Hi,
i can't tell when it happened, but i installed the classic editor plugin
and after opening some of my posts this lines where modified:

<font size="3em" style="font-weight:bold;cursor:pointer" onclick="window.open('/cgi-bin/mp_load.pl?dl=4XZ')">[xmlgrabandstore4me.zip]</font>
<br>
<font size="3em" style="font-weight:bold;cursor:pointer" onclick="window.open('/cgi-bin/mp_load.pl?dl=4XR')">[xmlgrabandstore4me.rar]</font>
<br>
<font size="3em" style="font-weight:bold;cursor:pointer" onclick="window.open('/cgi-bin/mp_load.pl?dl=4X7')">[xmlgrabandstore4me.7z]</font>
<br>
<font size="3em" style="font-weight:bold;cursor:pointer" onclick="window.open('/cgi-bin/mp_load.pl?dl=4XE')">[xmlgrabandstore4me.exe]</font>
<br>
<br>

<p><span style="font-weight: bold; cursor: pointer; font-size: medium;">[xmlgrabandstore4me.rar]</span></p>
<p><span style="font-weight: bold; cursor: pointer; font-size: medium;">[xmlgrabandstore4me.zip]</span></p>
