Site origin add automatically code in the source code?

If I add a new page and switch between visuell and text and back again a get this Code automatucally written in my source:

<div id=”kpm_hint” class=”kpm_locale–de”>
<div id=”kpm_hint-pointing_arrow” class=”kpm_hint-pointing_arrow kpm_hint-pointing_arrow–left kpm_reset”></div>
<div class=” kpm_hint-header kpm_reset”>
<div class=”kpm_hint-name kpm_reset”>Kaspersky Password Manager</div>
 

<div class=” kpm_hint-description kpm_reset”>Erstellen Sie ein sicheres Kennwort für Ihr Konto.</div>
<button id=”kpm_hint-open_popup_button” class=”kpm_popup-button–green kpm_hint-gen_pwd kpm_reset”> ERSTELLEN </button>
<div class=”kpm_reset”><label class=”kpm_hint-do_not_show_hint kpm_reset”> <input id=”kpm_hint-do_not_show_hint” class=”kpm_hint-do_not_show_hint_checkbox kpm-checkbox kpm_reset” type=”checkbox” /> Nicht mehr anzeigen </label></div>
</div>

Is this normal?? Or what is this??
