After virus removal by Malwarebytes my Windows 10 PC keeps restarting


Recommended Posts

Hi,

I have a very serious problem with my Windows 10 PC. Before Malwarebytes found the virus, I had been experiencing crashes of the system after few days of use. Then recently, when I have upgraded Malwarebytes to premium version, this virus that was causing this problem was quarantined and the PC doesn't crash anymore. However, what happens after few days of use is that the PC restarts automatically. I don't know how to address this problem, as I have some important settings on my system and do not want to reinstall Windows. Any help is much appreciated.

Hello @Tomko and :welcome:

 

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

Hello @Tomko

Windows 10 already comes with Windows Defender antivirus which is pretty good on it's own. Let me have you temporarily uninstall the following.

Avast Free Antivirus
Avast Secure Browser
CCleaner
Java 8 Update 131
Java SE Development Kit 8 Update 131

 

 

 

Are you sure you want this enabled or allowed? Push Notifications on your browser appear to be enabled.

https://blog.malwarebytes.com/security-world/technology/2019/01/browser-push-notifications-feature-asking-abused/

Turn notifications on or off - Google Chrome

Web Push notifications in Firefox

 

 

After you have uninstalled the items above please run the following fix. Please do not run this fix unless you've uninstalled the above items otherwise it will not run correctly

 

 

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.

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.

fixlist.txt

Thanks

Please run the FRST program again now and click on the Scan button and post back both new logs

The fix log found and corrected the following and should have removed most of the Avast entries. There are some extensions you'll need to manually remove from your browsers though.

Windows Resource Protection found corrupt files and successfully repaired them.

Okay, that still left some Avast antivirus in the logs.

Please save the attached FIXLIST.TXT file as before to the same location as the FRST program. Then run FRST and click on the FIX button.

fixlist.txt

Once the computer restarts it should have a new FIXLOG.txt file on your desktop. Please post that back.

Then run FRST again and click on the SCAN button and post back the 2 new logs one more time.

Thanks

Yes, AVAST has now been fully removed with exception of the following items which as I said before. You will need to manually go into each browser and remove the extension on your own.

 

Edge Extension: (Avast Online Security) - C:\Users\Trung\AppData\Local\Microsoft\Edge\User Data\Default\Extensions\fdgpikaaheckgdijjmepmdjjkbceakif [2021-02-28]
Edge Extension: (Avast SafePrice | Comparison, deals, coupons) - C:\Users\Trung\AppData\Local\Microsoft\Edge\User Data\Default\Extensions\phhhmbgggfifgikoihlakngnngdehhfe [2020-08-09]

FF Extension: (Avast SafePrice | Comparison, deals, coupons) - C:\Users\Trung\AppData\Roaming\Mozilla\Firefox\Profiles\joayqgy5.default-1563728327585\Extensions\sp@avast.com.xpi [2020-10-22]


BRA Extension: (Avast SafePrice | Comparison, deals, coupons) - C:\Users\Trung\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default\Extensions\eofcbnmajmjmplflapaojjnihcjkigck [2020-07-11]
BRA Extension: (Avast Online Security) - C:\Users\Trung\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default\Extensions\gomekmidlodglbbmalcneegieacbdmki [2020-06-04]

 

Has the computer restarting on its own issue been resolved now?

I have removed the Avast extensions from both Edge and Firefox. However, I couldn't find anything in the Brave browser. I tried to find the folders of the extensions but couldn't find anything. I guess we'll have to wait few days to see if the PC will restart by itself.

Thanks for your help.

Hi @AdvancedSetup

There is definitely improvement in how my OS is working now. The system doesn't restart after few days of use, however the Chrome is behaving abnormally. After few days the pages stops displaying, instead an error message is displayed. When I try to enter Task Manager in order to restart Chrome, nothing appears after a press on CTRL + ALT + DELETE. When I want to restart the computer, there is a loading cursor and black screen. So I had to reset the system manually. I think there is something broken in the OS. Since I have some settings that I want to keep, what can I do to fix this bug?

Thanks,

Tomko

Hi @AdvancedSetup

I was waiting few days to see how my computer was behaving. Unfortunately, the problem with crashing applications has returned. The system is no longer restarting on its own, but Chrome and Firefox were having issues with crashing. I got LocalBridge exe crashing on its own. I wonder if this is the issue with some kind of virus. I thought this was resolved, but looks like my system is not stable yet. Can you please provide further assistance in this case?

Thanks,

Tomko

The logs don't indicate any infections and even faulting applications are minimal.

The operating system is getting a bit old and I'd suggest you update Windows to the latest version which may help

Please visit the following page and click on the Update now button

NOTE: Depending on the size and speed of your computer this update may take upwards  of 4 hours or more to complete. Please be patient and do not use or reboot the computer on your own. Let the system update and do the reboot or ask you to reboot on it's own.
