Yahoo establishes itself as a search engine

Hi,

You have installed adwares and potentially unwanted programs on your PC.
Here’s the procedure to follow to remove them:

Start with this:

Download https://www.malekal.com/adwcleaner-supprimer-virus-adwares-pup/?t=33839&start= AdwCleaner (by Xplode) to your desktop.
On the AdwCleaner page, to the right, click on the grey floppy disk with the green arrow to start the download.
Run AdwCleaner, click on [Scan].
The scan may take several minutes, please wait.
Once the scan is finished, click on [Clean]

Once the cleaning is complete, a report will open. Copy/paste the contents of the report in your next response by copy/pasting.
If that doesn't work, use the site http://pjjoint.malekal.com to host the report, provide the link to the report in a new message.

Note: The report is also saved under C:\AdwCleaner[S1].txt

Then reset your browsers:
==================================
Reset your browsers or manually reconfigure your web browsers (homepage, search engine etc) as well as remove/disable unnecessary/unwanted extensions:
* Internet Explorer and add-ons/search engines: https://forum.malekal.com/viewtopic.php?t=41399&start=

Like the angel you are, you laugh creating a lightness in my chest,
Your eyes they penetrate me,
(Your answer's always 'maybe')
That's when I got up and left

You're welcome :)

Some advice:

Install Malwarebyte's Anti-Malware: https://www.malekal.com/tutoriel-malwarebyte-anti-malware/
Run regular scans with it, it’s effective.

To prevent malicious sites, you can install Blockulicious: https://forum.malekal.com/viewtopic.php?t=46656&start=

So you won’t get caught again.
