Recommended Posts

Hello @VicLop and :welcome::

While you are waiting for the next qualified/approved malware removal expert helper to weigh in on your topic, and even though you may have run the following Malwarebytes utility, or its subsets, please carefully follow these instructions:

  1. Download the Malwarebytes Support Tool.
  2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
  3. In the User Account Control (UAC) pop-up window, click Yes to continue the installation.
  4. Run the MBST Support Tool.
  5. In the left navigation pane of the Malwarebytes Support Tool, click Advanced.
  6. In the Advanced Options, click only Gather Logs. A status diagram displays the tool is Getting logs from your computer.
  7. A zip file named mbst-grab-results.zip will be saved to the Public desktop, please attach that file in your next reply to this topic. Please do NOT copy and paste.

For the short time between when you post the diagnostic logs, and when your helper weighs in, please take no further self-directed remedial actions that will invalidate the diagnostic logs you will have sent.

Thank you.

Hello @VicLop

The Microsoft Safety Scanner often finds that setting. It is recently a new feature from Microsoft and is not necessarily an infection. It is a setting that Microsoft sees as not default or optimal so it changes it back to the default.

The computer could use a bit of clean up though, so please follow the directions below.

 

[ 1 ]

Please go to Control Panel, Programs, Programs and Features, Uninstall a program

Then right-click and uninstall the following

  • Bonjour
     

 

[ 2 ]

Your current DNS Servers: 192.168.1.1

Please consider changing your default DNS server settings. Please choose one provider only

DNS is what lets users connect to websites using domain names instead of IP addresses

Pick just one of these 4 providers. And be aware that you need to modify 1 time for IPv4 & a 2nd pass for IPv6

  • Google Public DNSIPv4   8.8.8.8 and 8.8.4.4   IPv6   2001:4860:4860::8888 and 2001:4860:4860::8844
  • CloudflareIPv4   1.1.1.1 and 1.0.0.1   IPv6   2606:4700:4700::1111 and 2606:4700:4700::1001
  • OpenDNSIPv4   208.67.222.222 and 208.67.220.220  IPv6  2620:119:35::35 and 2620:119:53::53
  • DNSWATCHIPv4   84.200.69.80 and 84.200.70.40   IPv6  2001:1608:10:25::1c04:b12f and 2001:1608:10:25::9249:d69b

Did you set this up on your own?

Are you aware of it?

C:\Tweaks\TaskbarX_1.7.8.0_x64\TaskbarX.exe -tbs=2 -color=0;0;0;50 -tpop=100 -tsop=100 -as=cubiceaseinout -obas=cubiceaseinout -tbr=0 -asp=300 -ptbo=0 -stbo=0 -lr=400 -oblr=400 -sr=0 -sr2=0 -sr3=0 -ftotc=1 -rzbt=1 (No File)

Hi @AdvancedSetup !

Thanks a lot for your help, here's a recap :

1 ) Bonjour is now uninstalled.

2 ) DNS settings are also changed to Cloudflare

3) TaskbarX is a software that allowed me to modify my taskbar. But after doing a scan with Malwarebytes it put it in quarantine so I left it like that. But yes, I am aware of this software

4 ) During the scan I got an error which is attached, but otherwise I think it went fine. I have disabled Norton and Malwarebytes before starting the scan as you requested.

You can setup an exclusion to stop Malwarebytes from quarantining that program then if you want it.

Do a Restore. The next time it's detected, uncheck the file detection and click on Next and it will ask if you want to stop checking it and say Yes.

Let me have you run the following scanner. @VicLop

 

 

 

 

Please run the following ESET Online Scanner and perform a Full Scan

 

Click the following link to save the installer for ESET Online Scanner

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 started. 
  • When presented with the initial ESET screen, click on "Get Started". Read and accept the Terms of use
  • On the "Before we start..." screen chose if you want to send anonymous data and if you want to provide feedback or not, then click Continue
  • When prompted for scan type, Click on the Full Scan button
  • Enable  ( select )   the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click the Start scan button.
  • Have patience.  The entire process may take a few hours or more.
  • 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 and give it a name and location you remember.
  • If something was removed and you know it is a false postive, you may click on the blue ”Restore cleaned files”  ( in blue, at the bottom).
  • Press Continue when all done.  You should click to turn off the offer for “periodic scanning”.
  • Enable "Delete application data on closing" - You do not need to submit feedback unless you want to. Simply ignore and close the program.

