Properties extension virus


Go to solution Solved by Maurice Naggar,

Recommended Posts

For the past 2 weeks, this properties virus keeps popping up whenever I open google for a couple of minutes. It opens command prompt for a couple of seconds, restarts google and defaults my search to bing. I was able to find the file named "chrome_settings" on my hard drive containing a javascript file, json file and a png file. I thought I solved it after i permanntly deleted it, but it reinstalls itself somehow. I have run Malwarebytes multiple times and ccleaner too but both of them say they detected nothing. Hopefully someone can help me out here.

Hello :welcome:  @Mathias11m

I will guide you along on looking for remaining malware. Lets keep these principles as we go along.

  • Removing malware can be unpredictable
  • Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Only run the tools I guide you to.
  • Do not run online games while case is on-going. Do not do any free-wheeling web-surfing.
  • The removal of malware isn't instantaneous, please be patient.
  • Cracked or or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
  • Please stick with me until I give you the "all clear".
  • If your system is running Discord, please be sure to Exit out of it while this case is on-going.

You mentioned that you have scanned with Malwarebytes & also Adwcleaner.

I need more information from this machine. Close as many other apps as you can before running this report. 

I would like a report set for review.   This is a report only.

Please download MALWAREBYRES MBST Support Tool

Once you start it click Advanced >>> then   Gather Logs

 Have patience till the run has finished.

Upload an archive once it is done. Attach the mbst-grab-results.zip from the Desktop.

 

  • Please attach  mbst-grab-results.zip    to your reply
  • The IP block actions by Malwarebytes are keeping the machine safe from potential threats.
  • We do need the support zip reports to see more detail  ( the screen grabs just do not have full details + those screens give no clue as to what processes are running.

Hello. Thank you for the report. Next step: Please  set File Explorer to SHOW ALL folders, all files, including Hidden ones.  Use OPTION ONE or TWO of this article
Please use thuis guide https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

This custom script is for  Mathias11m  only / for this machine only.

Be very sure to Save any work-files you have open at this point. Close & Save any open edits, if any. Next, a custom script to do  checks & some  cleanups. 

We will use FRSTENGLISH  on the Downloads  folder to run a custom script.    The system will be rebooted after the script has run.

NOTE-1:  This script will  check on Microsoft Defender & make sure it is up-to-date & do one Quick Scan. It will also get a status check on services. It will run Windows SFC & DISM to check integrity. It will rebuild the Winsock. It will remove the rogue scheduled task that is at heart of the issue.

Please be sure to Close any open work files, documents,  any apps you started yourself  before starting this.

  • Please save the (attached file named) FIXLIST.txt   to the   Downloads   folder

Fixlist.txt     <<< - - - - -

Then, Start the Windows Explorer and then, go  to the Downloads   folder.


RIGHT click on FRSTENGLISH   and select RUN as Administrator and allow it to proceed.  Reply YES when prompted to allow to run.
  to run the tool. If the tool warns you the version is outdated, please download and run the updated version.
IF Windows prompts you about running this, select YES to allow it to proceed.

  • IF you get a block message from Windows about this tool......

               click line More info information on that screen
               and click button Run anyway on next screen.

  • on the FRST window:

Click the Fix button just once, and wait.

PLEASE have lots and lots of patience when this starts. You will see a green progress bar start. Lots of patience. 
If you receive a message that a reboot is required, please make sure you allow it to restart normally.
The tool will complete its run after restart.
When finished, the tool will make a log ( Fixlog.txt) in the same location from where it was run.

Please attach the FIXLOG.txt with your next reply later, at your next opportunity. Stick with me.

After this run, you will want to do a new scan with Malwarebytes.

Hi, The Windows SFC System File Checker did make some corrections. The custom run did what was intended.
I am glad to know that this last Malwarebytes scan found no malware.

Let's do one scan with Malwarebytes Adwcleaner to check for adwares. Just before pressing that "scan" button, be sure that Chrome & Edge, or other web browser are Closed.

It will not take much time,

First download & save it

https://support.malwarebytes.com/hc/en-us/articles/360038520054-Download-and-install-Malwarebytes-AdwCleaner

Then be sure to close all web browsers.

Then go to where the EXE file is saved. Start Adwcleaner.  Then do a scan with Adwcleaner

https://support.malwarebytes.com/hc/en-us/articles/360038520114-Malwarebytes-AdwCleaner-scan-and-clean

Attach the clean log. 😁

I am very glad that I had you run Adwcleaner !! so glad ! It found and removed a serious P U P ( a rogue) named Santivirus ( a.k.a Segurazo).  See https://blog.malwarebytes.com/detections/pup-optional-segurazo/
So fortunate.
I would very much like you to run one other scan.

Download and run the following scanner as well. You may need to send them your email address to get a link to download the scanner.

Sophos Scan & Clean

Download Sophos Scan & Clean 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 close all other open applications and Do Not use your PC whilst the scan is in progress... This scan is very thorough so it may take several hours to complete, please be patient...

 

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)

 

Attach the results in your next 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...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 under this sub-folder: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs 

Please attach that log on your next reply

Hello. I am glad to have worked with you. Your system is good-to-go.
We can proceed with cleanup of tools we used.

To remove the FRSTENGLISH tool & its work files, do this. Go to your Downloads folder. Do a RIGHT-click on FRSTENGLISH.exe & select RENAME & then change it to

UNINSTALL.exe

.
Then run that ( double click on it) to begin the cleanup process.

Delete mb-support-1.8.n.nnn.exe
Delete mbst-grab-results.zip on the Desktop.

Adwcleaner you may keep and use as needed.
Any other download file I had you download, you may delete.
Consider using PatchMyPC, keep all your software up-to-date - https://patchmypc.com/home-updater#download

Keep your system and programs up to date. Several programs release security updates on a regular basis to patch vulnerabilities. Keeping your software patched up prevents attackers from being able to exploit them to drop malware.

I am marking this case for closure.
I wish you all the best. Stay safe.
Sincerely.

Maurice
