Malware keep coming back

Recommended Posts

Everytime I restart my laptop, I run Malwarebytes and found the exact same malware which I removed in the last session. I download the Far Bar recovery Scan tool but It didnt work ( may be I used it incorrectly)

How do I fix this?

Hello iamanh and welcome to malwarebytes....

Continue with the following:

Open Malwarebytes, select > "settings" > "security tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Single click on the target sight above scanner window.
  • In the new window select Report
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Export toTxt - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

     
  • Please use "Export to Txt" then attach the log to your reply...


Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

Or from this Mirror
 
  • Right-click on AdwCleaner.exe and select user posted imageRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Quarantine button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.


Let me see those logs in your reply...

Thank you,

Kevin....

Thanks for those logs iamanh, continue:

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

Open 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,

Download Sophos Free Virus Removal Tool and save it to your desktop.

If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....

Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...
 
  • 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
  • If any threats are found click Details, then View log file... (bottom left hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found please confirm that result....



The Virus Removal Tool scans the following areas of your computer:
  • Memory, including system memory on 32-bit (x86) versions of Windows
  • The Windows registry
  • All local hard drives, fixed and removable
  • Mapped network drives are not scanned.


Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.

Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs

Let me see those logs in your reply, also tell me if there are any remaining issues or concerns...

Thank you,

Kevin...

Does this name mean anything to you FsFilter Network it is some kind of network from Vietnam. That is related to the driver we are trying to check.

Hiya iamanh,

Try the fix once more with FRST, if the fix fails again we may need to run from the recovery environment...

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

Open 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.


Thanks,

Kevin

Hiya iamanh,

The driver is certainly protected and will not delete, the only way now is via the recovery environment.. You will need a USB flashdrive..

Please download Farbar Recovery Scan Tool from here:

http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/

save it to a USB flash drive. Ensure to get the correct version for your system, 32 bit or 64 bit

Download and also save to same Flash drive the attached file fixlist.txt (end of reply)

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

Plug the flash drive into the infected PC.

If you are using Windows 8 or 10 consult How to use the Windows 8 or 10 System Recovery Environment Command Prompt Here: http://www.howtogeek.com/126016/three-ways-to-access-the-windows-8-boot-options-menu/ to enter System Recovery Command prompt.
 
  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" and find your flash drive letter and close the notepad.
  • In the command window type e:\frst64 or e:\frst depending on your version. Press Enter Note: Replace letter e with the drive letter of your flash drive.
  • The tool will start to run.
  • When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (frst.txt) on the flash drive. Please copy and paste it to your reply.

Thank you,

Kevin

Only other option that may work is to run FRST fix with the system in Safemode. https://support.microsoft.com/en-gb/help/12376/windows-10-start-your-pc-in-safe-mode

Maybe the driver protection will not be active and the fix will then work. Give it a try and see what happens, probably the infection has blocked any road to the recovery environment. We will have to look at that later.

I have to go out now so will have to catch up later..

regards,

Kevin

Well the Fixlog does show all of the infection as "Removed" or "Moved" successfully

Has your system improved or not..?

I want to double check virustotal.com but I cant no longer find C:\Windows\27F66B0709B0.sys. Is it normal?

That driver is the crux of the infection, originally it was protected, hence we could not deal with it. Safe Mode turned off the protection and all parts of the infection were killed off...
