MacBook displays the message "A system dialog displayed"

Hello,

When I don’t use my MacBook for more than about 15 minutes, the desktop locks and then displays and vocalizes the following messages:

First: “1 system dialog displayed”
Then: “application, connect, window ...”
And finally: “You are currently on a text field. Type to enter text in this field. This is a secure text field. Any text entered...”

For your information, I have a 13-inch MacBook from 2008 - 2 GHz Intel Core 2 Duo Processor - 4GB 1067 MHz DDR3 Memory - Graphics NVIDIA GeForce 9400M 256 MB - OS X Yosemite version 10.10.5

Here is the list of attempted manipulations that did not resolve the issue:

1- I checked the “VoiceOver” function; it is not enabled...

2- In System Preferences, under Users and Groups, it’s my session (admin) that is scheduled to open. So there doesn’t seem to be any application running in the background.

3- In Security and Privacy, under General, the “Require password” action is indeed disabled/unchecked.

4- I also proceeded to reinstall the OS X Yosemite system (version 10.10.5) from the OS X Utilities by booting from the recovery partition (holding down the cmd and R keys on startup), but without success.

Does anyone have THE SOLUTION?

Thank you very much in advance for your help.

    Good evening,

    Maybe an adware, installed without your knowledge, during a visit to a "weird" site and running in the background!
    Try installing MalwareBytes and run a check on your Mac with it.
    A bit of reading, just in case:

    When everything has failed, read the manual ;)

      Despite checking my MacBook with MalwareBytes, the issue persists :-(

      Do you have another solution please?
