I downloaded a cracked game, that had a tool to disable windows defender, i deleted the game and the files but windows defender doesn't open now.

Hello  

I will guide you along on looking for remaining malware. Lets keep these principles as we go along.

• "Cracked / hacked" games or apps are the LEADING cause for issues like this.
• 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.

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

Please download MALWAREBYTES MBST Support Tool

Once you start it click Advanced >>> then Gather Logs

Have patience till the run has finished.
Attach the mbst-grab-results.zip from the Desktop to your reply..

You gotta have much patience. There is not a quick fix for this situation. There will be several tasks over several separate sessions, with different tools.  Be patient. Follow all advice by this expert.
Do not do any free-wheeling loose web surfing. And no playing of any games. No banking. No shopping. This machine is now lacking any antivirus protection. It is a security risk.
These are only the first steps.

Please set File Explorer to SHOW ALL folders, all files, including Hidden ones. Use OPTION ONE or TWO of this article
Please use this Guide
 

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
https://definitionupdates.microsoft.com/download/DefinitionUpdates/safetyscanner/amd64/MSERT.exe

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.

its getting late here , can we continue tomorrow ? 

 

[Maurice Naggar]

Yes, go ahead and get your rest.

The MS Safety Scanner made 2 very fortunate cleanups   (  BUT we will have more to later)

Results Summary:
----------------
Found Ransom:BAT/DisableDefender.A!dha and Removed!
Found Trojan:Win64/NSudo!MSR and Removed!

I will be posting another reply, which you can work on tomorrow.  Get your rest.

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.
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.
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 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

sorry for being late ❤️

[Maurice Naggar]

ESET Onlinescanner did do helpful cleanups.

One other scan here.

TrendMicro HouseCall scan
from this Link

First, Download & Save to your Downloads folder the appropriate HouseCallLauncher
Once the download is complete, go to where the Housecalllauncher is saved & double-click it to start it.

The program will check with TrendMicro & do a update run.

Next it will show the Disclosure window.

Click Next to proceed.

The end user license agreement is presented.   Click the Accept radio button & click Next to proceed.

I suggest a CUSTOM scan on C drive.

IF you wish a Full scan or a Custom scan, first click on the Settings

then you can select which drives you want to include in the scan.

The default is a Quick scan.

Click Scan now when ready.

The scan progress will then be displayed.   Monitor the progress or just leave it alone until it finishes this phase.

When the scan phase has completed, if any items are tagged, you will see a list, showing  the file & its location, the classification of the threat, the type, risk, and Action option.

If you see an item that you know is safe, you can click the Action  , and select Ignore.

When all done & ready, click the Fix now button.

[Akram231]

hello I do all the instruction the scan give me there is no threats found 

now what should I do 

and how the windows security will get back because it doesn't work 

[Maurice Naggar]

One reason for not being able to see or use Microsoft Defender antivirus is, that this machine has installed RAV Endpoint Protection by Reason Cybersecurity.  Did you pay for a license for that program ? If you did not pay for it, then Uninstall that program. To do that

1. Press & hold  the Windows key on keyboard & then tap the R key   to open the Run box-window.
2. Type

appwiz.cpl

and tap Enter.
The Programs and Features window will appear.   Locate on the list "RAV Endpoint Protection".

Do a right-click on it.  Then choose Uninstall.   Let it proceed.

Exit Programs and Features, when done.
Now do a Windows Restart.
 

[Akram231]

I Uninstall the RAV Endpoint Protection and still the windows defender doesn't work 

this is always show to me when i tried to turn on the the windows defender

 

[Akram231]

and this always show to me when ever i restart or shutdown the pc

[Maurice Naggar]

Hello. When you are all caught up.... Next, I would like you to run a custom task. First, please do a Windows Restart.

Please run the following custom script. Read all of this before you start.

NOTE-1:  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 empty all temporary file areas. It attempts to run MS Defender antivirus scans.  Depending on the speed of your computer this fix may take 50-55 minutes or more.

Please Close all open work.

Farbar  FRSTENGLISH program location:   Downloads folder

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 be sure you allow to proceed forward. Wait until the GUI window shows and is ready.

Then 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 net reply.

NOTICE: For other potential outside readers, 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.

[Akram231]

this work but still windows security at a glance

Fixlog.txt

[Maurice Naggar]

Alright. Thanks for the report. The fix-run is good. There is still more research to do. Have lots of patience.  I need you to run 2 new reports.

Temporarily disable Microsoft SmartScreen to download the next software below 

I also would appreciate this report:

Download   Farbar's Service Scanner utility

and Save to your Desktop.

Right-Click on fss.exe and select Run As Administrator.

Answer Yes to ok when prompted.

If your firewall then puts out a prompt, again, allow it to run.

Once FSS is on-screen, be sure the following items are check-marked:

• Internet Services
  Windows Firewall
  System Restore
  Security Center/Action Center
  Windows Update
  Windows Defender
  Other services

  

Click on "Scan".

It will create a log (FSS.txt) in the same directory the tool is run.   Please attach that file.  

( 2 )

I would recommend getting a readout report as to update status of some key apps.
Download SecurityCheck by glax24 from here

and save the tool on the desktop.

                   If Windows's  SmartScreen block that with a message-window, then
                         Click on the MORE INFO spot and over-ride that and allow it to proceed.

                             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

When all done, you may go back to turn ON the EDGE Smartscreen protection.

Next, I would like you to run a custom task. First, please do a Windows Restart.

Please run the following custom script. Read all of this before you start.

NOTE-1:  There is an issue with 2 Windows services. The goal of this is to get those 2 back to normal. This run also rechecks the system for integrity.

Please Close all open work.

Farbar  FRSTENGLISH program location:   Downloads folder

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 be sure you allow to proceed forward. Wait until the GUI window shows and is ready.

Then press the Fix button just once and wait.

Thank you for that log. At this point, we need to do 2 things.

(  1  )

I would highly suggest to insure that this pc is all up-to-date with security updates & cumulative updates on Windows. select the Windows Start  button, and then go to Settings  > Update & Security  > Windows Update . and click Check for Updates.
Have much patience.

We need a new run. This is just a report.
Locate where you saved the FSS.EXE
Right-Click on fss.exe and select Run As Administrator.

Answer Yes to ok when prompted.

If your firewall then puts out a prompt, again, allow it to run.

Once FSS is on-screen, be sure the following items are check-marked:

Internet Services
Windows Firewall
System Restore
Security Center/Action Center
Windows Update
Windows Defender
Other services

 

Click on "Scan".

It will create a log (FSS.txt) in the same directory the tool is run.   Please attach that file.
