Trojan Tasker and Trojan FakeUpdate


Recommended Posts

these two trojans are repeatedly detected when i perform a scan, and i keep getting RTP reports for riskware. ive also been experiencing a repetitive issue of a powershell window opening, and found this thread describing the same issue. i was tempted to just follow the instructions they were given, but its probably a better idea to seek help here. looking forward to any help as this is causing me much anxiety, thank you

Hello @fakeyolk

 

Please run the following fix

 

NOTE: Please read all of the information below before running this fix.

  • NOTICE: This script was written specifically for this user, for use on this particular machine.
  • Running this on another machine may cause damage to your operating system that cannot be undone.

Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

Farbar program:   FRSTEnglish.exe

Save the attached file:  FIXLIST.TXT to this folder C:\Users\Hudson\Downloads\

NOTE. It's important that both files, FRSTEnglish.exe, and fixlist.txt are in the same location or the fix will not work.

Please make sure you disable any real-time antivirus or security software before running this script. Once completed, make sure you re-enable it.

 

 

Run the Farbar program with Admin rights and press the Fix button just once and wait.

The fix may possibly take up to 60 minutes to complete

If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log named Fixlog.txt in the same folder you ran the Farbar program from. Please attach that log on your next reply.

 

  1. NOTE:  This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. It will also run a disk check on the restart to ensure disk integrity.
  2. NOTE: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications may be automatically closed.
                Also, make sure you know the passwords for all websites as cookies may possibly be removed in some cases, but not all cases.
  3. NOTE: As part of this fix, it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

Thanks

Make sure the Windows Updates are done. Make sure the laptop does not sleep while Farar is running.

The script has a built in 60 minute time out. It reached that and quit.

Fixing is terminated due to reaching maximum fixing time of 60 minutes. <==== ATTENTION

Please download the FIXLIST.TXT file above and try running it again as described.

 

Thank you @fakeyolk

I didnt realize the windows updates werent done, and it seems they didnt finish because there is a download error with "Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5043076)"

Currently troubleshooting windows update and it says "Resolving Problems" - taking a while so ill get back once im able to run the fix again. Last night the fix took the entire 60 minutes, and when i restarted my laptop was when the update thing began and continued for probably another hour or more - no percentage appeared.

Ah... PowerShell.exe does not belong in that folder. That is a trick being played on the system as an exploit method.

If you're no longer using Opera we can fully remove this folder along with all files and folders

Please uninstall Opera and remove this folder.

C:\Users\Hudson\AppData\Local\Programs\Opera GX\

If you need help, please let me know.

 

Then RESTART the computer and let me know if you're still getting any alerts or signs of an infection.

I haven't gotten any alerts from malwarebytes and all scans come out clean, but the cure.it file is too big to attach to my reply. i paid attention to the tab while it ran though and it said 0 detections if that helps at all, is there another way i could send the file?

You can zip the log from Dr. Web Cureit and it should then fit to upload @fakeyolk

 

Then let's do one more AV scan from Microsoft to make sure.

 

 

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

[ 1 ]

Please make the following system changes.

  • 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.
  • Temporarily disable Microsoft SmartScreen to download software below only if needed. Make sure to turn it back on once the scans are completed.
  • Disable-Fast-Startup
  • Show-Hidden-Folders-Files-Extensions

Microsoft Safety Scanner

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 to complete.

  • 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 and saved in the log.
  • The scan may 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 and did.

 

Thank you
