Extracting text from a PDF is a torturous process - it's a fairly secure format. If you want to disable email addresses completely from PDF's then you will need to edit the PHP file calsearch.php

Around line 484 delete the red text:

$data[] = array(htmlspecialchars_uni(strip_bbcode(fetch_trimmed_title(strip_quotes($event['title']), 100), false, true)) . ($recurint ? " ($period - $recurint )" : ''),
str_replace(array("\n","\r"), ' ' ,htmlspecialchars_uni(strip_bbcode(fetch_trimmed_title(strip_quotes($event['event']), 600), false, true))),
date($vbulletin->options['dateformat'],$event['dateline_from']) . ($event['dateline_to']=='' ? '' : ' - ' . date($vbulletin->options['dateformat'],$event['dateline_to'])),
(!empty($event['email'])) ? $event['email'] : ''
 );

OR - if you want to disable PDF downloads altogether then, rather than edit the PHP file, edit the calsearch_result template and delete the red line:

<span style="float:right;">
{vb:rawphrase save}:&nbsp;
<input type="submit" class="button" align="right" name="do" value="i{vb:rawphrase calendar}" tabindex="7" />
<input type="submit" class="button" align="right" name="do" value="PDF {vb:rawphrase calendar}" tabindex="8" />
</span>
