Virus/malware problem rebooting system


Recommended Posts

Hello. I never thought it would happen to me but guess it did. Yesterday afternoon i turned on my computer only to get greeted by a popup after it would boot into windows. The popup stated: "You are about to be logged off. Windows has encountered a critical problem and will restard automatically in one minute. Please save your work now.".

I am quite experienced with using computers but not that much around this malware/virus category, i knew that it was some sort of malware from the start, the source of it i am unsure of though, mostly because i havent been downloading anything or opening any weird emails, i dont really get those anyways for the past weeks.

I do have BitDefender installed but i had no help from it or any sort of prompt regarding this issue.

After 1 minute the system either reboots and gives me the same error over and over again or logs me off and then i get the windows screensaver having to reboot manually in order to try again. During this time i cant open anything, task manager or any sort of program, nothing. Canceling the restart with commands doesnt work either. Also during this 1 minute, the options "Restart" and "Sleep" are greyed out, i cant press on them.

What i truly find weird is that sometimes instead of getting me straight to windows i get asked for a password although i never set a password. Funny enough the password is "pass" but the problem is that by the time it actually gets to the desktop the minute passes and it restarts.
It is worth mentioning that the first couple of reboots i did NOT get that lock screen asking for a password. After around 6/7 restarts it happens. Also sometimes it appears sometimes it doesnt.

I am currently running Windows 7 because the hardware inside is meant to be machine that can play 2000's games without any compatibility issues. I am aware support for Windows 7 is over and that Windows 10 is safer.

As far as i know any MalwareBytes software cant run off an usb drive, please correct me if i am wrong, i am willing to try it because it had helped me in the past.

I will list what i have tried so far and did not work:

  • None of the Safe Modes works, i get the same popup foillowed by the restart
  • Opening task manager and it crashes like all the programs that i try to open
  • In the 1 minute that i have find the "Auto-restart" option that Windows has and uncheck it and it doesnt work
  • Most CMD lines that i tried do not work or aren't able to be completed due to the limited time
  • I have tried booting the Kaspersky Rescue Tool which scanned all the drives in the computer, found some viruses, removed them and the problem persisted
  • I have tried booting the Avast Rescue Disk and it didnt boot at all
  • I have tried using ESET SysRescue Live tool and out of all the tools i used this one seemed to take a deeper look trying to find malware, i have used it mostly on the C drive and part of the second 2 drives and it had found nothing, the problem persisted
  • I am currently using Avira Rescue System i have started a whole computer scan and i will check it when i get home although my hopes are pretty low at this point

I cannot run any exe on inside windows, all the software that i have specified above were directly installed on a usb drive as an .iso.

I am looking to either fix it temporarily and installing windows again when i have some time on my hands and finding out more about this issue if possible in order to well learn more about this part of computers and how how to avoid it.

Hello @LennyD

If the computer is that messed up then I'd suggest you do back up your personal data first. Then do a CLEAN install of Windows

If you want we can try to see else we can do if you can get the following to run

 

 

Please download 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). Please attach it to your reply as well.

Thank you

As i said, i could not run any software directly into Windows. Not even in safe mode, the computer would restart/log me off and also crash anything i would open.

I ended up reinstalling Windows, data loss was not that significant since i do not really save important files on the Windows drive. Mostly games and different programs.

I honestly can not identify where i got this malware/virus since in the past days before this happened i did not do anything that would lead to this. Mostly YouTube and playing already installed games. Very weird.

In case anyone stumbles upon this thread with the same problem, my advice to you would be to: on a second computer/laptop download different anti malware software from ESET, Norton and Avira, and by software i mean image files (.iso) that can be "burned" on a USB drive with something like Rufus, then plug it into the affected device, boot into it and let the software do it's thing.

Hopefully it will find the problem and fix it, it was no avail for my case but maybe your case is not that bad.

 

Thank you for your reply AdvancedSetup!

You could probably use a little bit of general cleaning.

If interested let me know and I can look at writing a generic cleanup script for you on Monday

 

 

After reinstalling Windows i already started a process of moving/deleting stuff from my computer. Already deleted around 100gb but theres more to come.

 

What would this script consist of? How would it work?

This is the generic reply for a cleanup script. We run DISM, SFC, and clean browsers, temp, etc. reset network back to default settings.

 

 

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
