spambotEmailProtector error

Hi,

I have a link on one of my page:
<a href="zip_download.php?files=<?php echo $record['num']; ?>" class="sepV_a" title="Download"><img src="img/ico/download_gray.png" alt="" /></a>
that trigger to download a dynamically created zip file, everything works ok until the zip file is "too big" (100mb), then i got:

[17-Apr-2012 19:06:16] PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 110684390 bytes) in /home/eye360/public_html/bcm/plugins/spambotEmailProtector/spambotEmailProtector.php on line 33

after i disabled the spambotEmailProtector, the download link is working with the same file.

the setting for the spambotEmailProtector are:
$GLOBALS['SEP_ENCODING_METHODS']['decEntity'] = true;
$GLOBALS['SEP_ENCODING_METHODS']['hexEntity'] = true;
$GLOBALS['SEP_ENCODING_METHODS']['urlEncoding'] = true;
$GLOBALS['SEP_ENCODING_METHODS']['jsUnicode'] = true;
$GLOBALS['SEP_ENCODING_METHODS']['bdo'] = true;
$GLOBALS['SEP_ENCODING_METHODS']['comments'] = true;
$GLOBALS['SEP_ENCODING_METHODS']['tags'] = false;
$GLOBALS['SEP_ENCODING_METHODS']['jsLocation'] = true;

Why the plugin check this specified download link and how can i disable it for the link only and not globally to fix the issue?

Thank you in advance,
Karls