 

Note: If you do need to do a File Restore from ESET please follow the directions below

[KB2915] Restore files quarantined by the ESET Online Scanner version 3

https://support.eset.com/en/kb2915-restore-files-quarantined-by-the-eset-online-scanner

 

Please attach the ESET scan log you saved at the end to your next reply

Hi @AdvancedSetup ,

The eset scan was clean, nothing was found.

For information, I haven't turned on my pc since the last scan you asked me to do and when I turned it on to do the new scan with eset, 2 apps requested access to the firewall (I was not connected to the internet during these requests for information). For safety, I did not accept them, I await your opinion. Here are the apps :

  • C:\program files (x86)\asus\armourydevice\dll\armourysocketserver\armourysocketserver.exe
  • C:\program files (x86)\asus\armourydevice\asus_framework.exe

Another question, the last time I did the scan, only my pc was connected to the internet by ethernet. During the day, I noticed from my router management application that there were 2 devices that were connected with a different mac address. There was my pc because the name and mac address matched it and there was the second which I couldn't identify. What is strange is that these 2 devices did not disconnect at the same time, my pc disconnected first and the 2 device 1 hour later approximately. After turning off my computer, I removed the plug that's why I find it even weirder. I have a little idea, but could it be the vpn connection that I made with my pc ?

For information, I had already reset my router and changed the passwords before doing the farbar scan so my pc was the only device likely to do that. After noticing this device, I reset my router as well as the passwords again. I'm waiting to see if today I would have the same problem, knowing that I didn't make a vpn connection this time.

Thank you for your help !

Difficult to say, but yes a VPN or any network device physical or virtual can have a MAC address. I wouldn't worry about it too much at this time.

Good that ESET did not find anything, let's go ahead then and run the following

 

Please download the following tool

Farbar Service Scanner and run it on the computer with the issue
http://www.bleepingcomputer.com/download/farbar-service-scanner/dl/62/

 

Make sure the following options are checked:

  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center/Action Center
  • Windows Update
  • Windows Defender

Click "Scan"

It will create a log (FSS.txt) in the same directory the tool is run.
Please attach the log to your next reply.

 

 

Then run the following as well

SecurityCheck by glax24              

I would like you to run a tool named SecurityCheck to inquire about the current security update status of some applications.

  • Download SecurityCheck by glax24: https://tools.safezone.cc/glax24/SecurityCheck/SecurityCheck.exe
  • If Microsoft SmartScreen blocks the download, click through to save the file
  • This tool is safe.   Smartscreen is overly sensitive.
  • If SmartScreen blocks the file from running click on More info and Run anyway
  • Right-click  with your mouse on the Securitycheck.exe  and select "Run as administrator"  and reply YES to allow to run & go forward
  • Wait for the scan to finish. It will open a text file named SecurityCheck.txt Close the file.  Attach it with your next reply.
  • You can find this file in a folder called SecurityCheck, C:\SecurityCheck\SecurityCheck.txt

Hi @AdvancedSetup,

For some reason, I can't download SecurityCheck, Firefox tells me failure. But if it is a program to check if the softwares are up to date, I don't think I need it because I plan to do a clean reset of my pc after having finished checking my pc with you. I will reinstall my apps afterwards and they will be up to date by then.

Four your information, Microsoft SmartScreen also blocked Farbar Service Scanner from running but I was able to run it by clicking on More Info -> Run anyway.

I also noticed that I didn't include the msert.log in my first post. So I add it now with the FSS.txt file.

FSS.txt msert.log

It could be from Norton that made the change. We don't do forensic work here on the forums to track down specifically how something was changed.

People are welcome to take the computer to a security company that does forensic analysis but with a cost of potentially more than $1K most people are not willing to spend the money just to verify how something got there.

We do detection, removal, and provide suggestions to help prevent infection.

The Tamper settings are recently new to Microsoft starting about a year ago
