Are you sure you followed the procedure correctly?
Did you delete all the Mozilla folders as indicated?

To check the computer, I invite you to perform this FRST analysis and return the reports:

Follow the FRST tutorial. ( take the time to read carefully - everything is well explained ).

Download and run the FRST scan,
Wait for the scan to finish, a message will indicate that the analysis is complete.

Three FRST reports will be generated:

• FRST.txt
• Shortcut.txt
• Additional.txt

Send these 3 reports to the site https://pjjoint.malekal.com/ to share them.
Then return the 3 pjjoint links leading to the reports here in a new response so that we can consult them.

Here is the correction to be made with FRST. You can refer to this explanatory note with screenshots.
Restart FRST and then press CTRL + Y on your keyboard.
