Elusive malware with task manager?

Recommended Posts

Hi,

I seem to be having similar problems to a few others that describe malware/mining programs that hide when you run anit-virus scans or open task manager. CPU often maxes to100% unless task manager is open - I find keeping it open in the background is the only way use my PC smoothly.  I've tried to follow the steps for others and attached the logs required? cheers, Eli

Hi,  @Toights     :welcome:

My name is Maurice. I will be helping and guiding you, going forward on this case.

This Windows pc is running Malwarebytes Version: 3.3.1.2183

Lets do a new install like this, so that the pc has the very latest.

Please try uninstalling and reinstalling Malwarebytes for Windows using the Support tool. Let me know if that clears up the issue or not.

Uninstall and reinstall using the Malwarebytes Support Tool
https://support.malwarebytes.com/docs/DOC-2674

 

[ 2 ]

After version 3.8.3 is installed, lets do a special scan.   First just please Close all open web browsers before pressing Scan

 

Run a scan with Malwarebytes.
Start Malwarebytes from the Start menu.

Click Settings. Then click the Protection tab.
Scroll down and lets be sure the line in SCAN OPTIONs for "Scan for rootkits" is ON
Click it to get it ON


Click the SCAN button.
Select a Threat Scan ( which should be the default).

When the scan phase is done, if any items are detected, be real sure you Review and have all detected lines items check-marked on each line on the left. That too is very critical.

Then click on Quarantine selected.

 

Be sure all items were removed.

When that is completed, kindly send the report.
In Malwarebytes.
Click the Reports button ( on the left )
Look for the "Scan Report" that has the most recent Date and time.

When located, click the check box for it and click on View Report.
Then click the Export button at the bottom left.
Then select Text File (*.txt)

Put in a name for that file and remember where the file is created.

Then attach that file with your reply. Thank you.

Hi,  Thanks for that report.  That is a re-assuring result.

[ 1 ]

This pc has Norton Security.   Can you Close all web browsers;   then run a scan with Norton Security

Let me know what it reports.

 

[ 2 ]

After that is done, please do the following.

Delete the Adwcleaner  that is cuttently on this pc.   Then

I  would suggest to download, Save, and then run Malwarebytes ADWCLEANER.

Please close Chrome and all other open web browsers after you have saved the Adwcleaner and before you start Adwcleaner.

 

Please download  Malwarebytes AdwCleaner from here:
Click the blue Download button.   ( do not pay attention to the other text displayed on that screen).

Be sure to Save the file first, to your system.  Saving to the Downloads folder should be the default on your system.

 

Go to the folder where you saved Adwcleaner. Double click AdwcleanerGUI  to start it.

At the prompt for license agreement, review and then click on I agree.

 

You will then see a main screen for Adwcleaner. ( if you do not see it right away, minimized the other open windows, so you can see Adwcleaner).

Then click on Dashboard button.

Click the blue button "Scan Now".

 

allow it a few minutes to finish the Scan.   Let it remove what it finds.

NOTE:  When it comes to the section "Pre-installed applications"   You can skip that.

Please find and send the Adwcleaner "C" clean report.

In Adwcleaner, click the "Reports" button.  Look at the list of reports for the latest date & type "Clean".

Double Click that line & it will open in Notepad.   Save the file to your system and then Attach that with your reply.

Thanks.  Keep me advised.

1.

I ran 2 different scans with Norton, first a Power Eraser rootkit scan which detected 5 threats (although two were from FRST) and repaired the other 3. Then I ran a full systen standard scan, the logs for that are attached but the power eraser is in html.

2.

Removed previous Adwcleaner and downloaded/installed from link as per your instructions. Ran the scan, it found nothing. I have attached the most recent Clean log, there are 3 clean logs in total from the past few weeks while trying to sort this on my own. Would the other 2 help?

Thanks.    But the Adwcleaner report is from June 28.

The Norton run of July 19 found nothing to be flagged.   Total security risks detected: 0
   Total items resolved: 0
   Total items that require attention: 0

 

The Malwarebytes for Windows scan of the 18th found no malware.

Ir is not clear why the CPU usage stats are an issue here on this box.

It could be the auto-started applications "load"  when Windows starts up.  To that end, I will suggest later some research steps for you.

