Malware removal help required.

Hi, This is going to be a long description so please bear with me.

Yesterday(On 30th May 2022) at around 5 pm, I downloaded a software "GCleaner" which turned out to be a Malware app. I immediately disconnected my internet after I realised that it's a Malware. My anti virus didn't detect it earlier. But after some time, when I connected my internet connection, I started getting a notification from my antivirus saying "Threat secured,
We've safely aborted connection on 104.155.207.188 because it was infected
with URL:Blacklist" and my pc got into an unending restarting loop. It's stopped restarting when I deactivated my antivirus and disconnected the pc from internet. Then I searched for the malicious app in the control panel but it was not listed there. I searched on Google regarding this malware and found that it's probably a rootkit malware. I found some relatable posts in the community asking us to install FRST64, AdwCleaner, Malwarebytes.

I installed all those apps and run FRST first and In the FRST and Addition files, I found that exactly at 17:07 some files were created in my pc which are highly questionable.

I then ran Malwarebytes and found some malwares detected in my pc. I quarantined them and ran the scan once again. I didn't detect anything this time.

After that I ran AdwCleaner and found out that there some PUP.Optional.Legacy Trovi.com virus in my Chrome browser. I tried quarantining them. I showed that the virus has been removed but when I scan again, I found out that it's getting detected once again.
So, I had to manually remove it.

After all these steps, I ran FRST again. But I found the questionable files were not removed. This time I tried removing them manually in the explorer. All but 2 of those files were removed. One of the file was 4y63267.sys and it was situated in the System32\drivers folder. This file is read and write protected so it doesn't delete even using cmd in safemode. Everytime I tried deleting, it shows Access is denied. I even tried TronScript, Unlocker and boot disks to delete it but this file isn't even detected there.
Another file is in System32\Tasks\Service.

Please help me remove these remaining 2 malwares.

Good day, @amiyangshu

 

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.

Note: If the tool warned you about an outdated version please download and run the updated version.

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 also run a disk check on the restart to ensure disk integrity. Depending on the speed of your computer this fix may take 30 minutes or more.

NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The use of an external password manager is highly recommended instead of using your browser to store passwords.

NOTE-3: As part of this fix it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

The following directories are emptied:

  • Windows Temp
  • Users Temp folders
  • Edge, IE, FF, Chrome, and Opera caches, HTML5 storages, Cookies and History
  • Recently opened files cache
  • Flash Player cache
  • Java cache
  • Steam HTML cache
  • Explorer thumbnail and icon cache
  • BITS transfer queue (qmgr*.dat files)
  • Recycle Bin

Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix.

The system will be rebooted after the fix has run.

Thanks

Do you know how to start into the Recovery Environment?

I'd like to get a copy of this file. It's locked but it maybe locked because it may belong to Avast antivirus.

C:\WINDOWS\system32\Drivers\4y63267.sys

 

It's past 1 AM for me so I'll check back on you tomorrow, but I'd really like to get a copy of that file to make sure it's not a bad file.

Thanks
