2, Malwarebytes for Windows  can detect and remove most malware with no further actions required for free.

Since it does not appear that this machine has it, go and install Malwarebytes for Windows.

We have to re-run the Malwarebytes scan. All of the found items MUST be TICKED in order to be removed. Something you did not do. 

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 sca

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).         <<<<     💢

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.

Advanced Windows Manager is a threat. If that is still installed, Uninstall it.

If there are any "Iobit" software installed, uninstal.

Do not run Roguekiller or any app on your own. No "self-medication" as far as trying to  clean current issues.

Stick with me. I will have additional tasks to be done.

  • Solution

NOTE: I have a big concern that this system is heavily infected with many, many, many rogue scheduled tasks that surely look like trojans. This is a attempt to clean most of them. There is no guarantee that this will get all of them.
I have additional concerns that the Microsoft Defender antivirus engine version is a very old one.
I have additional suspicion that this Windows operating system is very much out of date as far as Microsoft Windows Update.

Next, a custom script to do  checks & selected  cleanups. 

We will use FRST64.exe  on the Downloads folder to run a custom script.    The system will be rebooted after the script has run.

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

This custom script has some specific things, plus some general aspect to help the system overall.  Hoping it will not exceed 60 minutes in execute time.

  • Please be sure to Close any open work files, documents,  any apps you started yourself  before starting this.
  • If there are any CD / DVD / or USB-flash-thumb or USB-storage drives attached,  please disconnect any of those.
  • Please save the (attached file named) FIXLIST.txt   to the   Desktop   folder

Fixlist.txt              <<< - - - - -

Then, Start the Windows Explorer and then, go  to the Desktop    folder.


RIGHT click on FRST64.exe    and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.
  to run the tool. 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.

frst-fix.jpg.f6a25291b39a03d418acc9a3b7136900.jpg

 

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. 
If you receive a message that a reboot is required, please make sure you allow it to restart normally.
The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the FIXLOG.txt with your next reply later, at your next opportunity.  This here is not a one-shot-cure-all.  There will be more to do later.

  • AdvancedSetup changed the title to Trojan.Tasker + Trojan.Agent.E + PUP.Optional.Microleaves

Good run. Bravo. 😀  We still need to run a few more different scans to check the system. This here is just one of them.

This scan 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 so I can review

That result is very good. Continue patience. Let's do another scan.

  • 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.

That is excellent. 

I would recommend getting a report on the update status of some key apps.

                               This tool is safe.   Smartscreen is overly sensitive.

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 in a text file named SecurityType.txt. Close the file.  Attach it with your next reply.
You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

This system is good-to-go. This here is for tools cleanup.

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 may open in Notepad titled kprm-(date).txt.  I do not need it. Just close Notepad if it shows up.

Consider using PatchMyPC, keep all your software up-to-date - https://patchmypc.com/home-updater#download

Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.

I am marking this case for closure.
I wish you all the best. Stay safe.
