Potentially Compromised System

[Jwinebago382]

Was downloading an open-source game from the mega website, but when the download was completed, my laptop got very slow. Couldn't click out of the web browser, or get ctrl+alt+del to bring up the security screen. I figured if there was a virus coming across my internet, I ought to shut it off asap. After internet had been disconnected for 1-2 minutes, laptop returned to normal, and game was not present in my download folder, assuming it crashed when the laptop got very slow. I put the laptop in safe mode + networking (even though my internet doesn't work in this mode even though it should), and scanned my system from the admin account, here are the files:

 

Thank you and have a wonderful day

Hello @Jwinebago382

The logs don't show signs of an infection. You svchost.exe crashed which is a very important program for most operations. Please restart your computer and then run the following generic clean up and see if that helps

 

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Note: If the tool warned you about an outdated version please download and run the updated version.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

Thanks

Thank you for the fixlist,

 

I disabled windows defender, but it turned itself back on during the frst scan. As a result, I can't guarantee that the fixlist did everything it was supposed to, but I did turn it back off mid-scan so I guess we'll see. I'll run the system for a couple hours, see if there's any marked improvements. As far as I know, svchost.exe has never crashed like that before. I do know that my hard drive is damaged however, and my system has had some corruption issues in the past.

 

Is there something I can do to manage this issue of my system getting corrupt, long-term? Thanks again! Please let me know how I can donate to this organization, you're an excellent resource, been coming here for three years.

The script we ran did general cleanup and verification of the system files so that should be good.

You may want to schedule a disk check to run at least once a month if you keep having issues.

Let's go ahead and run another scan for any other potential infections.

 

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”.

 

Thanks

Hello,

 

Ran the EST scanner, took about 8 hours to finish, computer died halfway thru but after keeping it plugged in, the scan finally finished. There was no blue button available to select 'save log' but no threats were detected. I'll be sure to run a disc check soon, thank you for your help, is there some way I can donate to you?
