Microsoft edge "custom search bar" extension redirects to rb.fastsearch.me


Recommended Posts

A browser extension called "custom search bar" keeps redirecting me to rb.fastsearch.me before sending me to the requested site.

Malwarebytes blocks it from redirecting me to it, but nothing lets me remove it. I cant remove it through edge because its "controlled by my organization" (my pc isnt linked to any organization)

Thank you, Pete.  Hello @xleepy I'll look forward to getting the Farbar FRST reports. By the way, there should be a way to drill down thru Settings of Edge to possibly "disable" the bad extension

I have tried to Disable the extension but since it says "managed by your organisation" i cannot disable it without any sort of bypass. Here are the FRST docs

FRST.txt Addition.txt

We will get the EDGE browser search redirect fixed. There is a combo of 2 factors involved. One is a policy restriction as to the Edge browser. The 2nd is the setting of the Edge Deafultsearch URL setting. I need you to do 2 basic starter steps. 

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

Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center

Click the Security Tab. Scroll down to

"Windows Security Center"

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".
{ We want that to be set as Off   .... be sure that line's  radio-button selection is all the way to the Left.  thanks. }

This will not affect any real-time protection of the Malwarebytes for Windows    😃.

Close Malwarebytes.

This custom script is for  XLEEPY  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. This is really just housekeping with small cleanups.

We will use FRST64  on the Downloads  folder to run a custom script.    The system will be rebooted after the script has run.

This custom script has some specific things, plus some general aspect to help the system overall.  

NOTE-1:  This script will  run a scan using System File Checker to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. .  It will clear the cache files on Brave and Edge browsers.

  • It will clear the EDGE browser DefaultSearchURL
  • It will update Microsoft Defender antivirus and attempt to do one Quick scan

Please be sure to Save this attachment Fixlist.txt to Downloads folder. The FRST64 & Fixlist work as a pair & need to be in same folder.

Fixlist.txt       <<< - - - - -

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


Start FRST64    .  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. 
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.

CHKDSK will run a disc check on next machine Restart.

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

A printer hasnt been configured to the system, nor any peripherals other than keyboard mouse and monitor. Another system on my local network has, but not in a few years.
The fixlog is attached below and the attachment doesnt show up anymore. Problem solved?

upon running the second script with frst fix the extension reappeared.
when i use a shortcut from the edge home screen the redirect doesnt occur, only when i use the top url search the redirect occurs and MB flags it with
"Website blocked due to pup

Website blocked: rb.fastsearch.me" (also still controlled by organisation)

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

Please download MALWAREBYTES 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

Thank you for the zip report. Now then, since you describe some potential adware issue:

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.
