I'm just a little panicked because as soon as I start the PC there are several displays that my desktop is being recycled. Everything I click on is moved to the trash. I always had my anti-virus programs on, but Kaspersky e.g. Does not show threats. Does anyone know what I can do to not lose all my data?
You may have accidentally assigned the buttons on your mouse with the delete command, which is basically possible with programmable mice.
In that case, you would have to navigate with the buttons and undo this in the mouse settings.
With a screenshot it would be much easier to understand.
You basically only broke a virus program, for Windows 10 the Defender is enough.
The problem is that you can't save anything because it contains important data.
