Chrome unwanted google docs extension keeps reinstalling


Recommended Posts

I'm dealing with a problem where I accidentally downloaded and opened a .exe file (i still have it saved) that installed something that keeps adding a google docs extension to my chrome browser.

The docs extension prevents me from doing google searches, and who knows what else in the background, until i delete it. Malwarebytes didn't detect anything out of the ordinary, even after a 5 hour deep search on all drives.

Now, I've been through many forums and I've tried many possible solutions, but none fixed it. Here's a list of what I remember:

  1. Chrome account: Deactivated "sync" as suggested on one of your forums -> deleted all files from google cloud including all extensions -> Clean install of chrome -> opening chrome = Without logging in, the extension appeared again
  2. Checked for unwanted apps -> couldn't find anything suspicious to delete
  3. Tried Revo Uninstaller Pro and looked at Browser Extensions = Nothing is listed for chrome
  4. Tried Zemana Antimalware as suggested in one of your forums -> Found 2 possible threats -> See log attached
  5. I checked "%localappdata%" for any unwanted folders
  6. I checked "C:\Users\me\AppData\Local\Google\Chrome\User Data\Profile 2\Extensions" -> found two unwanted folder with extensions right after the clean install of chromeimage.png.86d64693eddf09b3845a3ff60e95edb4.png
  7. I checked the task scheduler on windows and didn't find anything that might cause a reinstall of the chrome file

I don't know what else to do besides a clean install of Windows, any suggestions? It has to be a local file that causes this problem, it keeps reappearing even with chrome sync off.

Many thanks,

Om

Hello  and  :welcome:     @Ominous

 

My screen name is AdvancedSetup and I will assist you with your system issues.
 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow all steps in the provided order and post back all requested logs
  • Please attach all log files to your post, unless otherwise requested
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans have been completed.
  • Temporarily disable Microsoft SmartScreen to download the software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting, and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Do not run online games while the case is ongoing. Do not do any free-wheeling or risky web-surfing.
  • Only run the tools I guide you to use. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked, Hacked, or Pirated programs are not only illegal but also can make a computer a malware victim. Having such programs installed is the easiest way to get infected. It is the leading cause of ransomware encryption. It is at times also a big source of current Trojan infections. If there are any on the system you should uninstall them before we proceed.
  • Please be patient and stick with me until I give you the "all clear". We don't want to waste your time, please don't waste ours.
  • If your system is running Discord, please be sure to Exit it while this case is ongoing.

 

To begin, please do the following so that we may take a closer look at your installation for troubleshooting. This is a report only.

NOTE: The tools and the information obtained are safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  • Download the Malwarebytes Support Tool
  • In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
  • In the User Account Control pop-up window, click Yes to continue the installation
  • Run the MBST Support Tool
  • In the left navigation pane of the Malwarebytes Support Tool, click Advanced
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine
  • A zip file named mbst-grab-results.zip will be saved to the Public desktop, please upload that file on your next reply

Thank you

Please run the following fix

Once the fix has been completed, please attach the file FIXLOG.TXT to your next reply

 

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran the Farbar FRST program 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 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.

NOTE-3: As part of this fix it will also reset the network to default settings including the firewall. If you have custom firewall rules you need to save please export or save them first before running this fix.

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
  • Discord 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.

Overall the log looks good. If found and fixed some issues.

Windows Resource Protection found corrupt files and successfully repaired them.

 

Please run the Farbar scanner again with Admin rights. Then click on SCAN and get me both new logs and we'll review for the removal of those other items.

Thank you for the logs. Please run the following

 

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
