If you are still experiencing issues with the Pro.chatxnoir.top pop-ups in Internet Explorer, Firefox or Chrome, we will need to reset your browser to its default settings.
This step should be performed only if your issues have not been solved by the previous steps.

Google Chrome

Google Chrome has an option that will reset itself to its default settings. Resetting your browser settings will reset the unwanted changes caused by installing other programmes. However, your saved bookmarks and passwords will not be cleared or changed.

Click on Chrome’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled Settings.
Chrome’s Settings should now be displayed in a new tab or window, depending on your configuration. Next, scroll to the bottom of the page and click on the Show advanced settings link (as seen in the below example).
Chrome’s advanced Settings should now be displayed. Scroll down until the Reset browser settings section is visible, as shown in the example below. Next, click on the Reset browser settings button.
A confirmation dialog should now be displayed, detailing the components that will be restored to their default state should you continue on with the reset process. To complete the restoration process, click on the Reset button.

Internet Explorer

You can reset Internet Explorer settings to return them to the state they were in when Internet Explorer was first installed on your PC.

Open Internet Explorer, click on the “gear icon” in the upper right part of your browser, then click again on Internet Options.
In the “Internet Options” dialog box, click on the “Advanced” tab, then click on the “Reset” button.
In the “Reset Internet Explorer settings” section, select the “Delete personal settings” check box, then click on “Reset” button.
When Internet Explorer has completed its task, click on the “Close” button in the confirmation dialogue box. You will now need to close your browser, and then you can open Internet Explorer again.

Mozilla Firefox

If you’re having problems with Firefox, resetting it can help. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history and open tabs.

In the upper-right corner of the Firefox window, click the Firefox menu button, then click on the “Help” button.
From the Help menu, choose Troubleshooting Information.
If you’re unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting information page.
Click the “Refresh Firefox” button in the upper-right corner of the “Troubleshooting Information” page.
To continue, click on the “Refresh Firefox” button in the new confirmation window that opens.
Firefox will close itself and will revert to its default settings. When it’s done, a window will list the information that was imported. Click on the “Finish“.

Your old Firefox profile will be placed on your desktop in a folder named “Old Firefox Data“. If the reset didn’t fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don’t need this folder any longer, you should delete it as it contains sensitive information.
