind defender (full scan), win defender offline, and scanned with malwarebytes as well in safe mode which detected another file as a heuristic (in the same family as wacatac) that i got rid of also. i repeated more scans which didnt find anything but as i read in this forum it might have been a bad idea... So i decided to reach out for help here if someone has any idea how can i tell if my pc is still infected or not. I am attaching the original detection from win defender and also my frst scan logs in case they are useful.

Hello @Geky212 and :welcome::

Thank you for the attachment(s) you have already posted. However, please carefully follow the procedures below in the order given for the best data. Please do not forget Malwarebytes AdwCleaner in its proper order.

Although I will not be your malware removal helper, please carefully follow the steps in the order given:

Let's go ahead and run a couple of scans and get some updated logs from your system. Please read the entire post below before starting so that you're more familiar with the process.

Then, follow each step in the order provided. Unless otherwise asked, please attach all log files.

Please make the following system changes:  Please pay close attention to the instructions in all the following links.

  1. If you have not done so already, Enable System Protection and create a NEW System Restore Point.
  2. Temporarily disable your antivirus real-time protection or other security software first only if it blocks or interferes with the scans or downloads. Make sure to turn it back on once the scans are completed.
  3. Temporarily disable the overly sensitive Microsoft SmartScreen to download software below only if needed. Make sure to turn it back on once the downloads are completed.
  4. Disable-Fast-Startup. <<<<< Important.
  5. Show-Hidden-Folders-Files-Extensions.

Please run the following scans:  Please Take your time and pay close attention to the instructions in all the following links.

  1. Select the following link and run a Scan with Malwarebytes AdwCleaner with only the eight (8) requested options selected.  Report files: AdwCleaner[S00].txt and AdwCleaner[C00].txt   Please run the scan only once, correctly, to capture any and all error data. Alternate Download Source.
  2. Select the following link and run a DEFAULT Scan with Malwarebytes 5 for Windows®. Report file: Malwarebytes Scan Report YYYY-MM-DD HHMMSS.txt 
  3. >>>> Restart the computer <<<<
  4. Select the following link, and then rename FRST.exe or FRST64.exe to FRSTEnglish.exe and run a Scan with Farbar Recovery Scan Tool. Report files: FRST.txt and Addition.txt

Example image of where to click to attach the five (5) files when posting your reply to yourtopic:

The sooner you attach/send the five (5) log files, the sooner one of the Experts will weigh-in on your topic.

Thank you.

Thank you, i followed the procedure exactly as you described. Also i wanted to ask could my wi fi network be infected by this certain virus and could other devices on that network be compromised as well? Or does it affect only my pc until someone installs other malware through it? I am asking because i have a desktop pc on my network as well that has important data on it. If yes, what procedure should i follow to prevent further infections?

Furthermore, do you happen to have any resource describing how to read log files like frst's, because out of curiosity I tried reading the logs myself and i could not understand them very well. I am interested a bit in malware removal procedures and i would like to know how it is done, thank you in advance!

I am attaching the requested log files:

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... 

The following Fix will empty these folders:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Discord cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin
  • Hosts file will be reset

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns, please ask before running this fix.

The system will be rebooted after the fix has run.

FRST64 was saved as C:\Users\George Kyrtatos\Downloads\FRSTEnglish.exe

  • Download the enclosed file  Fixlist.txt
  • Save it in the same location FRST64 is saved. (FRSTEnglish.exe)
  • 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.

Dr.Web CureIt!

Please download the Dr.Web CureIt! anti-virus utility
https://free.drweb.com/

You will need to send them an email to obtain a link to download the scanner, please do so

  • The downloaded file will normally have a unique name such as:  q7a9tr4p.exe
  • Close all open applications and locate the downloaded file and double-click to run it
  • The program will take a moment to launch and bring up the License and Update screen
  • Place a check mark to agree to the terms and then click on the Continue button
  • Click the underlined link Select objects for scanning
  • On the top left click the Scanning objects that should automatically check all objects
  • Click the small wrench and make sure there is a check on Automatically apply actions to threats
  • Then click the large button on bottom right Start scanning
  • Once the scan has completed there will be a link named Open report click that and a log named cureit.log should open in Notepad
  • The log is saved in the folder named Doctor Web in the top of your user profile folders
  • Please attach that log on your next reply

There appears to be a problem, malwarebytes performed a scheduled scan in the background while i was performing the fix. Does this compromise the process? Also the fix has taken 10 to 15 mins and its still going, this is normal right?

Before i proceed with anything have a look at the log file, in case the scan from malwarebytes interrupted the process. Also a popup from defender came up i dont know if it had also potential to interrupt the fix. Have a look for yourself and tell me if it is necessary to repeat the process with all AVs turned off or if i should continue with Dr.Web.

Thanks a lot!

Thank you all very much for your help! Unfortunately i had to prepare some things for work tomorrow and i wasnt able to wait, so i uploaded all my important files to microsoft sharepoint and i clean installed ubuntu linux (thankfully the software i had to work with had a linux version).

I know that my files might be compromised and that i shouldn't download them directly but i will scan them one by one later in a virtual machine + submit them to microsoft for analysis to be safe and root out any unwanted problematic ones.

If by any chance you can answer me two last questions: does this malware spread to my home network? and what can i do to prevent the spread to my other devices such as other computers and phones?

Also i want to get into malware removal and have found in a post here some links for such courses. Is there a course that you recommend most out of all of them?

Again i appreciate you for the support and i am really sorry for wasting your time like this...
