Detected Trojan Droppers that I literally cannot get rid of


Recommended Posts

My suspicion on how this started was that a month ago when I downloaded FileZilla I accidentally didnt uncheck the bundled programs with it and I received some programs that may have been bad. One of them being "lavasoft webcompanion" which I had to go into the registry and try to delete myself after I saw malware bytes picked it up.

But the problem at the moment is that my computer is now running at a snail's pace while doing absolutely nothing at all and my left/right click buttons are not working 90% of the time or they are randomly swapping. I thought it was a virus so when I scanned it with malwarebytes (this time with rootkit scan turned on) it picked up these trojan droppers that were "supposed" to be deleted on reboot. 

KLM\SOFTWARE\WOW6432NODE\MICROSOFT\WINDOWS\CURRENTVERSION\UNINSTALL\InstallShield_{C65B26BC-5A6F-4135-9678-55A877655471}

C:\PROGRAM FILES (X86)\INSTALLSHIELD INSTALLATION INFORMATION\{C65B26BC-5A6F-4135-9678-55A877655471}\SETUP.EXE

Obviously that didn't work because I'm here confused about it. I tried reimaging my MSI laptop completely and it reinstalled windows and all that. First thing I do when it's working again is download malwarebytes and scan it with rootkit on. These same 2 things popped up again! and the computer is running at a snails pace again, left/right click buttons are all out of wack. I don't know what else I can do to get rid of it. Malwarebytes doesn't seem to be doing a very good job of helping me with it. What can I do at this point? Is my laptop completely done for? Also I don't have a mouse, I am using a trackpad only and the buttons are being messed with (likely due to the virus as it all happened at the same time).

I attached the txt file report from malwarebytes as an attachment. Please help me get control of this laptop again.

Hello @confusedcrap123

 

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

ok I did everything you said. I'd like to mention that in the original post I did a full scan with malwarebytes and when I removed the folder in the InstallShield directory and ran adw cleaner + did basic repair + rebooted my PC, the symptoms of the virus seemed to have gone away but I'm not fully convinced.

 

The attached files are from running all those things again after that reboot. I am really skeptical that I truly got rid of it that time considering it was there after a full wipe of my computer.

Please review the following link and clean up Google Chrome on all devices

 

Then once that is done please run the following scan

 

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”.

It's hard to explain but the laptop is 100% slower than what it was before yesterday and I did nothing out of the ordinary. And I still have the continuous left/right click thing happening where sometimes when I left click it just does a right click action instead. Or sometimes when I left click it just sticks and drags (acts like I'm holding it down instead of just a simple click). This didnt happen before yesterday either. Also when I right click, it takes WAY longer than it's supposed to for it to open the right click menu. Like up to several seconds sometimes. Sometimes I don't even click at all, I just move my cursor and then a right click menu appears.

 

The stuff I scanned in Malwarebytes is still in "quarantine". I don't know if deleting it from there would change anything but I am very lost. This is the most frustrating problem I have ever dealt with. This laptop isn't old or anything. I got it 4 months ago brand new and it is very powerful.

You can empty the quarantine if that would make you feel better but it's safe while in there and cannot hurt the computer.

Let's do a couple more scans just to confirm for you that the computer is not infected.

 

Please download and run the following Kaspersky antivirus scanner to remove any found threats

Kaspersky Virus Removal Tool

Let me know if it finds anything or not

 

Next, once the Kaspersky finishes run this one too.

 

The Microsoft Safety Scanner  is a free Microsoft stand-alone virus scanner that  can be used to scan for & remove malware or potentially unwanted software from a system.

The download links & the how-to-run-the tool are at this link at Microsoft

https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download

Please let me know the results of this scan.

The log is named MSERT.log 

the log will be at  %SYSTEMROOT%\debug\msert.log   which in most cases is

C:\Windows\debug\msert.log

Please attach that log with your next reply.

 

I'll check back on you again later this weekend if I can, but I'm officially off work until Monday

Thank you

kaspersky found nothing

 

MSERT quick scan found "VirTool:Win32/DefenderTamperingRestore" and said it removed it

Then I did an MSERT full scan which found "Trojan:Win32/Generic!rfn" and it said it was "partially removed". which worries me since why isnt it fully removed? What does this mean for me

Okay, please try this fix.

 

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

i did the FRST fix thing that you told me to do. It restarted the computer. Afterwards, I did the MSERT full scan again to see if anything was different but nope, same 2 things came up again.

 

Do i have to just install a fresh version of windows? Some friends of mine were recommending me to do it from a USB which seems extreme but nothing else is working :(

Please download the following scanner from Kaspersky and save it to your computer: TDSSkiller

Then watch the following video on how to use the tool and make sure to temporarily disable your security applications before running TDSSkiller.

PC Winvids - How to run Kaspersky TDSSKiller

If an infection is found please make sure to choose SKIP and post back the log in case of a False Positive detection.

Once the tool has completed scanning make sure to re-enable your other security applications.

Thank you

I'm starting to think this is just a False Positive from Microsoft.

Using Autoruns locate the following items and go ahead and delete them

\Dragon_Center_updater                File not found: C:\ProgramData\MSI\Dragon
\Microsoft\Windows\SMB\UninstallSMB1ClientTask    File not found: Unrestricted
\Microsoft\Windows\SMB\UninstallSMB1ServerTask    File not found: Unrestricted
Adobe Type Manager                File not found: atmfd.dll

 

Please restart the computer into Safe Mode and run the following.

 

Holding the Shift key down on the keyboard while clicking Power will give you an option to go into Safe Mode

Very late for me and I'm probably going to be out of town tomorrow but will check back on you if I can, otherwise I'll get back with you on Monday

i deleted the files you told me to delete in autoruns and i ran the other thing in safe mode. it didnt find anything.

 

Also the left/right click things being messed up only started a few days ago when all this stuff appeared/computer slowed down and froze up that one night before i got rid of all the other stuff i found. 

The left/right clicks are still quite messed up so I don't know what's going on there. I don't think my trackpad is the issue considering it was working before that.
