Odd infection? Returns after computer reset?


Recommended Posts

Hi,

Please see attached MB log (at least I think this is the right one), Addition.txt and FRST.txt files.

My computer has been acting quite strangely since February.  Lots of folders with strange strings of letters and numbers being generated almost non-stop, logs that almost look like keylogs, incredibly high CPU and disk usage.  I tried every scan I could: Defender, MalwareBytes, etc.  In desperation I ultimately reset the computer entirely.  (I did the version that keeps personal files and just refreshes the Windows install.)  It helped, but not for terribly long--maybe a week or two?

I have checked every anti-virus I could since then: Defender (again, several times), McAfee, Kaspersky, BitDefender (the current one, but I've run additional Defender scans since then, including an offline removal scan on multiple occasions).  I have used CCleaner repeatedly and now have it set to run on startup.  I have reinstalled and run MalwareBytes, several others from the same company (ADW cleaner I think it's called, and a few others from that list on bleepingcomputer.com).  Everything comes up clean.  I have also disabled everything I can find in the startup menu that isn't critical (though there are a few I am unsure about and have left alone).

I use several heavy memory programs for school--PowerBI, Tableau (including two add-ins: DAXStudio and Tabular Editor), an SQL program, and Excel files that frequently have thousands of lines--and have a large set of picture files with occasional Photoshop use (a very old version of Photoshop, so theoretically smaller program, not sure).  I have Adobe Acrobat, which I recently needed to sign some electronic documents, and despite multiple attempts it now strangely won't let me uninstall (or modify).  But I try to keep the rest of the computer fairly clean.  All of these ran smoothly prior to the February issues, but all run much slower now, which is impacting my ability to do schoolwork.  (No significant gaming programs, except for Age of Empires II, which I can't remember if I've even reinstalled since the reset.  There is also an old hidden picture program (Escape Whisper Valley--very small) and a basic solitaire game from the Windows store.)

There frequently seems to be a lot of activity when the computer is in idle mode.  There does also seem to be a significant decrease in speed if I've left it on for a day or two--even after restarting, which I find strange, and even if I give it a break between powering off and powering it back on.  I've wondered if this meant it was being run remotely by some hacker, but I might just be paranoid, lol (at least I hope that's safe to laugh at).

Would you please offer any suggestions?

Thank you so much for your time.  I'll be happy to provide other logs/files as needed.

Hello @fortr

 

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

Please see attached.FRST.txt

I hope the Malwarebytes log is ok.  The new one I ran in step 1 seems to have gotten deleted somehow in the process?  (My CCleaner runs on startup, so maybe that's why after the restart before step 3?)  No history whatsoever showing in the application's Detection History section itself, so I dug around in the file explorer and pulled what I think it might be based on the time stamp.  But that was a BK file of some sort, so it wouldn't attach.  So I've tried running the MWB scan again just now (after completing step 3), but I'm not sure if it as helpful if it is out of order.  Hopefully the scan from my original post might be of value?  I don't think anything substantial changed over the weekend.  Or maybe there's another spot it might be hiding?  (That sounds crazy, I guess--something akin to the dog ate my homework.  My CCleaner ate my log file...)

Please let me know if there is anything else I can get you.

Thanks so much for your help!

PS--For some reason it shows all these extra anti-virus programs are all still enabled.  (And in my security center settings it actually lists two Bit defender ones, one right after the other.  I had to manually disable both separately, and the log seems to show at least one of them is still enabled.  And then on top of that it seems to show another of the old ones I tried when I first suspected a problem as still enabled, too.  But it doesn't exist anywhere I can find it, so there's no way I can come up with to disable it.)

I fear I may be going insane.

I'm also not sure if this is relevant, but for some reason ever since I "reset" the computer it seems to create duplicates of my files with the $ symbol ahead of them.  And most of them are sort of greyed out...  Is that normal?  Some sort of OneDrive backup thing?  Or malware?  I have tried to disable OneDrive at every corner, but it keeps coming back!

I did also find this file, which I hope is the actual log file that seemed to be missing from above.  (I compared the names, and this seems to have the right timestamps--the ones right around 16:45 today.)

Should I be concerned that the ADW scan quarantined and then seems to have deleted things like my HP CoolSense?  (I think that's the fan for the computer, so I am worried I might need it.)

I don't see an immediate obvious threat in the logs.

Let's go ahead though and do a bit of clean up for the system to make sure all is clean and working well.

Let me have you temporarily uninstall Bitdefender antivirus as well as Malwarebytes and restart the computer. Windows 10 comes with Windows Defender so it has built-in antivirus so it will still have basic protection while we clean up.

After the removal please restart the computer 2 times and then run FRST again and click the SCAN button and attach back both new logs and we'll do some clean up from there.

I'll check back on you tomorrow as it's 1:00AM here

Cheers

Thanks so much for your help, that at least makes me less panicky about the weird slowdown.

Attached are the new logs.

During the initial instructions you gave me there were several (4 or 5) built in processes that were moved to quarantine.  Were they deleted as part of that or are they still there?  I think some of them were part of my audio drivers and something called HP Coolsense.  (I think that some of the new errors shown in these logs are related to those items.)  Can/will I get them back somehow in this clean-up process?

(I'm including two sets, done a few minutes apart, because I forgot to turn the internet on the first time which meant it didn't update.  The earlier ones were just a partial scan, as I cut it off as soon as I realized it.  I'm not sure if that will matter, but I'm including that partial set just in case. The most recent ones (full scan) are the 17.06 versions.)

Thanks again!

Thank you @fortr

When you say they were quarantined. Which program removed them? Do  you have a log showing that?

 

Please go into Control Panel, Programs, Programs and Features and uninstall the following.

Bonjour
CCleaner
  (most experts no longer recommend the use)
 

 

Please download and run the following Kaspersky Antivirus Removal Tool
http://media.kaspersky.com/utilities/ConsumerUtilities/kavremvr.exe

Please download and run a Bitdefender Antivirus Removal Tool from the following link
https://www.bitdefender.com/uninstall/

 

 

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

Just fyi, I have not forgotten you!  I've had to travel unexpectedly, and I can't finish this up until early next week, but I definitely please want to do so when I get back.  For some reason my computer will no longer update Windows, and I think it must have to do with the items moved to quarantine.

I'll reach out next Tuesday or Wednesday.
