cannot remove rootkit.fileless.mtgen


Recommended Posts

Following a routine monthly scan of my laptop, Malwarebytes Anti-Malware found a rootkit (rootk it.fileless.mtgen).  Downloaded the Malwarebytes Anti-Rootkit utility and ran that.  All seemed to be well.  However, running another scan showed that the rootkit was still there.

Have followed the advice on the Malwarebytes Forums, downloaded FRST and ran same (FRST.txt and Addition.txt attached).

Don't know what else to do,  Please help.

Hello KSBlack and welcome to Malwarebytes,

My screen name is kevinf80, i`m here to help clean up your system. Make sure to run all scans from accounts with Administrator status, continue as follows please:

Anyone other than the original starter of this thread please DO NOT follow the instructions and advice posted as replies here, my help and advice is NOT related to your system and will probably cause more harm than good...

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Run FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Please open Malwarebytes Anti-Malware.
 
  • On the Settings tab > Detection and Protection sub tab, Detection Options, tick the box "Scan for rootkits".
  • Under Non-Malware Protection sub tab Change PUP and PUM entries to Treat detections as Malware
  • Click on the Scan tab, then click on Scan Now >> . If an update is available, click the Update Now button.
  • A Threat Scan will begin.
  • When the Scan is complete Apply Actions to any found entries.
  • Wait for the prompt to restart the computer to appear (if applicable), then click on Yes.
  • After the restart once you are back at your desktop, open MBAM once more.


To get the log from Malwarebytes do the following:
 
  • Click on the History tab > Application Logs.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have three options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply
    XML file (*.xml) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply
     
  • Please use "Copy to Clipboard, then Right click to your reply > select "Paste" that will copy the log to your reply…

Yes I believe we removed the infection with FRST fix, the log you posted "fixlog.txt" has the last couple of entries missing, could you re-post that log... run the following couple of scans to ensure we have not missed any remnants...

Next,

Download AdwCleaner by Xplode onto your Desktop.
 
  • Double click on Adwcleaner.exe to run the tool.
  • Click on the Scan in the Actions box
  • Please wait fot the scan to finish..
  • When "Waiting for action.Please uncheck elements you want to keep" shows in top line..
  • Click on the Cleaning box.
  • Next click OK on the "Closing Programs" pop up box.
  • Click OK on the Information box & again OK to allow the necessary reboot
  • After restart the AdwCleaner(C*)-Notepad log will appear, please copy/paste it in your next reply. Where * is the number relative to list of scans completed...


Next,

Download Sophos Free Virus Removal Tool and save it to your desktop.
 
  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning

Kevin,

Worked my way through your suggestions (had to re-start the ADW scan when Win7 decided to update and reboot in the middle of it). 

Submitted the log to Sophos to help with their processes.

Attached are the logs you asked for (fixlog, ADW & Sophos). 

I do have some remaining concerns about my flash drives and hard drive backup.  How to I check those for infection?

Thanks very much.

How is your system responding in general, do you have any remaining issues or concerns? Regarding external hard drives and flash drives use McShield, it is free...

Please download McShield by dr_bora and save it to your desktop.
 
  • Install it on your system.
  • It will initially run a scan and show the result as a toaster by the system clock.
  • When complete plugin your ext hard drive, McShield will check it out...
  • Plug in any Flash Drives you may use, they too will be checked out.

Kevin,

The system seems to be okay (but it hadn't given any problems before).  It was idle for several weeks as I was on vacation.

What would the rootkit have been after?  Passwords, access, ransomware?

Thanks so much.  Will definitely be sending a donation.

The infection will probably have tried to harvest sensitive data, passwords etc. This was not a ransomware infection... I would recommend that you change any passwrds that you may use, specifically any with a financial impact... if you have no remaining issues or concerns clean up as follows...

Use the following Uninstaller tool to remove Sophos...

Download GeekUninstaller from here: http://www.geekuninstaller.com/download (Choose free version) Save Geek.zip to your Desktop. (Visit the Home page at that link for necessary information)

Extract Geek Uninstaller and save to your Desktop. There is no need to install, the executable is portable and can also be run from a USB if required.

Run the tool, the main GUI will populate with installed programs list,

Left click on Program name to highlight that entry.

Select Action from the Menu bar, then Uninstall from there follow the prompts.

If Uninstall fails open the "Action" menu one more time and use "Force Removal" option

Next,

Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:

 
  • Remove disinfection tools <----- this will remove tools we have used.
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection


Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…

Next,
