Hello,

Reset/Repair the web browsers concerned by the issues:

• Repair Google Chrome (only the first paragraph).

and if it persists:

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
• Additionnal.txt

Send these 3 reports to the site https://pjjoint.malekal.com/ to share them.
In return, provide the 3 pjjoint links that lead 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.

Open Notepad: Press Windows + R,
In the "Run" field, type notepad and click OK.
Copy/Paste the following into it:

Reboot:

Once the text is pasted into Notepad,
Go to the "File" menu and then "Save as",
On the left, select Desktop,
In the field at the bottom, for the file name enter: fixlist.txt
Click "Save", this will create fixlist.txt on the Desktop.

Restart FRST and click on the "Fix" button
A restart may be necessary ( not mandatory )
A text file appears, copy/paste the content here in a new message.

Restart the computer.

Hello Malekal_morte
Sorry for the delay in my response
Here is the result of your last request
https://pjjoint.malekal.com/files.php?id=20171031_h7n12k6i13f10
Firstly, I no longer have the new tab displayed on the Chrome homepage for now.
But I will follow your last recommendation to reset/repair the affected browsers, therefore Chrome.
Awaiting your reply. Best regards

Hello Malekal_morte
Thank you very much for your help. However, I don't quite understand the end of your message:
"(Especially activate the LPI detections to detect parasitic and advertising programs)"
What exactly should I do? Is there an application to install?
Thank you