It could also be that some Windows system services are having some issue.  To that end I will recommend you get this Windows updated to Version Build 1903.

By the way, the Windows "System Restore" service is off.  You need to turn it back ON.

See  https://www.tenforums.com/tutorials/4533-turn-off-system-protection-drives-windows-10-a.html

 

For now, a special scan at Microsoft.

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

 

Let me know the result of this.

Alrighty, I'm back.

Firstly, this may sound silly but there is an actual problem? Can you see from the logs I've posted that something is eating my CPU and I'm not just paranoid? Without Task Manager open, the CPU seems to max out still so the problem still persists.

System restore is now on and I can't download the Microsoft Safety Scanner. The download constantly fails. I've tried both Firefox and Edge but it won't work?

Attached is screenshots of task manager ~1-2 seconds after opening before it begins to run normally again.

 

I've also run Malwarebytes scans and Adwcleaner again several times. Adwcleaner did find and clean something a few days ago, and froze while doing so. Here are the logs and a screencap:

Thanks for the adwcleaner scan report.

What we can do is running some additional, different scans.  Much patience is required.  Plus it is expected that you will make update replies in a timely manner, as much as possible.  If 3 or more days go by without news, we may consider the case abandonned.  If you will be away for a long time, try to let me know ahead of time.

 

Lets start with these.

[ 1 ]

Close as many browser windows as much as possible, before this next scan.

Download,  be sure to SAVE, then RUN the Microsoft Malicious Software Removal Tool

https://www.microsoft.com/en-us/download/malicious-software-removal-tool-details.aspx

 

[ 2 ]

I would suggest a free scan with the ESET Online Scanner
Go to https://www.eset.com/us/home/online-scanner/

Look on the right side of the page.  Click Scan Now
It will start a download of "esetonlinescanner_enu.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
Click on 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 should ignore all prompts to get the ESET antivirus software program.   ( e.g.  their standard program).   You do not need to buy or get or install anything else.

When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.

Click The blue “Save scan log” to save the log.

If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at bottom).

Press Continue when all done.  You should click to off the offer for “periodic scanning”.

Cheers.

Microsoft Malicious software removal tool ran a full scan and returned a clean report. I'll run the ESET scan now and get back with results.

Hi.   Checking up on this case.   Did you do the ESET scan ?

Share this post

The ESET scan tagged 2 files that were already quarantined by Adwcleaner.  So really the ESET just found 1 P U P type file.  A Pokki.B  P U P.

PUP are not malicious malware.  They are more like unwanted pests.

So, from this scan result, I would not go with a "pc wipe".   Though that is for you to decide on, if you wish.

 

If you will run a fresh report on this pc, I will do a new review and then advise on next steps.

    Download Malwarebytes Support Tool
    
    
    Once the file is downloaded, open your Downloads folder/location of the downloaded file
    Double-click mb-support-1.4.0.623.exe to run the report
        You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
        
    Place a checkmark next to Accept License Agreement and click Next
    You will be presented with a page stating, "Get Started!"

    Do NOT use the button “Start repair” !
    Click the Advanced tab on the left column
    
    Click the Gather Logs button
    
    A progress bar will appear and the program will proceed with getting logs from your computer
   
    Upon completion, click a file named mbst-grab-results.zip will be saved to your Desktop. Click OK
    Please attach the ZIP file in your next reply.

 

Thank you.

Hi.  Thanks for the fresh support tool report.

Question:  This pc has Norton Security.   Have you run a thorough scan with Norton ?  what was the result ?

 

The following is a script to do some housekeeping to delete temporary cache files.

Please Close and save any open work files before you start this next step.  It will involve a Windows Restart at the end of it.

I am sending a   custom Fix script which is going to be used by the FRSTENGLISH tool. They will both work together as a pair.

Please RIGHT-click the (attached file named) FIXLIST and select SAVE AS and save it directly ( as is) to the Downloads folder

The tool named FRSTENGLISH.exe  is already on the Downloads folder.

Start the Windows Explorer and then, open the Downloads folder.


Double click FRSTENGLISH

  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
Click the Fix button just once, and wait.

 

FRST_Fixl.png.c4c1c0dddcc49b11fa400590f070bd5e.png

 

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. Some machines take longer than others.
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 reply.    Also advise on the situation after this run.
