We are experiencing a strange bug on our website which we think is related to the software installed on user's computers. We have an e-mail link on a lot of pages, which is created using Javascript (so spambots won't get it).
It seems the link is "clicked" automatically on some user's machines. Some users then discard the window by clicking Send on the e-mail window that pops up, resulting in a ton of e-mails to us.
When inspecting the Apache log, nothing weird can be seen in the browser string. Can this be a download accelerator/prefetcher gone haywire? Any other theories as to what this might be?
The link in the HTML is written like this (it is autogenerated by Smarty):
<script type="text/javascript" language="javascript">
<!--
{document.write(String.fromCharCode(60,97,32,104,114,101,
102,61,34,109,97,105,108,116,111,58,115,117,112,112,111,114,
116,64,112,114,111,118,101,46,110,111,63,115,117,98,106,101,99,
116,61,82,101,102,101,114,97,110,115,101,110,117,109,109,101,114,
37,50,48,49,53,48,48,34,32,62,83,101,110,100,32,115,112,38,111,115,
108,97,115,104,59,114,115,109,38,97,114,105,110,103,59,108,46,60,47,97,62))}
