Cannot remove VirTool:Win32/DefenderTamperingRestore


Recommended Posts

I did something very stooopid and installed a repacked game by 'FITGIRL REPACKS'. My pc got infected by malware. I am using malwarebytes to scan my pc, which I used to clear out malwares, but there are still 4 instances of VirTool:Win32/DefenderTamperingRestore which can only be seen when I run windows defender scan and cannot be detected by malwarebytes. It is pertinent to mention that I did a previous state recovery on my pc after getting infected with that malware. Please help me!windowsdefenderpic.thumb.PNG.aa19599393caf6f9db66e55aee9c97f7.PNGvirusdetails.thumb.PNG.587c13c49bda74f4a05ca7b6099098d7.PNG

Hello. My name is Maurice. I will guide you.

First, please understand that the verbiage used by Microsoft causes mis-impressions. What is flagged is one single setting that turns off the "anti-spyware" option of Defender antivirus. That is something that is typically seen, and normal, when someone installs a non-Microsoft antivirus, like Norton Symantec, or McAfee or any other 3rd-party non-Microsoft antivirus. That one setting being off should not be assumed to be a positive sign of "infection".  That said, since you had installed some hacked app, this now is no surprise.

  • Removing pesky malware can be an involved set of tasks over separate runs. Have much patience. Follow my directions. 
  • 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.

    Do these 2 steps so that ALL folders & Files are set to SHOW, plus also, Turn OFF Windows Fast start.

Please do the following actions, so that Microsoft Defender antivirus runs side-by-side along with Malwarebytes.
Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center

Click the Security Tab. Scroll down to

"Windows Security Center"

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".
{ We want that to be set as Off   .... be sure that line's  radio-button selection is all the way to the Left.  thanks. }

This will not affect any real-time protection of the Malwarebytes for Windows    😃.

Close Malwarebytes.

The Microsoft Safety Scanner is a free Microsoft stand-alone virus scanner that can be used to scan for & remove malware or potentially unwanted items from a system. This tool does not install. It is run on-demand.

This link is for the 64-bit version of MSERT.exe . Be sure you save the file first

Upon completion of the save, 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

Launch MSERT.exe
Accept the agreement terms of Microsoft
Select CUSTOM scan
Look on Scan Options & select CUSTOM scan & then select the C drive to be scanned.

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

It is normal for the Microsoft Safety Scanner to show 'detections' during the scan process on the screen itself.

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.

Hello Maurice. Thanks for an early reply. Here is the msert.log file. Also let me explain further, when I select 'remove' and then 'start action' on these infected files, nothing happens. Also it seems that all these instnces are not different files, but is one file because I can select the 'remove' option on only one of them. the MSERT found 2 infected files during the scan but at the end of the scan, there were no infected files.

Thanks.  I would like a report set for review. This is a report only.

Please download MALWAREBYTES MBST Support Tool
Be sure it is SAVEd.

Do a RIGHT-click on mb-support-1.9.2.9nn,exe & select "Run as administrator" and reply YES and ALLOW it to proceed.

click Advanced >>> then Gather Logs

Have patience till the run has finished. It may take several minutes to fully generate the report.
Attach the mbst-grab-results.zip from the Desktop to your reply..

Need to make very sure that "Fast" start setting of Windows is turned OFF and then do a Windows RESTART.  All this is necessary so that we do not run into complications.

Please run the following custom script. Read all of this before you start. The meaning of the "Fix button" operation here is just to run a custom script just for this particular machine.

NOTE-1:  This custom 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 attempt to run some scans with Microsoft Defender antivirus. It will attempt to clear Cache files of web browsers.  It will attempt to clear temporary file areas. It rebuilds the Winsock. Depending on the speed of your computer this fix may take 50-55 minutes or more.

Please Close all open work before you actually do begin this run.

FRSTENGLISH,exe  program location:   Downloads folder. The tool is already on system. That is what we will use.

Please download the attached fixlist.txt file and save it to Downloads

Fixlist.txt <- < - - - -

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

Right-click with your mouse on  FRSTENGLISH and select "Run as Administrator" and reply Yes and allow it to proceed when prompted. That is important.

next, press the Fix button just once and wait.

You will see a green-color scroll display while FRST is running.
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 on the Downloads folder (Fixlog.txt) . Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

The system will be rebooted after the fix has run. Attach FIXLOG.txt with next reply.

NOTICE: For potential outside readers,  This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause harm.

The custom-run is good. The Windows System File Checker has made some corrections.

Windows Resource Protection found corrupt files and successfully repaired them.
This last run has completed what was originally intended.

As a next step, I suggest the following:
This is for a scan with ESET Onlinescanner (free). ESET is a well-respected, well-known entity and tool. ESET Onlinescanner checks for viruses, other malware, adwares, & potentially unwanted applications.
This here 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.

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 CUSTOM scan  and select C drive to be scanned
  • 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 occurred 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

Be sure to apply this adjustment.
