Virus added itself to defender exceptions and doesn't let me remove it


Recommended Posts

Hello, today, I wanted to install a game, long story short, it came with a virus, it came in a zip file, I ran the executable and it installed me 2 programs: "Garbage Cleaner" and a disk cleaning program, I already knew it was a virus in that moment, I deleted it, checked the task manager, many processes with random names were open, I tried to delete as much as posible, but there were 2 files I couldn't, I ran the Windows defender scan (back then I didn't have malwarebytes) and it said it didn't detect any threats besides the exceptions (I didn't add anything to the exceptions), so I checked the exceptions and found many programs that I couldn't remove from the exceptions: 

https://i.gyazo.com/d941cb222177cd751fca0d7db7938229.mp4.


I tried editing the registry, but it didn't let me remove the files from the Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths directory, so I tried running multiple scans with many antivirus programs (avast, emsisoft, kaspersky, etc) and the only one that detected something was Malwarebytes, I quarantined the items and deleted them, but the virus is still there, the exceptions are still there, my PC is running really slow, heating without doing anything and my Chrome browser shows third-party ads when I search for something in Google (they are not chrome ads). Here's the file that contained the virus:

I would really appreciate if you could help me with this issue.

Hello @Nestdot

 

Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
If you still have trouble downloading the software please click on Reveal Hidden Contents below for examples of how to allow the download.

When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download

STEP 01

  • If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
  • If you don't have Malwarebytes installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and select Scan and let it run.
  • Once the scan is completed make sure you have it quarantine any detections it finds.
  • If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Double-click to run the program
  • Accept the End User License Agreement.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, if items are found please click Quarantine.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Attach or Copy its content into your next reply.

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here each time
  • Please attach the Additions.txt log to your reply as well.
  • On your next reply, you should be attaching frst.txt and additions.txt to your post, every time.

 

Thanks

I finished doing all the scans, the malwarebytes logs I attached is the one that detected something, the scans after that said there were no threats. AdwCleaner made 2 logs, S00 Log said it was the scanning one and C00 said it was the cleaning one. I also attached the Farbar logs.
By the way, can you investigate or add the infected file I attached previously to a Malwarebytes blacklist or something? i would really appreciate it, because I got infected by a similar virus that also affected my Chrome searching.
Thanks in advance.

Okay, we'll need to do a couple more scans to get you cleaned up. That's quite a bit of junk

 

Let me have you run a different scanner to double-check. I don't expect it to find anything, but no harm in checking.

I would suggest a free scan with the ESET Online Scanner

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 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”.

I've been scanning for 4 hours now, it scanned 670,000 files and detected 14 objects, some programs aren't working fine, what can I do while the scan is in progress to help remove the malware? And also, will you be able to do something with the infected file I attached?

We'll run some other scans

 

Please download and run the following Kaspersky antivirus scanner to remove any found threats

Kaspersky Virus Removal Tool

Let me know if it finds anything or not

 

Once that is done please run the following

 

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

Please let me know the results of this scan.

The log is named MSERT.log 

the log will be at  %SYSTEMROOT%\debug\msert.log   which in most cases is

C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

Thanks

The kaspersky tool didn't detect anything, nor did the kaspersky antivirus when i first tried to scan for the virus in my first post.
The Microsoft Safety Scanner detected and removed 1 file. I attached the MSERT.log file. And please tell me, can you analyze the infected file I sent you before or not?

msert.log

Please show me a log or screenshot where you believe there is an infection.

The only thing I'm seeing over and over is junk in Google Chrome. If you clean the heck out of Chrome or even better stop using Chrome you wouldn't have it in there in the first place.

C:\Users\pc\AppData\Local\Google\Chrome\User Data\Default\Cache\f_00b758->(GZip)

Please review the following and clean up Chrome on every device you have.

 

You have not provided many any file from your system. You link to an online file and I'm not going to scan remote files that are not directly on your system.

Again, please show me screenshots or logs that show there is an obvious ongoing threat so that I can possibly better assist you.

Thanks

Now that you mention, yes, the main problem is in Chrome I see third-party ads (not from Chrome) but I'll try to clean it, could that also be the reason why my PC is slowing down?
And also, I downloaded the "online file" before, but now after many scans I deleted it, but that file is the one that caused everything.
Thanks for the help

Please run the following

 

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from.
NOTE. It's important that both files, FRST or FRST64, 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.

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.

Run FRST or FRST64 and press the Fix button just once and wait.
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 Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply.

Please also find the following files on your Desktop and attach them as well

DefenderPolicies.txt

DefenderExclusions.txt

 

fixlist.txt

 

Thanks

Okay, open REGEDIT.EXE and then browse to the following key

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Exclusions\Paths

Delete any exclusions you do not want or all of them. Then restart the computer and see if you can remove the exclusions in Windows Defender now.

I already tried that when I first started this topic and it didn't work, but now it worked and I deleted the exclusions, thank you so much, you really helped me a lot, sorry for being kind of annoying.
Also, if you can, please add the infected file to the malwarebytes database or something, thanks.

SecurityCheck by glax24              

I would like you to run a tool named SecurityCheck to inquire on the current-security-update  status  of some applications.

  • Download SecurityCheck by glax24 from here  https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • 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
